- Allow for different user levels by checking the CurrentUser variable - Allow for other URL parameters other than the search parameters -- This is needed on some controllers such as the comments controller - Allow for delayed execution of lambda functions for item input -- This is because the updated_at field isn't correct at the time that the input gets sent to the function -- This prevented the right order from being tested

# responds to a search correctly. See https://thoughtbot.com/blog/shoulda-matchers.

# Usage:
|
|
#
|
|
# # Tests that `/tags.json?search[name]=touhou` returns the `touhou` tag.
|
|
# subject { TagsController }
|
|
# setup { @touhou = create(:tag, name: "touhou") }
|
|
# should respond_to_search(name: "touhou").with { @touhou }
|
|
