api-testing

OpenAPI-driven API testing with Schemathesis for schema validation, fuzzing, and CI reporting.

Overview

Schemathesis reads OpenAPI schemas (local or remote) and generates tests that validate API behavior. It supports authentication, different phases (examples and fuzzing), concurrency, and test reports.

When to Use

• You already have OpenAPI specs and want coverage
• You need fuzzing or schema-driven tests
• You want CI-friendly reports (JUnit)

When Not to Use

• No schema exists (generate one first)
• You need UI/browser tests
