The TERM env variable cannot be found, or is empty:

runtime/src/libraries/System.Console/tests/Color.cs

Line 75 in 0d848f6

    
           public static bool TermIsSet => !string.IsNullOrEmpty(Environment.GetEnvironmentVariable("TERM"));

Actual: Test Condition(s) not met: "TermIsSet"\n

When tests run in parallel, reading from Console.Out mangles the ReadToEnd output and therefore, SetOut tests intermittently fail. Condition(s) not met part is the output of previous skipped test. We can disable parallelism by adding [Collection(nameof(DisableParallelization))] on this class once PR #62132 is completed and delete ActiveIssue.
