Subject: testlib: Run test result expectation tests with stdout as output
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For historical reasons a few of the subtests are skipped when
running with anything but the plain text logger to stdout.

To ensure we have as broad test coverage as possible for the
expected output of the various loggers we run these tests in
stdout-mode.

Pick-to: 6.2
