Feature: Spy on a stubbed method on a pure mock
You can use `have_received` to verify that a stubbed method was invoked,
rather than setting an expectation for it to be invoked beforehand.
Scenario: verify a stubbed method
Given a file named "verified_spy_spec.rb" with:
"""ruby
describe "have_received" do
it "passes when the expectation is met" do
invitation = double('invitation', :deliver => true)
invitation.deliver
invitation.should have_received(:deliver)
end
end
"""
When I run `rspec verified_spy_spec.rb`
Then the examples should all pass
Scenario: verify a stubbed method with message expectations
Given a file named "verified_message_expectations_spec.rb" with:
"""ruby
describe "have_received" do
it "passes when the expectation is met" do
invitation = double('invitation', :deliver => true)
2.times { invitation.deliver(:expected, :arguments) }
invitation.should have_received(:deliver).
with(:expected, :arguments).
twice
end
end
"""
When I run `rspec verified_message_expectations_spec.rb`
Then the examples should all pass
Scenario: fail to verify a stubbed method
Given a file named "failed_spy_spec.rb" with:
"""ruby
describe "have_received" do
it "fails when the expectation is not met" do
invitation = double('invitation', :deliver => true)
invitation.should have_received(:deliver)
end
end
"""
When I run `rspec failed_spy_spec.rb`
Then the output should contain "expected: 1 time"
And the output should contain "received: 0 times"
Scenario: fail to verify message expectations
Given a file named "failed_message_expectations_spec.rb" with:
"""ruby
describe "have_received" do
it "fails when the arguments are different" do
invitation = double('invitation', :deliver => true)
invitation.deliver(:unexpected)
invitation.should have_received(:deliver).with(:expected, :arguments)
end
end
"""
When I run `rspec failed_message_expectations_spec.rb`
Then the output should contain "expected: (:expected, :arguments)"
And the output should contain "got: (:unexpected)"
Scenario: generate a spy message
Given a file named "spy_message_spec.rb" with:
"""ruby
describe "have_received" do
subject(:invitation) { double('invitation', :deliver => true) }
before { invitation.deliver }
it { should have_received(:deliver) }
end
"""
When I run `rspec --format documentation spy_message_spec.rb`
Then the output should contain "should have received deliver"
