FAQPage Schema
How do I automate API contract testing for REST endpoints?

API contract testing is automated by running a test runner like Vitest against a defined contract to verify response schemas, status codes, and error formats. This validates REST API compliance and generates structured, traceable reports.

What is API contract testing and how does it validate HTTP endpoints?

API contract testing validates HTTP endpoints by automatically checking that responses match a defined business contract. It verifies schemas, status codes, and error formats, reducing manual QA effort across multiple API interactions.

Do I need a specific test runner to run API smoke tests and validation?

You need a test runner like Vitest and a defined API contract to run smoke tests and validation. This setup allows you to verify endpoint authentication, pagination, and error handling across any REST or HTTP API.

Can I use API contract tests for authentication and pagination across multiple endpoints?

Yes, API contract tests can validate authentication and pagination across multiple endpoints. The testing process verifies schemas and error formats for any REST API, ensuring comprehensive compliance and standardized output templates.

What is the best way to generate CI-friendly reports for API contract tests?

The best way to generate CI-friendly reports for API contract tests is to run automated scripts that verify schemas and status codes. This produces structured outputs for easy CI integration and compliance traceability.

Does API contract testing work with curl examples and automated scripts?

Yes, API contract testing supports curl examples and automated scripts to verify endpoint compliance. It validates schemas and error formats against a defined contract, outputting standardized templates for traceability.
