I used the second infrastructure for the TIMESTAMP tests apparently.
Those feel similar to the tests in RunCMake e.g. lots of files that I 
would prefer to combine into something more compact.

The other infrastructure I don't think I have touched but optically it 
looks very noisy.

Having something that takes away repetitive tasks, more compact and 
easier on the eye would be nice.
