This module allows you to run functional tests inside Slim 3 Microframework without HTTP calls, so tests will be much faster and debug could be easier.

Inspiration comes from herloct/codeception-slim-module library.

• php: ^7.2 || ^8.0
• slim/slim: ^3.1
• codeception/codeception: ^4.0

If you don't know Codeception, please check Quickstart Guide first.

If you already have Codeception installed in your Slim application, you can add codeception-slim-module with a single composer command.

composer require --dev docler-labs/codeception-slim-module

Example (test/suite/functional.suite.yml)

modules:
  enabled:
    - DoclerLabs\CodeceptionSlimModule\Module\Slim:
        application: path/to/application.php
    - REST:
        depends: DoclerLabs\CodeceptionSlimModule\Module\Slim

The application property is a relative path to file which returns your Slim\App instance. Here is the minimum application.php content:

require __DIR__ . '/vendor/autoload.php';

use Slim\App;

$app = new App();

// Add routes and middlewares here.

return $app;

class UserCest
{
    public function getUserReturnsWithEmail(FunctionalTester $I): void
    {
        $I->haveHttpHeader('Content-Type', 'application/json');

        $I->sendGET('/users/John');

        $I->seeResponseCodeIs(200);
        $I->seeResponseContainsJson(
            [
                'email' => 'john.doe@example.com',
            ]
        );
    }
}
