Do you want to test a specific folder in PHPunit? When I do this, I usually run the command very often. I have found a way to implement this feature more easily.

Go into your phpunit.xml file and search for the <testsuites> brackets.

Inside of this, place a new testsuite. You’ll want to be sure to include the name and the path. Like so…

<testsuite name="Email">
    <directory suffix="Test.php">./tests/Unit/Emails</directory>

Now, on the command line, run the command (and replace Email with whatever your testsuite name is).

phpunit --testsuite Email

Now you can run a collections of tests in a folder, and have it be a little bit easier in terms of remembering and typing out the directory each time :)
