When it comes to building a great website or mobile app, testing is just as important as coding. But with digital immunity, testing takes on a whole new importance.

Developers test their code in chunks as it is written. Error monitoring during the development cycle alerts engineers when conflicts arise and helps them identify the root cause. So, you may wonder then, in the age of DevOps and continuous delivery, is end-to-end testing still needed? Not only is it viable, but it is also essential to [validate requirements, configurations, and functionality](https://saucelabs.com/blog/the-case-for-end-to-end-testing-in-the-age-of-devops).

In my 18 years of working in quality engineering and the testing community, I’ve developed some best practices to help organizations create and manage their overall test strategies. This is the first in a 10-week series on what testers wish their CIOs and CTOs knew about testing. Each week, I’ll share my experience to help educate tech leaders on key priorities their testing teams need them to understand. This week, we’ll talk about the user experience.
