如何在 Symfony 中扩展 WebTestCase

Question

I want to write functional tests in symfony but I am unable to over-ride createKernel method of WebTestCase. Our application integrated symfony by using an HttpKernel like this :

$kernel = new HttpKernel($dispatcher, $controllerResolver, new 
RequestStack(), $argumentResolver);

$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();

$kernel->terminate($request, $response);

I tried returning this kernel from over-ridden createKernel method but it doesn't have some methods(like getContainer() ) which gives error later on. How can I create my own kernel for WebTestCase?

Answer 1

please see documentation testing (symfony docs)

To run your functional tests, the WebTestCase class needs to know which is the application kernel to bootstrap it. The kernel class is usually defined in the KERNEL_CLASS environment variable (included in the default phpunit.xml.dist file provided by Symfony):

<?xml version="1.0" charset="utf-8" ?>
<phpunit>
    <php>
        <!-- the value is the FQCN of the application kernel -->
        <env name="KERNEL_CLASS" value="App\Kernel" />
    </php>
    <!-- ... -->
</phpunit>

Also, you have phpunit runnable in your bin directory and phpunit.xml.dist file in app directory. usually you can run tests by bin/phpunit -c app path_to_the_tests
