Challenge: The platform’s QA framework lacked sufficient test coverage, making it difficult to manage concurrent regression tests across mobile platforms and verify ticket tasks effectively.
Solution: Toptal introduced a structured testing approach that enabled same-day regression testing for iOS and Android, along with efficient ticket verification. TestRail was implemented for test case management and Jira for task documentation, improving clarity and collaboration through regular meetings with management.
Outcome: The structured approach increased test coverage, helping identify and resolve critical bugs before major releases. Enhanced QA processes improved operational efficiency, boosted confidence in releases, raised user satisfaction, and reduced downtime.
