Job spec wraps error with Minitest::UnexpectedError after Rails 6.1 upgrade

Question

After upgrading to Rails 6.1, a test is broken:

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

This spec fails with the error

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

When looking closer what error is thrown, it looks like this:

    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 }

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

It seems like the error is somehow wrapped with Minitest::UnexpectedError, but the original underlying error is still there.

Any idea how to fix this?

Answer 1

These changes were made in Rails 6.1 with perform_enqueued_jobs

So to fix your test you need to rewrite it like shown below:

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
