What is Crowdtesting?

Crowdtesting (or crowdsourced testing) is a practice that harnesses crowdsourcing's efficiency and diversity for software testing. Software such as mobile apps, SaaS, native desktop applications, or websites in various development stages gets distributed to a large group of people. The people in this group, the crowdtesters, run the software on their computers or mobile phones to inspect it for defects and areas for potential improvement. At test IO, these crowdtesters don't need specific scripts; teams usually ask them to evaluate sections or features of the application, using their experience and best judgment to unearth and identify problems. After being examined by a senior tester for quality, reports from the testers flow back to the software team.

Product, development, and QA teams can use the crowd for regression testing, feature testing, usability testinguser story testing, cross-browser testing, accessibility testing, performance testing, routine sanity testing, and so much more. The power of crowdtesting comes from the vast pools of testers, comprised of people with different skills, inclinations, experiences, and devices. Their broad hardware coverage, combined with their human intelligence, gives even fast-moving development teams real-world testing capabilities that wouldn't have been possible a few years ago.

Human Diversity 

Software testing benefits from the diversity of the crowd. It ensures a wide range of attributes and characteristics that in-house QA teams typically can't match, including: 

  • Locales and languages 
  • Levels of expertise 
  • Demographic characteristics 
  • Life experience and affinities 

By making sure a diverse group of testers evaluate a project, a QA team can feel confident that their software has been thoroughly assessed by people who did not create it. This is important because crowdtesters do not have the embedded biases and expectations testers from within the company would. Furthermore, including testers from different backgrounds, countries, and ages, as well as other characteristics, helps catch any other assumptions that may be built into the product.

Crowdtesting also gives companies the chance to try out their products on testers similar to their target customers. With a big enough pool of potential testers to draw on, it's possible to set up a test with people who closely track these characteristics, whether it's age, country of origin, or another attribute. By assembling crowdtesters who are, for example, Facebook power users, train commuters, or enthusiastic video gamers, a product team can test on a group like their customers without actually testing on their customers.

Hardware & Environmental Diversity 

In addition to the broad spectrum of people, crowdtesting also means that companies can test their software on a massive variety of devices in many different real-world environments. The more testers in the crowd, the more diverse the devices they're using to run your software will be. This includes variations in form factor, hardware, and operating systems. Even different OS versions present some of the greatest development challenges – Android is a prime example.

Crowdtesters don't merely follow scripts the way an automated test would; they use their human discretion and accumulated knowledge to discover functional and user experience flaws in products and platforms. Testers use their devices as real users do, with privacy settings, ad blockers, and locales configured to provide realistic scenarios unattainable in a lab setting. With dozens or hundreds of testers, crowdtesting provides real user testing in highly varied real-world conditions at unprecedented scale and efficiency.

Efficiency & Scalability 

Testing at scale on a multitude of hardware and software combinations doesn't have to be limited to big consumer software corporations who try out new code directly on customers. Crowdtesting enables smaller or non-consumer-facing software companies to test their software at scale in real-world conditions. This means they're better prepared and more confident when releasing to broad audiences.

Crowdtesting adds both flexibility and extra testing resources when software teams need them most. Setting up regular crowdtests means QA can keep up with the continuous development cycle. When a milestone approaches, testing doesn't have to fall by the wayside or get pushed to the end. Crowdtesting is available on-demand and doesn't redirect development resources. Right before a big release, crowdtesting is flexible, so you can get dozens or hundreds of testers for a final test cycle without pulling engineers off of development.

Running tests in parallel is another efficiency benefit of crowdtesting. Instead of having one or two testers run through the scenarios and new features in a piece of software on a single device, multiple crowdtesters on different hardware and software can test all the scenarios simultaneously. This gets you results faster and helps to pinpoint problems in specific builds or hardware versions.

Finally, crowdtesting at test IO simplifies the QA team's workflow and eases the burden of testing. You can work with or without detailed test cases: explain what you want in plain language. Our crowdtesters will understand without needing step-by-step scripts. Or if a problem does crop up that would stop an automated test, humans are robust. Human crowdtesters can recognize mistakes or misunderstandings and keep on testing.

Crowdtesting at test IO 

Unlike other crowdtesting providers, test IO has learned to differentiate testers and augment their skills. By selecting capable testers and differentiating them over time, we concentrate on bringing a highly-qualified crowd to the table tailored to the test type. Our testers often already work as software professionals, and they're looking to expand their skill sets or to do challenging and rewarding work on the side. 

All this results in a professional testing workforce you can use to continuously test your software, is flexible enough to add testers when you need them, and is experienced enough to know what you need without scripts or step-by-step instructions.
