Problem: Running a Single PHPUnit Test Method
When using PHPUnit, you might need to run one test method instead of all tests. This approach can save time and resources, especially when fixing bugs or working on a specific feature. Running a single test method helps you test and troubleshoot more efficiently.
Solution: Correct Command Syntax for Running a Single Test Method
PHPUnit Command Structure
The basic command format for running a single test method in PHPUnit is:
phpunit --filter [methodName] [className] [path/to/file.php]The --filter option is important in this command. It lets you specify which test method to run. Without this option, PHPUnit runs all test methods in the file.
Tip: Using Regular Expressions with --filter
You can use regular expressions with the --filter option to run multiple tests that match a pattern. For example, to run all test methods that start with 'test', you can use:
phpunit --filter '/^test/' [path/to/file.php]Executing a Specific Test Method
For PHPUnit version 3.2.8, use this command:
phpunit --filter testSaveAndDrop EscalationGroupTest escalation/EscalationGroupTest.phpThis command tells PHPUnit to run only the testSaveAndDrop method in the EscalationGroupTest class, located in the escalation/EscalationGroupTest.php file.
For newer PHPUnit versions, you can use a simpler command:
phpunit --filter testSaveAndDrop escalation/EscalationGroupTest.phpThis command works the same way, but you don't need to specify the class name separately.
Replace testSaveAndDrop with the name of the test method you want to run, and adjust the file path as needed for your project structure.
