# Frequently Asked Questions

## Can I have multiple effective Test Executions for a single Test Case in a version?

By default, Ketryx will only display the most recent Test Execution for a given Test Case in a particular version. The latest Test Execution is considered the "effective" execution, and that is what will appear in the Tests screen, Traceability Matrix, and release documentation. However, you may have a scenario where you need multiple Test Executions to be effective for one Test Case in a version.

In this case, it is recommended that you use the Ketryx default _Testenvironments_ field on the Test Executions to capture multiple executions of the same Test Case. The _Testenvironments_ field is a comma-separated list of environments that allows multiple executions to be effective for the same Test Case.

In the case where there are 2 Test Executions that execute the same Test Case, one with "RC1,RC2" in _Testenvironments_ and another with "RC2,RC3" in _Testenvironments_, Ketryx will consider both TEs to be effective and will show both associated with that TC in the UI and release documentation. This is because the first has the _Test environment_ "RC1" where the second does not, and the second has the _Test environment_ "RC3" where the second does not.

This could also be leveraged to sequence the testing throughout the cycle, given that you could search for Test Executions whose _Testenvironment_ fields contain "RC1" and then assign only those in the first round of testing.
