Question 1

How to get started with Karate for API testing?

Accepted Answer

Karate provides comprehensive documentation at docs.karatelabs.io with examples for REST, GraphQL, and SOAP APIs. You can set it up using Maven or Gradle dependencies and write tests in a BDD-style syntax that mimics natural language, making it easy to create assertions and validations.

Question 2

Karate vs Selenium for UI automation?

Accepted Answer

Karate includes built-in browser automation capabilities, but it's designed as part of a unified framework. Selenium is more established with a larger ecosystem for UI testing, so if UI testing is your primary focus, Selenium might be better, but Karate offers integration with API and performance testing in one tool.

Question 3

Can Karate handle performance testing for high-load scenarios?

Accepted Answer

Yes, Karate has integrated performance testing features, but for very high-scale or distributed load testing, dedicated tools like JMeter or Gatling might offer more advanced options and scalability, as Karate's approach is more streamlined within its unified framework.

Question 4

How to mock services in Karate?

Accepted Answer

Karate provides built-in mocking capabilities where you can define mock servers directly in your test scripts using simple syntax. The documentation includes examples for creating stubs and virtualizing services, allowing you to simulate dependencies without external tools.

Question 5

Is Karate suitable for testing GraphQL APIs?

Accepted Answer

Absolutely, Karate supports GraphQL testing with built-in assertions and syntax for writing queries and mutations. It handles GraphQL requests similarly to REST, making it a viable option for teams working with modern web services.

Question 6

What are the main differences between Karate and Cucumber?

Accepted Answer

Both use BDD syntax, but Karate is a complete testing framework with built-in HTTP client, mocks, and performance testing, whereas Cucumber is primarily a BDD tool that requires additional libraries for API or UI testing. Karate reduces setup by integrating everything into one package.
