Feature: expect a message on any instance of a class
Use `expect_any_instance_of(Class).to receive` to set an expectation that one
(and only one) instance of a class receives a message before the example is
completed. The spec will fail if no instance receives a message.
Scenario: expect a message on any instance of a class
Given a file named "example_spec.rb" with:
"""ruby
describe "expect_any_instance_of" do
before do
expect_any_instance_of(Object).to receive(:foo).and_return(:return_value)
end
it "verifies that one instance of the class receives the message" do
o = Object.new
expect(o.foo).to eq(:return_value)
end
it "fails unless an instance receives that message" do
o = Object.new
end
end
"""
When I run `rspec example_spec.rb`
Then the output should contain "2 examples, 1 failure"
And the output should contain "1) expect_any_instance_of fails unless an instance receives that message"
