The challenge: How can I ensure the functionality of my software on all the different devices in the market?

Continuously testing software on all of the latest devices, operating systems and browser versions requires an enormous amount of resources. Despite a strict time schedule, performing flexible yet extensive tests and identifying errors that have been missed during the internal quality assurance process is crucial. However, access to a group of testers with all the devices necessary, who are able to perform a test under real world conditions, is bound to amount in high costs and take a lot of time.

The solution: The crowd tests your software on their own devices

In exploratory bug testing, your software is tested with user stories and predefined tasks while still allowing testers to maintain the freedom to complete each step in their own way. Every detail of the testing procedure is documented by the crowd, giving you a concrete idea on how your application or website behaves on a variety of devices. This process of testing outside of laboratory environments helps discover the bugs that lead to the most common errors encountered after a product’s release. Our crowd features over 500,000 devices with a never-ending combination of operating systems and software. Our exploratory tests provide you with invaluable functionality feedback concerning your product from the point of view of your end user. With exploratory crowdtesting, operational blindness is a thing of the past.

Landal GreenParks

How Landal GreenParks uses testing to optimise the guest experience
“Working with Testbirds led to us professionalising our testing process, as it forced us to critically examine our own testing structure. It definitely made our organisation more mature in that respect. Furthermore, crowdtesting has proven to be efficient. We can start testing on a Monday and see the results on Tuesday. It’s a powerful addition to our development process.”
Lieven Swinnen, Manager e-Business, Landal GreenParks

Three Bug Tests for High-class Media Centres
“The tester feedback was very useful for us. They discovered indeed a few critical bugs. But it’s always better the testers encounter the bugs, and not the end-users.(…) We could export the bug list from the platform very easily and pass it on to our developers. That way we know exactly when and on which devices the bugs occurred”
Urszula Styrczula, Customer Care Manager at

How it looks in practice

The appstore rating of one of your applications is much worse in the Google Play store than in the Apple Store due to a number of bad reviews about bugs. We start a test using a tester group of 25 Android users from our crowd, each operating Android 4.0 to 6.0 devices. After only a few days, the final test report yields 59 bugs. They can all be reproduced on our platform, or “Nest”, with the help of Virtual Machines. Most of them are easily fixed, such as faulty hyperlinks or images, but there are also seven severe bugs that lead to the application crashing. By fixing those errors, the app is successfully optimized for Android devices, raising the Google Play store rating.
