Feature: Mixed responses
Use `and_invoke` to invoke a callable when a message is received. Pass `and_invoke` multiple
callables to have different behavior for consecutive calls. The final callable will continue to be
called if the message is received additional times.
Note: The invoked callable will be invoked with the calls arguments, so it is recommended to
use a `lambda` or similar with the same arity as your method but you can use a `proc` if you
do not care about arity (e.g. when raising).
Scenario: Mixed responses
Given a file named "raises_and_then_returns.rb" with:
"""ruby
RSpec.describe "when the method is called multiple times" do
it "raises and then later returns a value" do
dbl = double
allow(dbl).to receive(:foo).and_invoke(lambda { raise "failure" }, lambda { true })
expect { dbl.foo }.to raise_error("failure")
expect(dbl.foo).to eq(true)
end
end
"""
When I run `rspec raises_and_then_returns.rb`
Then the examples should all pass
