 This Ruby gem synchronizes [Capybara](https://github.com/teamcapybara/capybara) commands with client-side JavaScript and AJAX requests. This greatly improves the stability of an end-to-end ("E2E") test suite, even if that suite has timing issues.

 Why are tests flaky?

-A naively written E2E test will have [race conditions](https://makandracards.com/makandra/47336-fixing-flaky-integration-tests) between the test script and the controlled browser. How often these timing issues will fail your test depends on luck and your machine's performance. You may not see these issues for years until a colleague runs your suite on their new laptop.

 Using the middleware is optional, as the [JavaScript snippet](#including-the-javascript-snippet-required) already for AJAX requests on the client. However, using the middleware covers some additional edge cases. For example, the middleware detects requests that were aborted on the frontend, but are still being processed by the backend.
