I realized that I could implement this what by adding multiple test results to the same test instance (TXXX) and label every result with specific custome parameter value.
The final test status for test is implemented as last test status.
In my case it should be “worst case” - e.g. one test results is FAILED than final status should be FAILED.
Is it possible to have control over final status calculation method in Test Rail??
What is more complex, I will also have “normal”, not parametrized test cases, executed only once per test run and the current method of final status calculation is proper for them…
similar topic I found in Aggregate Multiple Results
The generation of custom reports is not a solution for me, because depending on test case, I need to apply different method for “final test status” calculation
