Here are some rules that we follow when developing jMock:
* Never check in a class without associated unit tests.
* Never check a failing unit test into the CVS repository.
* Acceptance tests may fail. A failing acceptance test indicates
something that needs to be done: a todo item, feature request or
bug report, for example. It's ok to check a failing acceptance test
into the CVS repository.
* Separate acceptance and unit tests. Make it easy to run only the
unit tests so that we can check that they pass before committing,
even when acceptance tests are failing.
* Resolve and remove all TODO comments before checking in.
* Avoid the following words in class names and other identifiers:
Helper, Impl (or a derivative), Manager.
* And the reverse: don't start interfaces with an I.
* Follow the Sun: use Sun's coding conventions for Java1.
* Use the TestDox naming conventions for unit tests.
* No dependency on any specific test framework.
That means, don't use JUnit Assert.assertBlahBlah to check expectations.
Throw ExpectationError to report a violated expectation.
Throw some kind of RuntimeException to report programming errors in the
use of the framework. E.g. trying to set up an expectation to return a
result of the wrong type.
