Summary

In the blog post by Gleb Bahmutov, the author addresses the challenge of flaky tests in Cypress, particularly focusing on the issue arising when an HTML form submission leads to a new page load during ongoing test interactions, causing elements to detach from the DOM. The post discusses the original error reported by a user, where the test failed due to a "Element is detached from DOM" error, and explores various strategies to resolve such flakiness. These strategies include using `cy.pause` to step through tests, implementing explicit waits for page loads through `cy.wait`, checking for URL changes with `cy.location`, monitoring network requests with `cy.route2`, and inspecting the window object to detect when a new page is fully loaded. The solutions emphasize synchronizing test actions with application state changes, ensuring tests are robust and reliable by waiting for the application to reach the expected state before proceeding with further interactions.
