serverless-http-invoker

Locally invoke Serverless functions via their HTTP event as specified in Serverless.yml.

It makes it easy to test not only your handler logic, but also ensures that you have your http events setup properly in serverless.yml without deploying.

Usage / Quick Start

Use it in tests of Serverless functions to test your HTTP endpoints along with the handler code. For example, you can write the following to test a Serverless function:

it('should invoke simple path', function () {
  let response = invoker.invoke('GET api/hello')
  return expect(response).to.eventually.have.property('statusCode', 200)
})

The test above is a test of a Serverless function defined in a Serverless.yml as follows:

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          path: api/hello
          method: get
