About
TestRail is a web-based test case management platform that provides QA teams with a structured environment for writing, organizing, and executing test cases, tracking test run results, and generating reports that communicate testing progress and quality metrics to project stakeholders. The platform was created by Gurock Software, a German software company, and was acquired by Idera in 2017, expanding its distribution through Idera's portfolio of developer and testing tools. TestRail's core value is bringing discipline and traceability to manual and automated testing workflows that would otherwise be managed through spreadsheets, wikis, or informal processes — its hierarchical test suite structure, reusable test case library, and run/result tracking model give QA teams a single source of truth for what has been tested, what passed or failed, and what remains to be verified before a release.
