Automate browsers, desktop apps, and mobile web with the same syntax you already know. Built-in waits, retries, and visual testing — no flaky tests.
Feature: Login and Dashboard
Scenario: User logs in and sees dashboard
Given driver 'https://app.example.com/login'
# Fill login form
And input('#email', 'user@test.com')
And input('#password', 'secure123')
When click('{^}Sign In')
# Verify dashboard loaded
Then waitFor('.dashboard')
And match text('.welcome') contains 'Hello'
# Take a screenshot for visual testing
And screenshot()
Features
Karate's UI automation is designed for reliability. No flaky selectors, no manual waits, no test maintenance nightmares.
Run the same tests across Chrome, Firefox, Safari, and Edge. Powered by the WebDriver protocol with zero config changes.
Built-in screenshot comparison for visual regression testing. Catch layout shifts and styling bugs before they reach production.
Test responsive layouts and mobile web apps with device emulation. Same syntax, same framework — just a different viewport.
Automate Windows and macOS desktop applications. Use image-based locators or native accessibility selectors.
Automatic retry-until-success for element interactions. No more Thread.sleep() or explicit waits cluttering your tests.
Mix API calls and browser interactions in the same scenario. Set up test data via API, then verify the UI — all in one file.
The Karate Advantage
No other framework lets you combine API calls and browser automation in a single test file. Create data via API, then verify it renders correctly in the UI.
Set up test data with API calls — no database fixtures needed
Verify end-to-end workflows across the full stack
Clean up after tests with API teardown — no leftover state
Feature: End-to-End Order Flow
Scenario: Create order via API, verify in UI
# Step 1: Create order via API
Given url 'https://api.shop.com/orders'
And request { item: 'Laptop', qty: 1 }
When method post
Then status 201
* def orderId = response.id
# Step 2: Verify in browser
Given driver 'https://shop.com/orders'
And waitFor('{div}' + orderId)
Then match text('.status') == 'Pending'
