Why Google Uses Crowd Testing

Google uses crowd testing to test 14 of its software products. The main reason for this is the opportunity crowd sourced platforms give to test apps in real world conditions. Cost-effectiveness and speed of execution are the other two key benefits of crowd testing. Here are the top reasons for Google’s reliance on crowd testing for its software products:

Why Google uses crowd testing

Why Google uses crowd testing

1) Opportunity to Improve Capabilities

Crowd testing helps Google align their testing efforts with their development plan. Using crowd sourced platforms, it is possible to get testing insights in varied test environments faster. This enables development teams to improve the capabilities of the app. With real insights from real users, Google thus makes its app features better with each build.

2) Reduces Risk of Software Failure

The way an app works in a lab is very different from the way it works in the real world. Crowd Testing gives you a pretty accurate picture of your app’s performance in the real world.  Insights from crowd testing helps Google to focus its attention on critical issues that needs to be fixed. There by it eliminates the risk of software applications, not working in real world conditions.

3) Reduces Costs

There is no fixed head count costs or overhead expenses with crowd testing. Google thus saves big time on investing in full time QA resources when they opt for crowd testing. In an interview the ex-director of Google, James Whittaker explained that crowd testing enabled them to save around 10%-25% of their testing budget while delivering great results. Crowd Testing lowers the cost of finding and fixing critical bugs, before it reaches the customers. You can save about 5x to 10x on testing using crowd sourced platforms compared to in-house testing.

4) Reduces Time-To-Market

Crowd testing improves the internal efficiency of development teams by reducing the time to market. It works well with agile teams and helps in delivery of testing insights faster than traditional testing methods. Google thus enjoys the benefit of better product quality at lower costs with shorter release cycles.

5) Test Coverage

Crowd testing gives you complete coverage across geographies and configurations without any major investments. Further by testing on real devices/ machines and browsers development team can get insights on real world usage of the application which cannot be replicated in a lab-based testing environment. With real world insights on app performance, Google can thus benchmark the quality of their app to other apps in the world.

6) Expertise in Usability Testing

Crowd testing works beautifully in case of user centric apps as you can target your testing efforts to match your target demographics. Thus it works well for Google apps where collaboration is needed between the developers and users of the application.

7) Supports Internal QA

With crowd testing Google ensures quality in the work done by their internal QA team. You can find all the critical bugs before your product reaches your customers. Ideally, it is recommended for companies with user centric apps to allocate 20%-30% of their testing budget for crowd testing to get the optimum results.

8) Flexibility

Crowd Testing can help you handle peak loads or on-demand QA requirements effectively especially in cases where a release has to be made in a short time. You can scale your QA efforts in half the time it takes for normal in-house QA teams to ramp up. Hence, Google enjoys the flexibility through crowd sourcing to scale its testing efforts to deliver new product features faster.

The below video by Ex-Google director, James Whittaker explains Google’s testing strategy:

The benefits of crowd testing have made it a favorite form of testing for even other companies like Apple & Microsoft. Further, companies can ensure secure access to their apps and data by relying on good crowd sourcing platforms. A good crowd sourcing platform verifies testers registered under them and also provide tools for secure/restricted access to apps.

Top 10 Benefits Of Crowd Testing

Crowd testing is basically a form of testing where in a crowd sourced platform is used to connect testers from around the world to testing projects. When it comes to user-centric apps like games and e-commerce apps, crowd testing is the best solution. That’s why corporations like Google & Microsoft rely on crowd testing to test their apps.

While an internal QA check may help out in weeding some of the defects found during a lab-based testing, they can never reproduce the harsh and varying conditions that your app will face out in the open.

Unlike a lab, the real world is far from user friendly. Analyzing how real users react to your app is crucial for identifying and fixing bugs that can affect your app quality.

Crowd testing is not a replacement for traditional internal testing. Instead it is an additional opportunity for app developers to test their app in real world conditions without the hassles of investing in full time QA resources.

