Laravel Test Assertions Package

The Laravel Test Assertions package by Shift creator Jason McCreary is a set of helpful assertions for testing Laravel applications. The package provides a trait with useful assertions, Laravel matcher methods, and general test helpers:

use JMac\Testing\Traits\AdditionalAssertions;
 
// Trait assertions
$this->assertActionUsesFormRequest(string $controller, string $method, string $form_request);;
$this->assertActionUsesMiddleware(string $controller, string $method, string|array $middleware);
$this->assertRouteUsesFormRequest(string $routeName, string $formRequest);
$this->assertRouteUsesMiddleware(string $routeName, array $middlewares, bool $exact);
$this->assertValidationRules(array $expected, array $actual);
$this->assertExactValidationRules(array $expected, array $actual);
$this->assertValidationRuleContains($rule, string $class);
$this->assertViewHasNull($key);
$this->createFormRequest(string $class, array $data = []);

The author shared an example of using the freezeNow() helper in a test to freeze time and make assertions.

// Time
$package = Package::factory()->create();
$slug = $this->faker()->slug(2);
 
$this->freezeNow();
 
// Make changes...
$package->slug = $slug;
$package->save();
 
// Assert now
$package->refresh();
$this->assertNow($package->updated_at);

Finally, some matches you can use to determine if a variable is a Model, Collection, or Eloquent Collection instance:

use JMac\Testing\LaravelMatchers;
 
// Matchers
LaravelMatchers::isModel(Model $model = null);
LaravelMatchers::isCollection(Collection $collection = null);
LaravelMatchers::isEloquentCollection(Collection $collection = null);
