Reliable, scriptable and extensible mock server for general REST APIs, OpenAPI (aka Swagger) specifications, Salesforce and HBase APIs.
Scripting support for both JavaScript or Groovy/Java.
Use Imposter to:
- run standalone mocks in place of real systems
- turn a OpenAPI/Swagger file into a mock API for testing or QA
- quickly set up a temporary API for your mobile/web client teams whilst the real API is being built
- decouple your integration tests from the cloud/various back-end systems and take control of your dependencies
Provide mock responses using static files or customise behaviour using JavaScript or Java/Groovy. Power users can write their own plugins in a JVM language of their choice.
The quickest way to get up and running is to use our free cloud-hosted version at https://www.remotemock.io
Imposter uses plugins to control its behaviour and provide specialised mocks:
- REST - Mocks RESTful or plain HTTP APIs.
- OpenAPI (aka Swagger) - Support for OpenAPI (aka Swagger) API specifications.
- HBase - Basic HBase mock implementation.
- SFDC (Salesforce) plugin - Basic Salesforce mock implementation.
You can also create your own plugins, using a JVM language of your choice.
Let's assume your configuration is in a folder named config.
Docker example:
docker run -ti -p 8080:8080 \
-v $(pwd)/config:/opt/imposter/config \
outofcoffee/imposter-rest
Standalone Java example:
java -jar distro/rest/build/libs/imposter-rest.jar \
--configDir ./config
Your mock server is now running!
This example starts a mock server using the simple
REST plugin, serving responses based on the configuration files
inside the config folder. You can hit the URL
http://localhost:8080/example to see the mock response.
