Few years ago, at a new job, we started our investigation on how to best organize numerous test cases that existed in the company. Tests were documented in spreadsheets, tracking was done manually through e-mail, status had to be requested from the leads and generally no one knew exactly what was being tested. We investigated all of the popular test case management tools. Most were complicated, requiring phone meetings with reps, sales intros before we had permission to test the tool and generally were not easy to understand.
TestRail seemed obvious from the start. We obtained a demo license within hours and had a full instance ready for our test. From the start it was obvious how to create projects, test suites, test cases, create releases and just about everything else. In two instances (during the demo period) we e-mailed for support, asking about specific features. Both e-mails were responded to within a day. We implemented the tool in the company and repopulated all of our tests within a few weeks. The test process improved dramatically. We could easily set up milestones, issue test suites to testers, track their progress in real time, manage different configurations, and all that with very minimal training of the testers. Writing new tests was easy. JIRA integration was simple but sufficient. In later stages with started populating automated test results through the API and that worked great as well.
I am not getting paid for this review. It is just a tool that works. It was $25 per user last time I checked (March 2014) and it is worth every penny. In the almost two years of use the hosted version never went down and was completely reliable. Everyone in the company knew at every point in time what is being tested, what the current status is, where the issues are and also look at pretty graphs. As a result, several important suggestions were made to improve the test bed resulting in better software.
Totally recommended for test case management and test execution tracking. There are a ton of other features that I did not even touch upon. Best to see that on their web site.
