Runs all test and reports the results using the given test reporter.

If no reporter is specified, a reasonable default is provided.

This function demonstrates the expected workflow with this testing system:
|
|
1. Locate test modules
|
|
2. Generate test plan
|
|
3. Run test plan
|
|
4. Report test results
|
|
|
|
This means we could hypothetically present a GUI to the developer that shows
|
|
the test plan before we execute it, allowing them to toggle specific tests
|
|
before they're run, but after they've been identified!
