PHPUnit in Laravel doesn't run when adding folders

Question

I wanted to break my testing into their M, V, C folders. So I have:

/tests
    /models
    /views
    /controllers
    TestCase.php

As an example, I have a UsersControllerTest.php inside /controllers:

class UsersControllerTest extends TestCase {

    public function testSimple()
    {
        $this->assertTrue(true);
    }

}

When I run phpunit, all I get is Configuration read from PATH_TO_phpunit.xml. The problem arises when I add a test file inside a folder. If I move that test file to the root /tests folder, then everything works fine.

I tried to edit the phpunit.xml file to include:

<testsuites>
    <testsuite name="Application Test Suite">
        <directory>./app/tests</directory>
        <directory>./app/tests/controllers</directory>
    </testsuite>
</testsuites>

But it still didn't work

Answer 1

Solution was much simpler that I anticipated. All you have to do is add an asterix, *, to the end of the directory path inside phpunit.xml file:

<testsuites>
    <testsuite name="Application Test Suite">
        <directory>./app/tests/*</directory>
    </testsuite>
</testsuites>