Top 10 benefits of crowd testing

Scaling new heights with crowd testing.

Benefits of Crowd Testing:

The following are the top 10 benefits of crowd testing that makes it popular and effective:

1) Scalability

Whether you are time pressed for the release of a product or need to upgrade or improve a product feature within a set deadline to beat the competition, crowd testing can give you the flexibility you need to scale your testing efforts with ease. You can access crowd testers on demand for your project and increase the capability of your development team to build your products faster.

2) Speed

One of the biggest advantages of crowd testing is the flexibility you get for running multiple test cycles at the same time. This will not only help you to get testing insights faster but also help in reducing the time to market.

3) Cost

The best part about crowd testing is that you don’t have to invest in full time QA hires or money on acquiring devices for your testing project. You get a comprehensive test coverage and access to many testers from different locations without any major financial investments.

4) Output based Pricing

Crowd testing is an extremely result driven form of testing where you are charged according to the bugs found by crowd testers. The pay for performance model not only drives the crowd testers to deliver their best, but also enables you to get the best value for money unlike other forms of testing which follows a rigid head count form of pricing.

5) Device Coverage

With crowd testing, you can leave behind the hassles of configuring emulators and the high costs of investing in device farms. You can get coverage across multiple devices and browsers easily without major investments.

6) Geographic Coverage

When you rely on a crowd sourced platform, your QA team is truly global. You can access testers from anywhere in the world. This is especially useful in case of localization testing and other forms of targeted testing based on specific target demographics.

7) Testing in The Real World

Ever wondered, how real users will react to your app? Crowd testing enables you to target your testing efforts with testers who match the interests & demographics of your target group. This will help you in gaining insights to improve app features to delight your users. Crowd testing is thus ideal for usability, functional & exploratory testing.

8) Access Testing Experts

One of the biggest constraints of a traditional QA approach is the limited access to testing talent. By tapping into a global pool of talented testers you can access testing experts in the domain you require easily. Expert support means that your testing efforts can be more effective and simpler.

9) Get A Fresh Perspective

It is possible to unearth new issues and gain fresh app insights with crowd testing as crowd testers would be more impartial & would not have any intrinsic bias like an internal QA team. When you follow new permutations and combinations, the chances of finding issues and bottlenecks are higher.

10) Align testing efforts with development process

Crowd testing gives you the ability to get complete coverage in terms of devices and locations with the flexibility to scale your testing efforts, making it easier for you to plan and align your testing strategy with the requirement of your development team. You can give your development team the timely inputs they need to address critical issues in the application.

Thus, with the right product insights through crowd testing, you can deliver more than what is expected out of your app and delight your users with an incredible digital experience.

21 Infamous & Expensive Software Bugs

Lives today are technology driven. It has become the way of life. Everyone is dependent on it to a very great extent. That is how it seems in this current age as every aspect of a human life is inter wined with technology so much so that we feel crippled in its absence. On the contrary, a glitch in it termed as the software bug can cause undesirable ripples leading to multiple consequences causing more harm than one.

What can happen easily in a jiff with a tap or click collapses the entire system when the software fails.

Simply put, bug can be called as an error or a fault in a software program that gives wrong or an unexpected result. Software after all is developed by a human and therefore is prone to errors as the saying goes – ‘To err is human’.

Defects could be related to functionality, security, user interface, performance (load and stress), hardware, network, third party software, compliance and even testing errors.

Inconvenience to the users, compromise on security, loss of life, money, reputation, business credibility are the consequences of software failures to name a few. Some bugs may cause only trivial problems, but flight control software and software for medical equipment are examples of things that simply cannot be allowed to fail due to programming errors. They can have a catastrophic impact.

