[GeoMechanicsApplication] Investigate the coverage of the "small" and "nightly" test suites

[rfaasse]

In order to decide which test suite we'd like to run on GitHub, we need to know about the coverage of the "small" and "nightly" test suites.

The small + nightly suites have the following numbers for coverage (the htmls are found in the teams channel for further inspection):

We see there is quite a difference in coverage between the two suites. Of course there is a balance between time it takes to run a suite and the coverage we're able to achieve.

Small suite

Small + nightly suite

Using this data, it is possible to drill into the parts which have a significant difference in coverage and see if it's possible to increase the coverage of the small suite by moving around some test cases, while not increasing the run-time too much.

@mcgicjn2, this was an issue I picked up as something I wanted to do during the 'Christmas Break' sprint. I would propose to close this issue (as I think I worked somewhere around 3-5 days on this already) and create some follow-ups to pick up work like:

• Improve the coverage of the small suite
• Create a kp command to locally be able to produce CC for test suites/UTs
• Run coverage for several different test suites in TeamCity (so we don't only run coverage for unit tests
• Investigate which test cover what functionality specifically (maybe part of revisiting the test cases)?

Etc. For now it has been useful to look at this, we were able to move some tests from nightly to validation (see #12990).

May I ask what should be done with the branch that is open ?
