Pest Grouping Tests

Pest allows to set groups for tests. Group can be set for a folder, a file, or a test. Multiple groups can also be assigned.

The group() function is used to add a group. Here is an example of a specific test.

tests/Feature/ProductsTest.php:

test('api product store successful', function () {
    $product = [
        'name' => 'Product 1',
        'price' => 123
    ];
 
    postJson('/api/products', $product)
        ->assertStatus(201)
        ->assertJson($product);
})->group('api'); 
 
test('api product invalid store returns error', function () {
    $product = [
        'name' => '',
        'price' => 123
    ];
 
    postJson('/api/products', $product)
        ->assertStatus(422);
})->group('api'); 

When running tests, the flag --group should be used with the group name, to filter tests by a group.

We added API tests to the same ProductsTest file in this course. But, if we moved all API tests to the tests/Feature/Api folder, we could...
