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 collaboratorexpect a message
Use should_receive() to set an expectation that a receiver should receive a
message before the example is completed.
- Scenarios
-
- expect a message
-
- Given
-
a file named "spec/account_spec.rb" with:
require "account" describe Account do context "when closed" do it "logs an account closed message" do logger = double("logger") account = Account.new account.logger = logger logger.should_receive(:account_closed) account.close end end end
- And
-
a file named "lib/account.rb" with:
class Account attr_accessor :logger def close logger.account_closed end end
- When
-
I run
rspec spec/account_spec.rb
- Then
- the output should contain "1 example, 0 failures"
- expect a message with an argument

- And
-
a file named "lib/account.rb" with:
class Account attr_accessor :logger def close logger.account_closed(self) end end
- When
-
I run
rspec spec/account_spec.rb
- Then
- the output should contain "1 example, 0 failures"
- provide a return value
-
- Given
-
a file named "message_expectation_spec.rb" with:
describe "a message expectation" do context "with a return value" do context "specified in a block" do it "returns the specified value" do receiver = double("receiver") receiver.should_receive(:message) { :return_value } receiver.message.should eq(:return_value) end end context "specified with and_return" do it "returns the specified value" do receiver = double("receiver") receiver.should_receive(:message).and_return(:return_value) receiver.message.should eq(:return_value) end end end end
- When
-
I run
rspec message_expectation_spec.rb
- Then
- the output should contain "2 examples, 0 failures"
