Testing the API

With our specification defined, we can now use mock tools to test it.

Running a Mock Server

Use the popular tool prism to start a mock server from your OpenAPI spec.

npx @stoplight/prism-cli mock openapi.yaml

Once the server is running, you can test it using curl:

curl http://127.0.0.1:4010/hello

You should see the mock response defined in your spec:

{
  "message": "Hello World"
}