21 Infamous & Expensive Software bugs

21 Infamous & Expensive Software bugs

Here is a list of the most infamous & expensive software failures:

1) Software Glitch Causes F-35 to Detect Targets Incorrectly

A serious software glitch in the F-35 Joint Strike Fighter air crafts gathered wide public attention in the month of March this year. The planes when flying in formation were unable to detect potential targets from different angles. In fact the engineers identified that the software bug caused the aircraft to detect targets incorrectly. The sensors on the plane were unable to distinguish between isolated and multiple threats. As reported by Fox News, Air Force Lt. Gen. Christopher Bogdan, Program Executive Officer, F-35 said: “We want to fix this so it is inherent in the airplane. We have always said that fusion was going to be tough. We are going to work through this.” (Source: Fox News)


2) Nissan’s Airbag Software Malfunction

Nissan Motors has been under investigation by US safety regulators for recalling over one million vehicles in the past two years. The vehicles were recalled due to a software failure in the airbag sensory system. The automakers have reasoned that a software glitch in the system rendered it incapable of detecting an adult sitting in the passenger seat. The issue surfaced when two accidents took place and the airbags did not inflate. Several complaints were registered even after the issue was supposedly resolved. Gorge Zack in his article in bidnessetc.com even mentioned that 104,871 vehicles had been recalled by Honda Motors as well due to faulty airbag systems made by Takata. (Source: BIDNESSETC)


3) Tennessee County Court Kills Software System Update worth $1Million

After two years of labor and investment of $1 Million, Rutherford County of Tennessee, United States, had to kill a court software system update. The reason being that software glitches were discovered right when the deal took place as problems regarding the issuance of checks, errors on circuit court dockets and the creation of “phantom charges” arose in the weeks after the program went live. It was reported that even months after training, backlogs were reported in the system. It has compelled the county in killing the system as it fails to deliver. The reporters of The Daily News Journal reported, “After months of work and hundreds of thousands of county dollars spent, the Rutherford County Circuit Court clerk was back to the dot-matrix printers and paper filings they first used 25 years ago.” (Source: Daily News Journal)


4) Software Security Flaws Revealed in OLA’s Mobile App

Ola, India’s largest taxi aggregator based in Bengaluru had serious security flaws in their system. The bugs that were identified made basic programmers to enjoy unlimited free rides- one at the expense of Ola and another at the expense of genuine users as reported by Varun Aggarwal & Malavika Murali in the March issue of The Economic Times. The issue was made public after their customers pointed out the weaknesses in their system. Ola is trying to fix bugs for quite some time now as complaints in their operating system have sky rocketed. (Source: The Economic Times).


5) Starbucks Breakdown caused by Software Bug

Starbucks was forced to close roughly 60% of their stores located worldwide in the month of April this year. The register malfunction occurred because of an “internal failure during a daily system refresh” according to Starbucks. The software failure left thousands of stores across North America unable to proceed with their business as the cash registers were unable to process orders and take payment. Starbucks refused to give any details. Candice Choi, AP Food Industry Writer wrote about the Starbucks breakdown to remind restaurants about how “registers that once merely rang up tabs and stored cash have evolved into hubs that can collect enormous volumes of data and carry out many tasks.” (Source: Yahoo News).


6) United Airlines Grounded All Flights

United Airlines was forced to ground 4,900 flights worldwide for over an hour due to a computer malfunction in the automation portion of their ticketing and  reservation system. The glitch disabled the airline from being able to generate boarding passes, screen passengers, or confirm that all passengers had arrived. Though the system was back up and running within an hour, the ripple effect of so many delayed flights and disgruntled customers took significantly longer to sort out.


7) New York Stock Exchange Suspends All Trading

The New York Stock Exchange placed a halt on all trading due to an undisclosed “internal technical issue”. All open orders were canceled with traders being promised that they would receive information as soon as possible. Responding to the conspiracy theories beginning to arise, the NYSE announced that their malfunction “was not the result of a cyber-breach.” The stock exchange opened again over 4 hours later.


