Feature/Unit Tests: Make them Work

The next thing I usually check is whether the project has tests. It means I can try to modify the code and run the tests to check if I didn't break anything.

And we do have some tests here:

But when I try to run them, I get an error:

Configuring Unit/Feature Tests

Well, yeah, I don't see the tests/Unit folder. And don't get me wrong: it's totally fine NOT to have Unit tests, staying only with Feature tests. But the default Laravel comes with the example Unit test:

tests/Unit/ExampleTest.php:

namespace Tests\Unit;
 
use PHPUnit\Framework\TestCase;
 
class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     */
    public function test_that_true_is_true(): void
    {
        $this->assertTrue(true);
    }
}

In this case, the code author has deleted that example test with the full folder of tests/Unit. It may be fine, but the problem is that testing is still configured to run tests from the tests/Unit folder, which doesn't exist anymore:

phpunit.xml

<testsuites>
    <testsuite name="Unit">
        <directory>tests/Unit</directory>
    </testsuite>
    <testsuite name="Feature">
        <directory>tests/Feature</directory>
    </testsuite>
</testsuites>

So, we have two choices here:

• Either create a tests/Unit empty folder
• Or, specify in...
