In a detailed blog post by Gleb Bahmutov, various strategies are outlined for working with iframes in Cypress testing, addressing the inherent challenges due to the security restrictions and limitations of DOM traversal commands. The post provides a comprehensive guide on interacting with DOM elements within iframes, including techniques to spy on and stub network requests, such as window.fetch and XMLHttpRequest, with practical examples using a static HTML page. It also discusses methods to manage cross-domain iframe access by altering browser security settings, and the use of custom commands to simplify repetitive tasks. Additionally, the post introduces a Cypress-iframe plugin developed by a community member, which offers simplified commands for handling iframes, showcasing how robust testing scenarios can be implemented by following these guidelines and utilizing available resources.
