Provide a way to review test failure details during a live long run

[vkarak]

If a test suite runs for too long, in case of single test failure, there is only a single line being printed describing in which stage the test has failed and where it's staged. Although that's a first step, it would be nice to be able to query the details of a failure during a live run. This becomes more relevant with the introduction of options that allow continuous repeated testing as in #2839.
