I have developed some bundles, and I want to add tests for them. So, I have created the file Tests/Service/EmailServiceTest.php that contains one test.
I have installed PHPUnit using sudo apt install phpunit on my Ubuntu computer, but when I cd to my bundle's folder and run phpunit I have the following error:
c975L\EmailBundle\Tests\Service\EmailServiceTest::testCreateEmailObject Error: Class 'c975L\EmailBundle\Service\EmailService' not found
It looks like the autoloader can't find the class, even if declared at the top with use.
How do we test a Symfony Bundle with PHPUnit?
It is a good idea to install phpunit on a per project basis, as version differences could come up if you have multiple projects.
(1) composer require phpunit/phpunit --dev
I saw some solutions over the web that requires to create a bootstrap.php with autoload but even with this, it doesn't work...
You can use composer's autoloader as a bootstrap. A custom bootstrap might come in handy in some cases, but not necessary.
(2) Create a phpunit.xml.dist file, something like this (your current one does not specify a bootstrap):
<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="./vendor/autoload.php">
<testsuites>
<testsuite name="MyBundle test suite">
<directory suffix="Test.php">./Tests</directory>
</testsuite>
</testsuites>
<filter>
<whitelist>
<directory>./</directory>
<exclude>
<directory>./Resources</directory>
<directory>./Tests</directory>
<directory>./vendor</directory>
</exclude>
</whitelist>
</filter>
</phpunit>
Also check out vendor/bin/phpunit --generate-configuration which is nice.
(3) Run vendor/bin/phpunit
It should find the config file automatically, but you can also specify it with the --configuration option
