This MR provides a pretty print on terminal for the test output. This may produce a relatively long output, but it's far more clear.
For debugging. In the near future we can use this for evaluating the build process in the CI.
I didn't write any new functions.
Are there parts of the documentation we have to adjust?
Are we able to test this new feature?
Via command line output.
I added a statement to the CHANGELOG.
Closes #92 (closed)
