Cypress is such a great testing tool because it works inside your application and browser and because their best practices help right stable automated tests. One of these best practices is only to test one domain at a time. This principle follows the same-origin policy. …

And why you should care. I am becoming a big fan of component testing. With component testing, you test in earlier stages of the development process, and instead of testing an entire application (or a big chunk), you test smaller parts of the application. …

And I have always found it difficult to explain how much they are actually saving. I use arguments such as: “Adopting testing in the early stages of development…

Testing Down the Pyramid — I love my work as a freelance test automation specialist. Companies hire me to help to implement effective test automation strategies.
