Running Symfony2 Tests
Running Symfony2 Tests¶
Before submitting a patch for inclusion, you need to run the Symfony2 test suite to check that you have not broken anything.
To run the Symfony2 test suite, install PHPUnit 3.5.11 or later first:
$ pear config-set auto_discover 1 $ pear install pear.phpunit.de/PHPUnit
To run the entire test suite, including tests that depend on external dependencies, Symfony2 needs to be able to autoload them. By default, they are autoloaded from vendor/ under the main root directory (see autoload.php.dist).
The test suite needs the following third-party libraries:
To install them all, run the vendors script:
$ php vendors.php install
Note that the script takes some time to finish.
After installation, you can update the vendors to their latest version with the follow command:
$ php vendors.php update
First, update the vendors (see above).
Then, run the test suite from the Symfony2 root directory with the following command:
The output should display OK. If not, you need to figure out what’s going on and if the tests are broken because of your modifications.
If you want to test a single component type its path after the phpunit command, e.g.:
$ phpunit src/Symfony/Component/Finder/
Run the test suite before applying your modifications to check that they run fine on your configuration.
If you add a new feature, you also need to check the code coverage by using the coverage-html option:
$ phpunit --coverage-html=cov/
Check the code coverage by opening the generated cov/index.html page in a browser.
The code coverage only works if you have XDebug enabled and all dependencies installed.
