Introduction
Welcome
Imposter is a mock server for REST APIs, OpenAPI (and Swagger) specifications, SOAP web services (and WSDL files), Salesforce and HBase APIs.
- Run standalone mock servers in Docker, Kubernetes, AWS Lambda or on the JVM.
- Embed mocks within your tests (JVM or Node.js) to remove external dependencies.
- Script dynamic responses using JavaScript, Groovy or Java.
- Capture data from requests, then store it or return a templated response.
- Proxy an existing endpoint to replay its responses as a mock.
