In my Testrail I have a project with several test suites, each is representing different functional area in the application, and each contains about +100 test cases. Each test case has a type which can be any of: Sanity, Regression, E2E, … same as described by @aniket. Having test suits, for each functional area, is more logical to me, and makes the navigation between tests more easy.
What I’m looking for is the option to create a test run from multiple test suites, so I will be able to test ‘Sanity’ cross project in a single test run.
I understand that having a single test suite will work, but this also means having MANY test cases, hundreds of test cases in the same test suite which will make it very hard to navigate. Even breaking them by sections still i think won’t help much when I will start having +1000 test cases.
