What’s new in Cypress 10? How it will change your current testing requirements

By Priyanka Bhat & Ganesh Hegde, Community Contributors -

Cypress 10 was released on 1st, June 2022 with breaking changes. It’s been some time since Cypress has shipped such a huge change. There are a lot of changes in Cypress 10, and it will break your existing Cypress tests. 

Though initially, you might choose not to upgrade for Cypress 10 for a short period, eventually, you would need to update with Cypress 10 to align and use the latest features of Cypress. So, you would need to know what are the new changes in Cypress and how it is going to impact your existing tests. Also, you need to migrate the existing project to Cypress 10.

This article explains the new changes in Cypress 10 and how you can migrate your existing project to Cypress 10.

New features in Cypress 10

There are several new features in Cypress 10, which are intended to make Cypress Test Automation easier for the QAs.  Here are the new features and changes in the latest version of Cypress 10.

1. New Improved User Interface (UI)

Cypress now has a new and improved User Interface that helps you to choose and execute the tests across browsers easily. It now has two different UIs for Component and E2E Testing respectively, which are discussed in detail in the subsequent sections.

2. Component Testing in Cypress 10 (Beta)

Cypress Component Testing allows you to build and test any component quickly. With the components testing offered by Cypress 10, it allows developers to test their application code/components in a real browser. Developers can debug them using Chrome DevTools and fix them instantly. This feature makes Cypress the first choice for both developers and testers and avoids having a different tool for E2E and component testing.

Cypress provides a User Interface for executing Component Tests, making tests more interactive and providing a rich experience. The developer can render modern framework components such as React, Angular, and Vue components and test them in isolation.

Cypress also provides you with a setup wizard, you can easily set up your project for Component Testing.

3. E2E Testing in Cypress

E2E Testing in Cypress 10 is mostly written by QA/Test Engineers to cover the integrated component tests. Now, end to end testing in Cypress is separated from Component testing. 

Before Cypress 10, the Integration folder was used to put all the end-to-end tests, but with Cypress 10 there is no Integration Folder anymore as it is termed as the e2e folder.

4. File and Folder Structure Changes

File and Folder Structure Changes Cypress 10

Here are a few noteworthy changes in the file and folder structure with Cypress 10:

  • The integration folder is renamed the E2E folder. That means cypress/integration is now cypress/e2e
  • Spec file extensions have  changed from testfile.spec.js/ts to testfile.cy.js/ts
  • cypress/support/index.js and are renamed to cypress/support/e2e.js
  • The pluginsFile option is removed. This option is now part of new setupNodeEvents() and devServer() configuration options in your config file
  • The testFiles option is removed. This option is replaced with the new specPattern option.
  • The ignoreTestFiles option is removed. This option is now replaced with the excludeSpecPattern option
  • The baseUrl and experimentalSessionAndOrigin options are no longer available as top-level configuration options and now, it can only be defined within the e2e configuration
  • cypress.json file is no longer supported, you need to replace it with one of these file names cypress.config.js, cypress.config.ts, cypress.config.cjs or cypress.config.mjs

Cypress Configuration File will now have the following three parts:

  • Global configuration:  Option applicable for both e2e and component
  • E2E section: Options that are applicable only for e2e tests
  • Component section: Options that are applicable for only component tests

5. Additional flag support for opening Cypress window

Since Cypress has two different parts, component and e2e, if you open the Cypress window with the command npx cypress open, you need to choose manually to land on the specific type of testing. 

Cypress is providing two different flags now, each different for component and e2e as seen below: 

  • To open the Cypress E2E Testing window directly
    npx cypress open --e2e 
  • To open the Cypress component testing window directly.
    npx cypress open --component

6. No more Cypress examples downloaded when you download Cypress as a fresh project.

Earlier, when you installed the Cypress by default, there were many example testcases; with Cypress 10 those examples are removed. Now you need to create/download from the Cypress E2E Project setup window.

7. Option to Change the Browser in Test Runner window has been introduced

Earlier, the browser selection option was only at the Cypress Project level window, not the browser selection can be done on the Project window or Test runner window.

To Sum it up

Cypress 10 is bundled with long-awaited features, one might think Cypress 10 is just a visual User Interface change but that’s not completely true. Cypress has made the changes to internal APIs as well, these changes are required for them to support upcoming long-awaited features such as IFrame Support, Webkit support, etc. 

Cypress wanted to make this migration hassle-free, so it has introduced a migration assistant or migration helper as well which automatically converts your old project into Cypress 10 standards. It has laid a strong foundation for releasing interesting features in the upcoming days.

While Functional Testing is one of the important parts of the Testing application, when performing functional testing you should keep in mind that functionality should work across the browser and platform combinations. This is why Cross Browser testing with Cypress is a must to ensure a seamless user experience.

Note: BrowserStack supports Cypress 10, try running your Cypress 10 Tests on Real Devices

Moreover, it is recommended that you test on real devices and browsers to ensure that the tests are more accurate when performed under real user conditions. BrowserStack’s real device cloud provides access to 3000+ real devices and browsers to perform end-to-end testing, cross browser testing, and functional testing. It easily integrates with frameworks like Cypress, Selenium, Playwright, etc., and all the major CICD tools like Jenkins, Gitlab, Azure, CircleCI, etc.