8) The Wall Street Journal Website Goes Dark

Right around the time that the New York Stock Exchange ground to a halt, the website for the well-known financial news outlet “Wall Street Journal” went offline. Initially the website showed a 504 error, which was quickly replaced by a temporary homepage stating that the site was experiencing technical difficulties. The site was back to full functionality within an hour, though that was plenty of time to fan the sparks of conspiracy into flame.


9) Critical Microsoft Glitch Allows Hackers to Take Control

Speaking of hackers, Microsoft released an emergency software patch this July to nearly all of their operating systems. The security flaw was discovered by security researchers, a critical vulnerability buried in the coding of Microsoft’s handling of font files that could allow for hackers to forcefully take over a computer’s operating system. Such a vulnerability exposes millions of Microsoft computers to becoming a hacker’s playground, within nothing barring thieves from stealing data, illicitly installing software, and more.


10)Medicine Infusion Pumps Recalled for Deadly Flaw

It hasn’t been such a good run for CareFusion, a medical equipment manufacturer who has experienced several emergency recalls in recent years. In late May, CareFusion’s Alaris Pump was recalled over a software error that caused the pump, designed to automatically deliver medicine and fluids to hospital patients, to delay an infusion. The consequences, which can range anywhere from medicine being withheld at critical points or accidental over-dosing, can be deadly. Just four days later  CareFusion issued a Class I recall over a separate line of ventilators, citing a software flaw that could cause the patient to suffocate.


11) Prestigious Eton College Accidentally Admits 400 Students

They had only intended to admit 9 boys to Britain’s most prestigious preparatory school, whose alumnus includes Prince William and British Prime Minister, David Cameron. Instead, a “systems error” caused a conditional acceptance letter to be sent to 400 families. The mistake was reportedly caught within minutes, though it left the college with the difficult task of personally contacting hundreds of excited families to break the news.


12) Visa Data Leaked via Software Error

This past July the personal data of visa applicants from over 45 countries was leaked through VFS Global, a visa services company that contracts for international governments. Two technology consultants, themselves visa applicants through VFS Global, discovered the issue when they realized they could input an arbitrary application number and pull up an applicant’s personal information including their name, address, date of birth, passport number, and more. The consultants reported the problem to VFS, though after 15 hours with no response, the pair made the move to publicize the story via news channels. The data leak was no “glitch” in their opinion, rather just the result of gross negligence on VFS Global’s part regarding the security of the user’s personal data. VFS Global countered these accusations by resolving the issue and claiming that the leak was limited to applicants applying for Italian visas.


13) $65,000 Jackpot Declared To Be a Casino Software Error

An elderly Australian woman hit the jackpot this July, only to have it taken away from her. The 82-year-old won a $65,054 jackpot at the Goodna Services Club, however upon reporting her winnings to the club, was informed that a jackpot of that size, on that particular machine, was impossible. As the game was allegedly designed to not exceed jackpots over the $10,000 mark, it was determined that the win must have been due to a software glitch – giving the casino a free pass on paying out the winnings. As would be expected, there has been a public outcry in the local community over the casino depriving an elderly lady of her winnings and the story could very well make its way to court in the near future.


14) Bug Makes 950 Million Android Phones Vulnerable to Hacking

And yet again, the threat of hacking makes the news. Mobile security researchers discovered a flaw in Google’s android software that allows hackers to hijack an Android phone simply by sending the  device a media message. Dubbed “Stagefright”, the message does not even need to be opened for the bug to take effect, exposing over 950 million devices to the possibility of having data stolen, cameras and microphones switched on and recorded, and more – all just by having access to the device’s mobile number.


15) Kanye West Mic Failure

On another, less serious note, Kanye West, music’s current L’Enfant Terrible, experienced a microphone failure at one of his recent concerts. In true West fashion, the rapper responded by throwing a fit, smashing the microphone on stage, and storming off. Can’t say we’re too broken up by that one.


