确保使用RSpec时Rollbar已报告错误

Question

我正在尝试编写一个测试，以确保rollbar确实报告错误。

it 'does not mute rollbar' do
        expect(Rollbar).not_to receive(:silenced)
        expect(Rollbar).to receive(:error).with(any_args).and_call_original
        expect { query }.to raise_error(unknown_exception)
end

不幸的是，在报告未挽救的错误时，rollbar不能在:error、:critical、:warning等方法中使用。

我在rollbar sourcecode中看到了report_exception_to_rollbar和call_with_rollbar，它们都是用Rollbar.scoped包装的。

因此，我尝试使用以下命令进行测试：

expect(Rollbar).to receive(:scoped).with(any_args).and_call_original

但它也告诉我：

 Failure/Error: expect(Rollbar).to receive(:scoped).with(any_args).and_call_original
       (Rollbar).scoped(*(any args))
           expected: 1 time with any arguments
           received: 0 times with any arguments

如何确保异常被rollbar捕获并使用rspec进行测试？

Answer 1

您希望确保运行的行是Rollbar.log call in exception_reporter.rb。(Rollbar.error、Rollbar.warning等只是Rollbar.log的包装器。)

试试这个：

expect(Rollbar).to receive(:log).with(any_args).and_call_original

Answer 2

log不适合我，但error适合。下面是一个在Rails应用中使用ApplicationJob的示例。

describe "ApplicationJob" do
  describe "rollbar" do
    context "when rollbar is included" do
      before do
        class EasyJob < ApplicationJob
          def perform(*)
          end
        end

        allow_any_instance_of(EasyJob).to receive(:perform).and_raise(StandardError) # rubocop:disable RSpec/AnyInstance
      end

      it "makes a call to rollbar" do
        expect(Rollbar).to receive(:error).with(any_args)
        expect { EasyJob.perform_now }.to raise_error(StandardError)
      end
    end

    context "when rollbar is NOT included" do
      before do
        class HardJob < ActiveJob::Base
          def perform(*)
          end
        end

        allow_any_instance_of(HardJob).to receive(:perform).and_raise(StandardError) # rubocop:disable RSpec/AnyInstance
      end

      it "does NOT make a call to rollbar" do
        expect(Rollbar).not_to receive(:error)
        expect { HardJob.perform_now }.to raise_error(StandardError)
      end
    end
  end
end
