assert_generates(expected_path, options, defaults={}, extras={}, message=nil)
Instance Public methods
Asserts that the provided options can be used to generate the provided
path. This is the inverse of assert_recognizes. The
extras parameter is used to tell the request the names and
values of additional request parameters that would be in a query string.
The message parameter allows you to specify a custom error
message for assertion failures.
The defaults parameter is unused.
