Learn what Selenium is, its architecture, advantages and more for automated cross browser testing. Working with iFrames and Cypress.io is possible, and let’s demonstrate Cypress test automation with some functional code.Īlso, get started with this complete Selenium automation testing tutorial. So let’s stop giving more context and start doing something worthwhile. You’ll be loading up the website, serving accurate content, and then writing scripts to ensure you see what you expect. Also, we validate the E2E flows to determine if the entire application is working at the point where the end-user interacts with it.įor a website, it means testing the website as it appears in a real browser. Therefore, we test iFrames during the functional testing phase. ![]() Why is it essential to test the iFrames on our web pages? The logical answer is to guarantee everything is working as desired. Therefore, if we use iFrames to display external content on our website, we must ensure they work correctly. However, it remains vital in today’s web world (Especially with React and Flutter webs). IFrame usage was much more popular before the explosion of JavaScript on the web (Resuscitated with HTML5). ![]() It is why Google Maps, YouTube, and others encourage users to embed their content using an iFrame element rather than hosting any portion of the complex web app ourselves, our page views the web service through an integrated window. When we add an iFrame to a page, we look through a window from that page into another site, with full interactivity within that space. In this tutorial on how to handle iFrames in Cypress, you will learn how to write reliable tests for web applications that use iFrames and run them on the cloud Cypress grid.Īn iFrame in plain English is considered a window onto another document or site the element’s purpose is to place content from one HTML document in the context of another (Basically embedded things). Testing iFrames with automated testing tools is necessary for many web apps. In addition, it could create flake test scripts if we don’t operate them correctly.Ĭypress is an excellent framework for testing the front-end and back-end, but interacting with iFrames could be tricky. Each iFrame is treated as a separate document via the browser, adding extra steps in our automation testing code as we need to map our elements inside those iFrames imagine the complexity of handling nested iFrames. Still, it decreases the app’s testability from the UI perspective. Using iFrames is a good idea from the modern web development perspective. The element has a somewhat convoluted history introduced by Microsoft around 1997 and supported in early versions of Internet Explorer, it was incorporated into HTML 4.0, banished from XHTML, and reintroduced in HTML5. One of the oldest yet simple integration strategies is using iFrames when examining these integrations. However, we can find most of these web apps work with each other where the integrations happen either from the Front-end or Back-end. Pre-requisite: Make sure to log in to the proper npm user through npm login.In today’s web development world, finding standalone web apps is challenging. You may also take advantage of using npm link to test out changes in the local built out dist folder in the sample consumer folders before publishing to npm. There are example specs that use the cy.iframe() command for you to test at the top level cypress folder and in the separate JavaScript ( samplecypressconsumerjs) and TypeScript ( samplecypressconsumerts) consumers. We recommend installing and starting up Cypress through the cypress:open command to test your changes. You may check out this repo's samplecypressconsumerts folder to see an example of a TypeScript Cypress project installing and using the cy.iframe() custom command. You may check out this repo's samplecypressconsumerjs folder to see an example of a JavaScript Cypress project installing and using the cy.iframe() custom command. within ( ( ) => ) Examples JavaScript Example cy.iframe(iframeSelector: string): Chainable cy.
