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.

PHPUnit

To run the Symfony2 test suite, install PHPUnit 3.5.11 or later first:

$ pear channel-discover pear.phpunit.de
$ pear channel-discover components.ez.no
$ pear channel-discover pear.symfony-project.com
$ pear install phpunit/PHPUnit

Dependencies (optional)

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:

  • Doctrine
  • Swiftmailer
  • Twig
  • Monolog

To install them all, run the vendors script:

$ php vendors.php install

注解

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

Running

First, update the vendors (see above).

Then, run the test suite from the Symfony2 root directory with the following command:

$ phpunit

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.

小技巧

Run the test suite before applying your modifications to check that they run fine on your configuration.

Code Coverage

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.

小技巧

The code coverage only works if you have XDebug enabled and all dependencies installed.