16) Software Bug Cripples Pricing of US Mutual Funds

The biggest financial malfunction of Q3 took place at the Bank of New York Mellon (BNYM), turning the U.S. mutual fund industry on its head for nearly two weeks this past August. BNYM’s software bug, which corrupted the pricing system of the mutual fund giant, affected asset management firms, investment companies, and banks across the United States; sparking hundreds of emergency meetings to sort pricing data and create contingency plans for mispriced sales. Industry analysts called the software glitch the “biggest software stock price issue in more than 10 years” – and that was even before the problem proceeded to drag on for over a week and a half.


17) Multiple Stores across the United States Report Double-Charging Bug

Multiple accounts of grocery stores double-charging customers emerged in early September, with reports spanning from Food Lion in Virginia, to Jewel-Osco in Ohio, Hy-vee in Iowa, and Shaw’s and Hannaford in Vermont. Each story reported that customers paying with debit cards were double-charged for their purchases – sometimes for amounts as high as $600 over their original total. Each of the stores in question cited the same payment processor: NCR Connected Payments. NCR was quick to issue a statement advising shoppers to stick to cash and hold tight until they had sorted and refunded the payments. Days after the story had made multiple national headlines however, many shoppers were still waiting to see their money returned.


18) HSBC IT Bug Delays a Quarter Million Payments

HSBC announced in late August that an IT bug had resulted in the delay of 275,000 payments just ahead of a holiday weekend. The glitch affected more than just individual HSBC account holders – multiple companies found themselves unable to pay their employees as a result of their funds being inaccessible. HSBC stated that the payments, which were due to be transferred on a Friday, would be 99% processed by the following day. As a one-off incident, a day delay in payment is a troubling but forgivable lapse. Unfortunately however, HSBC is just one of the several major British banks that has experienced software meltdowns in recent years – a story that is becoming increasingly common in British newspapers.


19) Automakers Sued For Deadly Flaw in Keyless Ignition Systems

As of August, ten of the biggest names in the automotive industry are embroiled in a lawsuit over a potentially deadly defect in the keyless ignition systems of certain car models. The lawsuit claims that the companies in question intentionally buried a flaw in their keyless ignition system software, a flaw that allows the engine to remain running even once the key has been removed from the car. At least 13 deaths have been attributed to the resulting carbon monoxide build up. Popular cars cited in the lawsuit include BMW’s Mini, Daimler’s Mercedes Benz, Honda’s Acura, and Toyota’s Lexus – to name just a few. Aside from damages, the lawsuit is seeking to have the automakers revisit their keyless ignition system software to add an automatic shut-off feature.


20) Air Canada Refuses to Honor Glitch that Sold Flight Packages for 90% Off

Air Canada’s website pricing glitch was an unfortunate but relatively common error in the world of online shopping.  It was the events that transpired afterwards however, that catapulted the story into the spotlight this past August. When Air Canada mistakenly advertised a 10-pack of flight passes valued at $8000 for only $800, several shoppers were quick to jump on the deal. Air Canada quickly realized their error, fixed the pricing, and canceled the transactions. Problem solved, right? Wrong. The incensed would-be ticket holders have saddled Air Canada with a class action lawsuit, stating that the airline has a contractual obligation to honor the price of the tickets purchased.


21) Yahoo Japan System Glitch Loses 2.58 Million Emails

Yahoo Japan reported a software glitch this past August that resulted in the loss of 2.58 million emails from around 970,000 accounts. The system failure that resulted in the lost emails lasted for roughly 10 hours and cut off account access for 2.6 million users. At the time of the article publication, Yahoo Japan had not yet disclosed the source of the issue – only claiming that 60% of the emails were “spam” that would have been blocked by the recipient anyways. There was no word on whether the other 40% of emails would be recovered, leaving account holders to wonder what important, life changing news they may have missed.

Top 5 Parameters For Choosing Devices For Mobile App Testing

Every mobile app is unique. So is the mobile device, it works on. Today, mobile technology is growing at an exponential rate. Just how fast is the growth? The number of mobile devices is growing at a rate that is 5 times more than the number of people on earth!

