Questions & Answers

Q: How does Cypress differ from Angular's built-in testing library, Protractor?

Cypress offers a better developer experience with a more expressive DSL for writing tests and a test runner that provides time travel debugging capabilities, features that Protractor lacks. Cypress is also better suited for modern Angular projects compared to Protractor which was originally developed for AngularJS.

Q: What can I test with Cypress?

Cypress allows you to test various user interactions like clicking buttons, filling out forms, and navigating through your app. You can also make assertions about the content and behavior of your app by using Cypress's powerful API.

Q: Can Cypress be used with TypeScript?

While you can set up your specs to run on TypeScript, there isn't much benefit in doing so as you can pull in types in a plain JavaScript file. Cypress provides excellent tooling and autocomplete even without using TypeScript.

Q: How can Cypress be extended with custom methods?

You can extend Cypress with custom methods by creating helper methods in the support folder's commands subdirectory. These methods can be reused across different test suites, making your tests more concise and readable.
