API Testing

Validate APIs and backend services directly from the TestFirst Editor using natural language test steps.

API testing allows you to send requests, validate responses, extract data, and verify integrations without interacting with a user interface. API tests can be executed independently or combined with other automation types as part of an end-to-end testing workflow.

Example

Scenario: Get user details
  Given GET HTTP request
  When I send request to "{Endpoints.Users}"
  Then response status should be 200

API testing is fully integrated into TestFirst's Unified Test Automation approach, allowing API tests to work seamlessly with web, mobile, and other automation types within the same test case.
