- * This is the base class for all test cases. Test are performed using an assertion method. If the
- * assertion is correct, the test passes, otherwise it fails. Most assertions take an expected
- * result, a received result, and a message (to describe the failure) as parameters.
- *
- * Available assertions are (see `assert<assertion-name>` methods for details): Equal, False,
- * Identical, NoPattern, NotEqual, Null, Pattern, Tags, True.
- *
- * If an assertion is expected to produce an exception, the `expectException` method should be
- * called before it.
- *
- * Both _case_ (unit) and _integration_ tests extend this class. These two test types can loosely
- * be defined as follows:
- * - Case: These tests are used to check a small unit of functionality, such as if a method
- * returns an expected result for a known input, or whether an adapter can successfully open a
- * connection.
- * - Integration: These are tests for determining that different parts of the framework will work
- * together (integrate) as expected. For example, a model has CRUD functionality with its
- * underlying data source.
