Feature: Returning a value
Use `and_return` to specify a return value. Pass `and_return` multiple values to specify
different return values for consecutive calls. The final value will continue to be returned if
the message is received additional times.
Scenario: Nil is returned by default
Given a file named "returns_nil_spec.rb" with:
"""ruby
RSpec.describe "The default response" do
it "returns nil when no response has been configured" do
dbl = double
allow(dbl).to receive(:foo)
expect(dbl.foo).to be_nil
end
end
"""
When I run `rspec returns_nil_spec.rb`
Then the examples should all pass
