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 collaboratorMethod stubs
Stub return values
obj.stub(:message) { :value }
obj.stub(:message => :value)
obj.stub(:message).and_return(:value)
These forms are somewhat interchangeable. The difference is that the block
contents are evaluated lazily when the obj receives the message message,
whereas the others are evaluated as they are read.
Fake implementation
obj.stub(:message) do |arg1, arg2|
# set expectations about the args in this block
# and/or set a return value
end
Raising/Throwing
obj.stub(:message).and_raise("this error")
obj.stub(:message).and_throw(:this_symbol)
You can also use the block format, for consistency with other stubs:
obj.stub(:message) { raise "this error" }
obj.stub(:message) { throw :this_symbol }
Argument constraints
Explicit arguments
obj.stub(:message).with('an argument') { ... }
obj.stub(:message).with('more_than', 'one_argument') { ... }
Argument matchers
obj.stub(:message).with(anything()) { ... }
obj.stub(:message).with(an_instance_of(Money)) { ... }
obj.stub(:message).with(hash_including(:a => 'b')) { ... }
Regular expressions
obj.stub(:message).with(/abc/) { ... }
