Rack::MockRequest helps testing your Rack application without actually using HTTP.
After performing a request on a URL with get/post/put/delete, it returns a MockResponse with useful helper methods for effective testing.
You can pass a hash with additional configuration to the get/post/put/delete.
:input: | A String or IO-like to be used as rack.input. |
:fatal: | Raise a FatalWarning if the app writes to rack.errors. |
:lint: | If true, wrap the application in a Rack::Lint. |
Return the Rack environment used for a request to uri.
