run-tests.sh - Run tests from a directory

It looks for all executable files named "test_*.sh" and execute them one after the other.
If there are any failures, it will stop straight away (by default).

Usage:
    run-tests.sh [--directory=<TestsDirectory>] [--continue-on-failure]

Options:
    -d <TestsDirectory>, --directory=<TestsDirectory>
        Run all tests from the specified directory; if not specified, a directory called "tests" in the current
        directory will be used.

    -c, --continue-on-failure
        Continue on failures
