What it does
ReadyAPI is SmartBear's commercial API-testing suite for creating and running functional, security and performance tests. Its documentation supports importing API definitions and organizing services such as REST, GraphQL, Kafka, SOAP and XML-RPC in projects. Testers can add assertions, run test cases, simulate dependencies with virtual services and use test-runner utilities to automate checks in CI workflows.
Import an API and validate its responses
ReadyAPI's quick-start guide begins with an API definition such as OpenAPI, Swagger, WSDL or a Postman collection. Import it into a project, create a test suite and test case, then add assertions for response status, JSON or XML structure, or schema validity. Run the case and inspect the results in the test runner. The API workspace can also hold REST, GraphQL, Kafka, SOAP and XML-RPC services.
The product extends beyond functional assertions. Its documentation covers security tests, performance tests and virtual services that define mock responses and latency for unavailable or costly dependencies. Runner utilities and CI guidance support executing tests from build workflows, while the product page lists Jenkins, TeamCity and Azure DevOps integrations.
ReadyAPI is aimed at API quality rather than browser UI testing. The public product page offers a free trial and demo; the accessed pricing page names API test packages but does not publish complete prices or trial duration. This entry covers ReadyAPI's commercial suite, not the separately listed SoapUI Open Source project, and not SmartBear's LoadNinja or QMetry products.
Strengths
- The quick start accepts common API definitions and guides users from import to suites, cases, assertions and results.
- Documentation covers REST, GraphQL, Kafka, SOAP and XML-RPC services.
- Functional, security and performance testing can be paired with virtual services for controlled dependency behavior.
- Test-runner utilities and CI integrations support automating API checks in build pipelines.
Watch out for
- ReadyAPI is specialized for API testing; it does not replace a browser-based UI test suite.
- A useful first test needs an API definition or service endpoint plus expected response behavior to assert.
Best for
- QA teams validating REST, SOAP or other service APIs across functional and security scenarios.
- Developers testing API performance and latency before release.
- Teams that need mock services to continue testing while downstream APIs are unavailable.
