Cypress Migration: Upgrading from a Lower Version to the Latest Version

Having Cypress to the latest version, one is sure to get new features, security updates, and bug fixes. However, migrating from a lower version to the latest one requires careful planning and testing to avoid breaking your test suites.

1. New Functionality: Many times, new releases do come with some new functionality, such as better support for testing frameworks, enhanced commands, and sometimes new integrations.

2. Bug Fixing: Upgrade helps fix problems or restrictions that the previous version may have encountered, thereby stabilizing your test better.

3. Performance Enhancement: With every upgrade of Cypress, there are generally minor performance enhancements where tests run faster and more resource-efficiently.

4. Security: Your test environment remains secure with the latest patches.

1. Check Cypress's Release Notes: Look at the release notes for every version since yours to search for breaking changes, deprecations, and new features. In fact, Cypress has very good release notes that contain important migration steps or breaking changes.

2. Upgrade Cypress:

Using the following command will upgrade you to the latest version:

Alternate command if you are using yarn

3. Tackle Breaking Changes: As if you'd approach this by breaking down the changes that you'll affect in your test suite. Frequently breaking changes might entail how commands work and how timeouts and assertions have changed.

Example: The older version of Cypress sometimes uses different API structures, and older commands, such as cy.route(), have been superseded by new versions with cy.intercept().

4. Test the Upgraded Suite: Run your test suite against the upgraded code and ensure all should now be in good working condition. Concentrate on important tests and then on the full suite. Test with richer testing by using CI tools in your pipeline for the upgrade.

5. Fix Issues and Warnings: Generally, Cypress throws a lot of warnings due to outdated methods or configurations. So, be aware of warnings and work on your code as needed.

6. Update Plugins and Dependencies: Certainly, some third-party plugins, or even some third-party dependencies might not be compatible with the latest version of Cypress. So, do update those too for the best possible outcomes while keeping test failures at bay.

The best practice is to always back up your current test suite with Git, or with any other version control, before changing it.

1. Migrate incrementally: If you are significantly several versions behind, then migrating a single main version at a time would be quite more manageable to do.
2. Use Cypress Dashboard : You may be monitoring the performance of your tests before and after migration just to ensure that there were no regressions introduced.
3. Track changes: Keep track of everything that you change during your process, such as maybe command updates or config changes, so that you don't forget them

 

Moving to the newest release of Cypress can be sure that the test suite is well up to date with modern web development practices. Careful review of release notes, rigorous testing, and processing of breaking changes makes migration smooth and ensures running optimally with newest improvements brought by Cypress.
