Business Challenge 

During the development of Wizz Air’s digital platform (wizzair.com), ensuring the quality of software releases, reducing the number of defects, and accelerating development cycles became increasingly challenging. Manual regression testing required significant resources, while defects were often discovered only during the deployment phase, resulting in delays and additional testing cycles. 

Existing testing processes were not sufficiently integrated into the development lifecycle and lacked the transparency and efficiency needed to support rapid releases. Wizz Air aimed to implement a sustainable, scalable test automation solution capable of enabling faster, more reliable software deployments. 

Solution 

The project aimed to reduce the time spent on manual testing by automating existing regression and component tests, increasing test coverage and accuracy, and enabling faster and more secure releases. As part of the initiative, we designed a comprehensive software quality assurance process and methodology that combined manual and automated testing steps, covering the entire development and operations lifecycle. To support this approach, we initially selected and implemented Ranorex, one of the leading test automation frameworks, later transitioning to the Playwright platform to better meet evolving project needs. 

During implementation, the tests were integrated into the CI/CD pipelines and are now executed automatically during both the development and release phases. Testing is performed across multiple environments (Test, UAT, Staging) and browsers (Chrome, Firefox, IE), either on a scheduled basis or triggered manually. 

As part of the continuous refinement of the QA concept, we adopted a “shift-left” approach, involving developers in the design of various test components already during the development phase. Test planning became an integral part of sprint planning, with clear responsibilities defined for each testing level. Today, more than 100 professionals — including developers, manual testers, and automation engineers — work in close collaboration to ensure consistent quality and efficiency across the platform. 

Results 

As a result of the project, testing time has been significantly reduced: while manual testing previously required an average of 1 to 1.5 hours per test case, automated execution now runs independently without any human intervention. 

95% of regression tests have been automated, significantly reducing the number of release defects and shortening release cycles. Early detection of development issues has decreased the number of bug fixes required during the release phase, while improved test planning and execution throughout development cycles have resulted in more accurate estimations and greater overall efficiency. 

Thanks to the development, Wizz Air can now respond to market demands much more dynamically, releasing new features and services to the portal on a daily basis if needed.
