Most of my thoughts on testing have ended up in the reading.

Basic Idea

• We verify the correctness of procedures by running tests that compare predicated values to actual values.

Model

• We do a single comparison with check-equal? (or some variants).
• We group one or more comparisons into a test case with test-case. That lets us add a description to the checks.
• We group one or more tests or comparisons into a test suite with test-suite. Unlike test-case, which runs the test,, test-suite builds a value that you run later.
