Add name of test case to output in case of run time error

[ReneSpronk]

Currently the output from VSCode lists the directories of all available test cases. This is followed by evaluation results for these test case. It isn't however obvious which output belongs to which test case. This is especially true for test cases where the data results in a run time error (in my case, for training purposes, a dateString that can't be case into a DateTime).

Suggest to print a sequence of ( name of the test case / test directory, test output ) to ease the process of identifying the test case a particular output snippet belongs to.
