Our engagement

Xola's partnership with DeviQA has significantly improved the stability and robustness of its product

We've improved the description of tasks to make them clearer for a team. Bug reports now contain all necessary details and attachments as well.

We've written a lot of new test cases for sub-apps and created a comprehensive suite of over 3200 automation scripts with more than 8300 checks. This enables us to complete regression testing in just 2 hours, allowing Xola to release updates 1-2 times a day.

We follow best practices in automated testing like the Page Object pattern, test independence, API data management, and informative HTML reports. We've automated regression testing for 6 different apps, set up 6 CI pipelines with the help of a DevOps engineer, and improved efficiency with over 70 parallel threads.

Our meticulous bug-tracking process has identified over 2400 issues, with 70% of them categorized as blocker, critical, or major.

Our dedicated team of 6 Full-Stack QA Engineers utilizes advanced technologies and tools such as Jira, Confluence, Java, Selenide, Selenium, Cucumber, REST Assured, Gauge, GoCD, Postman and FullStory, ensuring the success of Xola's projects through thorough quality assurance.
