Typically, with function-based tests, you create a test file and pass the file name to the

runtests function without explicitly creating a suite of Test objects. However, if you

create an explicit test suite, additional features are available in function-based testing.

These features include:

• Test logging and verbosity


• Test selection


• Plugins to customize the test runner

For additional functionality, consider using “Class-Based Unit Tests”.

Fixtures for Setup and Teardown Code

When writing tests, use the TestCase.applyFixture method to handle setup and

teardown code for actions such as:

• Changing the current working folder


• Adding a folder to the path


• Creating a temporary folder


• Suppressing the display of warnings

These fixtures take the place of manually coding the actions in the setupOnce,

teardownOnce, setup, and teardown functions of your function-based test.