Ensuring that your app works flawlessly on mobile devices of various configurations is a complex & challenging task. To make your app a worldwide success, your app testing strategy needs to effectively cover device diversity.

Top 5 Parameters For Choosing Devices For Mobile App Testing

Top 5 Parameters For Choosing Devices For Mobile App Testing

Parameters for Choosing the Devices

As mobile technology evolves, new versions of mobile devices emerge. Each model comes with its distinct features in terms of OS, screen size and other aspects.  You have to factor in not only the OS of the device but also the OS version. It is critical that you choose the right number and type of device to test your mobile app. The following are the 5 parameters for choosing devices for mobile app testing:

1) Market share

First step is to identify the devices that are popular with your target demographics. You need to select the devices based on their popularity in the geographical markets that you are targeting. Your list should include all the important devices relevant to your market. Take into account the market share of each device before shortlisting it. Do factor in the critical features you want to test and the number of releases you plan for the year.

2) OS & OS Version

To ensure that your app supports various platforms, you need to test your app on different OS and their versions. Focusing on a single platform will narrow down your market share and slow down your expansion to newer markets. Framework and characteristics of various OS vary wildly from each other. Based on OS, the biggest market share goes to Andriod based devices where device fragmentation is highest. Android’s market share is nearly 6X more that IOS devices. Popular Andriod versions include Jelly bean, KitKat, Froyo, Gingerbread and Ice cream Sandwich. As your app expands to new markets, you need to include more devices in your testing strategy. You also need to ensure the updates you release work well in different OS versions.

3) Manufacturers

Top brands for android devices include Samsung, Motorola, HTC, LG & Google Nexus. You can create an app testing device matrix to identify the combination of devices that can get you the broadest coverage in terms of OS, model and brand. You can prioritize the devices as most important, secondary and additional based on their relevance to your target demographics.

4) Hardware

Based on the phone’s model, the attributes and characteristics differ. While selecting a device for testing you need to take into account, its screen size, resolution, PPI & other hardware features that can impact your app’s performance. You should also check the disk space & data consumed by your app. Your app is also affected by the processing power of various devices.

5) Network

With over 400 different mobile networks in the world supporting various network technologies like GSM & CDMA, it is crucial to factor their impact on the performance of your app. To understand the effect of network and varying conditions posed by location, it is necessary to study the app in real world conditions. Crowd sourced testing is a viable and cost-effective solution for testing your application on different networks in various locations.


Challenges In Attaining Device Coverage

Traditional approach to meet device coverage involves the use of in-house devices and lab-based emulators. The cost of acquiring all the mobile devices in the market is very high & non-viable. Further, testing your app on a handful of in-house devices will not help you in getting an accurate picture of your app’s health.

Depending only on emulators implies more hassles in configuring them and the risk of getting inaccurate results. They can never replicate the quirks and characteristics of a real device.

Another option is to depend on device farms. However, the charge for device farming is hefty and every minute of a device you farm, will cost you money.

To grow big, you need greater test coverage that can ensure your app’s success on a large number of devices. A healthy mix of emulators and real world testing can give you the device coverage you need to make your app successful.


Key Advantages Of Crowd sourced App Testing

With crowd sourced app testing, you can test your software application in real world scenarios to ensure that it works as per expectations. The key merits are as follows:


Speed: Crowd testing enables you to run multiple test cycles simultaneously, delivering faster results and reducing the time to market.


Cost: Crowd testing is a performance based and cost- effective form of testing that gives the most accurate results minus the investment in full time QA hires, expensive device farms and in-house devices.


Scale: The scope for scaling is more with crowd testing as you can access many testers from diverse back grounds to work on your project.


Coverage: With crowd testing you can test your application across different configurations and locations with a global team of crowd testers.


By analyzing your app quality goals and target demographics, you can strategize the type of mobile app testing and extend of device coverage required to make your app a winner.
