Pest

Instructions

• Use php artisan make:test --pest {name}.
• Pest tests look and behave like this:

<code-snippet name="Basic Pest Test Example" lang="php"> it('is true', function () { expect(true)->toBeTrue(); }); </code-snippet>

Examples

Pest Assertions

• When asserting status codes on a response, use the specific method like assertForbidden and assertNotFound instead of using assertStatus(403) or similar, e.g.:

<code-snippet name="Pest Example Asserting postJson Response" lang="php"> it('returns all', function () { $response = $this->postJson('/api/docs', []); $response->assertSuccessful(); }); </code-snippet>

Mocking

• Mocking can be very helpful when appropriate.
• When mocking, you can use the Pest\Laravel\mock Pest function, but always import it via use function Pest\Laravel\mock; before using it. Alternatively, you can use $this->mock() if existing tests do.
• You can also create partial mocks using the same import or self method.

Datasets

• Use datasets in Pest to simplify tests which have a lot of duplicated data. This is often the case when testing validation rules, so consider going with this solution when writing tests for validation rules.

<code-snippet name="Pest Dataset Example" lang="php"> it('has emails', function (string $email) { expect($email)->not->toBeEmpty(); })->with([ 'james' => '[email protected]', 'taylor' => '[email protected]', ]); </code-snippet>

Pest 4

• Pest v4 is a huge upgrade to Pest and offers: browser testing, smoke testing, visual regression testing, test sharding, and faster type coverage.
• Browser testing is incredibly powerful and useful for this project.
• Browser tests should live in tests/Browser/.
