Instance Method Details

#expect_request_invalid(message, opts = {}, &additional_examples) ⇒ Object

This macro expects the following to be defined: let(:valid_payload) { request_payload that would succeed }

You then pass a override hash and the expected response code, usually a 400 Bad Request or 422 Unprocessible Entity

In overrides, if you pass a callable object such as a lambda or a proc, then it will be called at test time before merging into the request payload.

Example:

overrides: { apple: -> { tree.apples.sample } }
