Feature: Raising an error
Use `and_raise` to make the test double raise an error when it receives the message. Any of the following forms are supported:
* `and_raise(ExceptionClass)`
* `and_raise("message")`
* `and_raise(ExceptionClass, "message")`
* `and_raise(instance_of_an_exception_class)`
Scenario: Raising an error
Given a file named "raises_an_error_spec.rb" with:
"""ruby
RSpec.describe "Making it raise an error" do
it "raises the provided exception" do
dbl = double
allow(dbl).to receive(:foo).and_raise("boom")
dbl.foo
end
end
"""
When I run `rspec raises_an_error_spec.rb`
Then it should fail with:
"""
1) Making it raise an error raises the provided exception
Failure/Error: dbl.foo
RuntimeError:
boom
"""
