Codeception Testing Skill

Description

--- name: codeception-skill description: > Generates Codeception tests in PHP covering acceptance, functional, and unit testing. BDD-style with Actor pattern. Use when user mentions "Codeception", "$I->amOnPage", "$I->see", "Cest". Triggers on: "Codeception", "$I->amOnPage", "AcceptanceTester", "Codeception PHP", "Cest". languages: - PHP category: e2e-testing license: MIT metadata: author: TestMu AI version: "1.0" --- # Codeception Testing Skill ## Core Patterns ### Acceptance Test (Cest) ```php <?php // tests/Acceptance/LoginCest.php class LoginCest { public function _before(AcceptanceTester $I) { $I->amOnPage('/login'); } public function loginWithValidCredentials(AcceptanceTester $I) { $I->fillField('email', '[email protected]'); $I->fillField('password', 'password123'); $I->click('Login'); $I->see('Dashboard'); $I->seeInCurrentUrl('/dashboard'); $I->seeElement('.welcome-message'); } public function loginWithInvalidCredentials(AcceptanceTester $I) { $I->fillField('email', '[email protected]'); $I->fillField('password', 'wrong'); $I->click('Login'); $I->see('Invalid credentials'); $I->seeInCurrentUrl('/login'); } } ``` ### Actor Methods (AcceptanceTester $I) ```php // Navigation $I->amOnPage('/path'); $I->click('Button Text'); $I->click('#id'); $I->click(['xpath' => '//button']); // Forms $I->fillField('Name or Label', 'value'); $I->selectOption('Select', 'Option'); $I->checkOption('Checkbox'); $I->uncheckOption('Checkbox'); $I->attachFile('Upload', 'file.txt'); $I->submitForm('#form', ['email' => '[email protected]']); // Assertions $I->see('Text'); $I->dontSee('Text'); $I->seeElement('#id'); $I->dontSeeElement('.error'); $I->seeInField('email', '[email protected]'); $I->seeInCurrentUrl('/dashboard'); $I->seeInTitle('Page Title'); $I->seeCheckboxIsChecked('#agree'); $I->seeNumberOfElements('li', 5); // Grabbers $text = $I->grabTextFrom('.element'); $attr = $I->grabAttributeFrom('#link', 'href'); $value = $I->grabValueFrom('#input'); ``` ### Page Objects (Step Objects) ```php <?php // tests/_support/Page/Login.php namespace Page; class Login { public static $url = '/login'; public static $emailField = '#email'; public static $passwordField = '#password'; public static $loginButton = 'button[type="submit"]'; protected $I; public function __construct(\AcceptanceTester $I) { $this->I = $I; } public function login(string $email, string $password): void { $this->I->amOnPage(self::$url); $this->I->fillField(self::$emailField, $email); $this->I->fillField(self::$passwordField, $password); $this->I->click(self::$loginButton); } } ``` ### Cloud (TestMu AI) Full setup: [reference/cloud-integration.md](reference/cloud-integration.md).
