Symfony2 phpunit run tests on different environment - symfony

Question

I'm testing email sending in my symfony2 application, I have custom environment that is properly set with email settings and it's able to actually sent emails. I've created environment test_emails and I want to run my phpunit tests with it.
phpunit doesn't seem to have this functionality, so my only option is probably create custom bootstrap file, but I can't find anywhere how to do it.

Answer 1

The doc about Environments says:
The test environment is used when writing functional tests and is not accessible in the browser directly via a front controller. In other words, unlike the other environments, there is no app_test.php front controller file.
So when testing emails you're supposed to use functional test which is well described in How to Test that an Email is Sent in a Functional Test.
If you want to write a custom bootstrap with some simple logic see: How to Customize the Bootstrap Process before Running Tests
Maybe you can actually customize what environment the test harness is using by creating a custom test case that boots the kernel just like here How can I test a service in symfony2? and then passing an array of options to bootKernel() method. See:
https://github.com/symfony/framework-bundle/blob/master/Test/KernelTestCase.php#L141
https://github.com/symfony/framework-bundle/blob/master/Test/KernelTestCase.php#L168

Answer 2

If your using Symfonys WebtestCase you can set the environment as option:
$client = static::createClient(array('environment' => 'test-emails'));

Answer 3

I've ended up creating command that sends all emails I wanted and I can easily switch between environments.
Example:
php app/console app:emails:test-emails --env=dev

Answer 4

Use different phpunit.xml configuration files for each environment.
.
├── phpunit_test_emails.xml
└── phpunit_other_env.xml
Run the tests with specific configuration:
$ phpunit -c phpunit_test_emails.xml
You can set different PHP configurations in the XML configuration file.
You create a custom bootstrap via the bootstrap attribute where additional initialisations can be done if needed.
<phpunit bootstrap="test/bootstrap.php">
<!-- ... -->
<php>
<includePath>.</includePath>
<ini name="foo" value="bar"/>
<const name="foo" value="bar"/>
<var name="foo" value="bar"/>
<env name="foo" value="bar"/>
<post name="foo" value="bar"/>
<get name="foo" value="bar"/>
<cookie name="foo" value="bar"/>
<server name="foo" value="bar"/>
<files name="foo" value="bar"/>
<request name="foo" value="bar"/>
</php>
</phpunit>
See the PHPUnit Manual for more details.
