I have a method that has a begin / rescue block in it. How do I test the rescue block using RSpec2?
class Capturer
def capture
begin
status = ExternalService.call
return true if status == "200"
return false
rescue Exception => e
Logger.log_exception(e)
return false
end
end
end
describe "#capture" do
context "an exception is thrown" do
it "should log the exception and return false" do
c = Capturer.new
success = c.capture
## Assert that Logger receives log_exception
## Assert that success == false
end
end
end
Use should_receive
and should be_false
:
context "an exception is thrown" do
before do
ExternalService.stub(:call) { raise Exception }
end
it "should log the exception and return false" do
c = Capturer.new
Logger.should_receive(:log_exception)
c.capture.should be_false
end
end
Also note that you should not be rescuing from Exception
, but something more specific. Exception
covers everything, which is almost definitely not what you want. At the most you should be rescuing from StandardError
, which is the default.
