Codeception skill

Skill Pyfagorass/bookofspells/skills/lambdatest/codeception-skill

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".From its SKILL.md

Codeception Testing Skill

Core Patterns

Acceptance Test (Cest)

<?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)

// 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
// 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 Config (acceptance.suite.yml)

actor: AcceptanceTester
modules:
  enabled:
    - WebDriver:
        url: 'http://localhost:3000'
        host: 'hub.lambdatest.com'
        port: 80
        browser: chrome
        capabilities:
