[INFO] [stdout] All tests have their standard output and standard error captured by default.
[INFO] [stdout] This can be overridden with the --no-capture flag to a value other than "0".

[INFO] [stdout]                         test, then the test runner will ignore these tests during
[INFO] [stdout]                         normal test runs. Running with --ignored or --include-ignored will run
[INFO] [stdout]                         these tests.
