To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaboratorstub with a simple return value
Use the stub
method on a test double or a real object to tell the object to
return a value (or values) in response to a given message. If the message is
never received, nothing happens.
- Scenarios
-
- simple stub with no return value
-
- Given
-
a file named "example_spec.rb" with:
describe "a simple stub with no return value specified" do let(:receiver) { double("receiver") } it "returns nil" do receiver.stub(:message) receiver.message.should be(nil) end it "quietly carries on when not called" do receiver.stub(:message) end end
- When
- I run "rspec example_spec.rb"
- Then
- the output should contain "0 failures"
- single return value
