Subject: [PATCH 3/3] sysclt: Clarify the results of selftest run
From: Joel Granados <j.granados@...sung.com>
In some cases the result of test were hidden inside the stdout and it
was difficult to identify when a test was skipped and why.
List of changes
1. Capitalize all the words that express a test result : "OK", "SKIPPED"
and "FAIL".
2. Place all test result text at the end of the message. This will
prevent the result from being hidden when stdout is verbose.
3. Any other explanation that comes after the result text will be placed
in a new line.
4. All failures are marked as "FAIL"
5. Pipped the failure to stderr in tests 8, 9, 10.
6. Replaced bogus "FAIL" with "SKIPPED" in test 0007
7. All "..." are prefixed and followed by a space.
