# This can be used to run a single test in the context of a test runnner
# Usage: ./run-single-test.sh [skip] test-scripts/my-test-case.sh

# IMPORTANT:
# With the "skip" flag one can disable default exceptions and errors checking in log files. This should be done carefully though.
# A valid reasons for doing so could be e.g killing TMs randomly as we cannot predict what exception could be thrown. Whenever
# those checks are disabled, one should take care that a proper checks are performed in the tests itself that ensure that the test finished
# in an expected state.
