Rubyonrails 在 Rails 6.1 升级后，作业(job)规范使用 Minitest：：UnexpectedError 包装错误

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:

当仔细观察抛出的错误时，如下所示:

    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 }

似乎错误以某种方式被Minitest::UnexpectedError包装，但原始的底层错误仍然存在.

你知道怎么解决这个问题吗？
