Race condition with capybara-webkit and DatabaseCleaner

[miks]

We have js functionality that calls load json on page load.
It's making problem when DatabaseCleaner is cleaning database in rspec "after" hook while capybara-webkit is still somehow active and doing request to controller.

We have hook like this, but it not working correctly all the times as sometimes json loading happpen even after this hook.

config.after(:each) do
    if Capybara.current_driver != :rack_test
      safety = 10
      while (page.evaluate_script('jQuery.active').to_i > 0) && (safety > 0)
        safety -= 1
        sleep 0.5
      end
    end
end

Question: is there some way to tell capybara-webkit to stop all request or even close tab/window after test is finished?

Active requests are generally terminated when calling reset on capybara. Is it possible that you're trying to clean the database before reset is called? Can you paste some of your capybara or database_cleaner setup?

It's possible that something else is running asynchronously. The two that jump out at me from your spec_helper are Sidekiq and and ParallelTests. I haven't tried either of those recently and I'm not sure if there would be any issues.

I am experiencing the same problem. Placing a sleep 1 before my DatabaseCleaner.clean resolves the issue, but is obviously not the solution.

@jferris: problem already existed before Sidekiq was added to project. @tf do you happen to have ParalleTest in your project?

[tf]

@miks No. Simply, rspec (2.14.1), capybara (2.1.0), capybara-webkit (1.0.0).

Actually it's very simply to recreate this error. Just add continuous ajax content loading (for example: call function itself to load data one more time on successful ajax request).
So, I guess it's more related to rspec after hook.

Ok, it's due to fact that capybara "after" hook (defined within gem) is called after all other after hooks described within project (spec_helper.rb).

Just add "Capybara.reset_sessions!" before database cleanup:

Capybara.reset_sessions!
DatabaseCleaner.clean
