@SkorikSergey : CheckUserEnvsTest.spec.ts test name is too vague, IMHO. What do you think about naming the test more straightforward, like: UserSecretsInWorkspace.spec.ts?

Yes, that is better. I will rename it to UserSecretsInWorkspaceTest

@SkorikSergey : Test prefix in a script name is redundant. Look at the other test script names in the specs folder.
