README

This package contains some PHPUnit test cases.

Prerequisite

The test runner requires a vanilla Magento 2 installation. To run test suite it's necessary to set the environment variable N98_MAGERUN2_TEST_MAGENTO_ROOT with the root path to the installation.

All unit tests run against this installation. Please don't use any production environment!

Test Module Commands

Example Test Case:

<?php

namespace Acme\Example\Command;

use N98\Magento\Command\PHPUnit\TestCase;
use Symfony\Component\Console\Tester\CommandTester;

class FooCommandTest extends TestCase
{
    /**
     * @test
     */
    public function testOutput()
    {
        /**
         * Load module config for unit test. In this case the relative
         * path from current test case.
         */
        $this->loadConfigFile(__DIR__ . '/../../n98-magerun2.yaml');

        /**
         * Test if command could be found
         */
        $command = $this->getApplication()->find('foo');

        /**
         * Call command
         */
        $commandTester = new CommandTester($command);
        $commandTester->execute(
            [
            ]
        );
    }
}

Test dev:console Commands

Code-Generating Command

Create a reference file which contains the content of the code generator. In the following test case the file is place in "DIR /_files/ExampleSomething.php".

The method mockWriterFileWriteFileAssertion of the TestCase class mocks the module writer and compares the output against the reference file.

<?php

namespace Acme\Example\Command\CodeGenerator;

use N98\Magento\Command\Developer\Console\PHPUnit\TestCase;

class MakeSomethingCommandTest extends TestCase
{
    /**
     * @test
     */
    public function testGenerator()
    {
        $command = new MakeSomethingCommand();

        $commandTester = $this->createCommandTester($command);
        $command->setCurrentModuleName('Acme_Example');

        $writerMock = $this->mockWriterFileWriteFileAssertion(
            __DIR__ . '/_files/ExampleSomething.php'
        );

        $command->setCurrentModuleDirectoryWriter($writerMock);
        $commandTester->execute([
            /* pass your parameters */
        ]);
    }
}
