Class Rack::MockRequest
In: lib/rack/mock.rb
Parent: Object

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.

Methods

delete   env_for   get   new   post   put   request
