Core Patterns
Basic Test
module.exports = {
'Login with valid credentials': function(browser) {
browser
.url('http://localhost:3000/login')
.waitForElementVisible('#email', 5000)
.setValue('#email', 'user@test.com')
.setValue('#password', 'password123')
.click('button[type="submit"]')
.waitForElementVisible('.dashboard', 10000)
.assert.containsText('.welcome', 'Welcome')
.assert.urlContains('/dashboard')
.end();
},
'Login with invalid credentials shows error': function(browser) {
browser
.url('http://localhost:3000/login')
.waitForElementVisible('#email', 5000)
.setValue('#email', 'wrong@test.com')
.setValue('#password', 'wrong')
.click('button[type="submit"]')
.waitForElementVisible('.error-message', 5000)
.assert.containsText('.error-message', 'Invalid credentials')
.end();
}
};
Page Objects
// pages/loginPage.js
module.exports = {
url: '/login',
elements: {
emailInput: '#email',
passwordInput: '#password',
loginButton: 'button[type="submit"]',
errorMessage: '.error-message',
},
commands: [{
login(email, password) {
return this
.setValue('@emailInput', email)
.setValue('@passwordInput', password)
.click('@loginButton');
}
}]
};
// tests/loginTest.js
module.exports = {
'Login test': function(browser) {
const login = browser.page.loginPage();
login.navigate()
.login('user@test.com', 'password123');
browser.assert.urlContains('/dashboard');
}
};
Assertions
browser.assert.visible(selector);
browser.assert.not.visible(selector);
browser.assert.containsText(selector, 'text');
browser.assert.urlContains('/path');
browser.assert.titleContains('Page Title');
browser.assert.elementPresent(selector);
browser.assert.cssClassPresent(selector, 'active');
browser.assert.value('#input', 'expected');
browser.assert.attributeEquals(selector, 'href', '/link');
browser.assert.elementsCount('li', 5);
