Before submitting a :doc:`patch <patches>` 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 3.6.4 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:
- Doctrine
- Swiftmailer
- Twig
- Monolog
To install them all, use Composer:
Step 1: Get Composer
curl -s http://getcomposer.org/installer | php
Make sure you download composer.phar
in the same folder where
the composer.json
file is located.
Step 2: Install vendors
$ php composer.phar --dev install
Note
Note that the script takes some time to finish.
Note
If you don't have curl
installed, you can also just download the installer
file manually at http://getcomposer.org/installer. Place this file into your
project and then run:
$ php installer
$ php composer.phar --dev install
After installation, you can update the vendors to their latest version with the follow command:
$ php composer.phar --dev update
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.
Tip
If you want to test a single component type its path after the phpunit command, e.g.:
$ phpunit src/Symfony/Component/Finder/
Tip
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.
Tip
The code coverage only works if you have XDebug enabled and all dependencies installed.
