Running Unit Tests
From Joomla! Documentation
It has been suggested that this article or section be merged with Running_Automated_Tests_for_the_Joomla_CMS#Running_Unit_Tests. (Discuss). Proposed since 21 months ago.
Running the Entire Test Suite
The entire test suite can be run by simply entering the test directory and typing phpunit:
cd /path/to/joomla/tests/unit phpunit
Specifying a Directory of Tests to Run
You can run a subset of tests by specifying the directory path of the tests that you want to run.
Will run all of the tests in the specified directory and any subdirectory.
Using the --filter Parameter to Run Certain Tests
The --filter parameter allows you to run a specific subset of the entire test suite. The --filter parameter takes a regular expression that can be used to filter out tests.
phpunit --filter JForm
Will scan through the suite directory and run tests that contain JForm in the class name or in the method name.
