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)'statusCode', 200)

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

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

Some of the more common use cases are demonstrated in the basic tests at the basic test cases. An exhaustive list of what is supported in Some of the more common use cases are demonstrated in the basic tests at the comprehensive test cases.

Prerequisites / Usage Requirements

Requires Node.js latest, LTS, and v10 (tested).

If you need Node.js v6.x - v9.x support you can use serverless-http-invoker@0.8.6.
