Rails 6.1 升级后，作业规范用 Minitest::UnexpectedError 包装错误

Question

升级到Rails 6.1后，测试失败：

class MyJob < ActiveJob::Base
  class MyError < StandardError; end

  def perform
    raise MyError
  end
end

describe MyJob, type: :job do
  it "throws an error" do
    expect do
      perform_enqueued_jobs { MyJob.perform_later }
    end.to raise_error(described_class::MyError)
  end
end

此规范因错误而失败

expected MyJob::MyError, got #<Minitest::UnexpectedError: Unexpected exception> with backtrace:

仔细观察抛出的错误，它看起来像这样：

    69:
    70: describe MyJob, type: :job do
    71:   it "throws an error" do
    72:     expect do
    73:       binding.pry
 => 74:       perform_enqueued_jobs { MyJob.perform_later }
    75:     end.to raise_error(described_class::MyError)
    76:   end
    77: end

[1] pry(#<RSpec::ExampleGroups::MyJob>)> perform_enqueued_jobs { MyJob.perform_later }
Minitest::UnexpectedError: MyJob::MyError: MyJob::MyError
    /usr/src/app/spec/lib/my_job_spec.rb:5:in `perform'
    /usr/local/bundle/gems/activejob-6.1.6/lib/active_job/execution.rb:48:in `block in perform_now'
    /usr/local/bundle/gems/activesupport-6.1.6/lib/active_support/callbacks.rb:117:in `block in run_callbacks'

    /usr/local/bundle/gems/activesupport-6.1.6/lib/active_support/callbacks.rb:126:in `block in run_callbacks'

似乎错误以某种方式被包裹起来Minitest::UnexpectedError，但原始的底层错误仍然存​​在。

知道如何解决这个问题吗？

这些更改是在 Rails 6.1 中进行的perform_enqueued_jobs

因此，要修复您的测试，您需要重写它，如下所示：

describe MyJob do
  it "throws an error" do
    expect do
      described_class.perform_later
      perform_enqueued_jobs
    end.to raise_error(described_class::MyError)
  end
end
