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.
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 Serverless.yml as follows:
functions:
hello:
handler: handler.hello
events:
- http:
path: api/hello
method: get
Many more examples and exaustive list of what is supported in the tests. Some additional real-world examples are demonstrated in the sheetmonkey-server project. See PluginsHandler.js and PluginAuthHandler.js among others.
