However, this topic can be pretty confusing for beginners, especially due to the complicated lexicon. “Shadow DOM vs. virtual DOM,” for instance, is quite a common confusion among developers, especially junior ones.

Today’s web applications are more complicated than ever. Libraries like React have opened up a whole new world of application complexity and functionality. As an experienced developer, you know that it’s important to test every part of your web application. You probably already have a plan for testing your server’s code. That’s great! But it’s…
As developers, you are probably familiar with this scenario: you went over a code review with another developer (which you do, right?), pushed the latest fixes, ran a couple of tests by yourself, and with a big smile upon your face, you sent a message to the QA guy, Joe (a generic name for a…
Software developers need faster feedback to fix bugs when they are less expensive to correct. One strategy for providing earlier feedback is to shift testing earlier in the process (shift-left). Teams can detect and fix bugs with the least impact by running unit, integration, and E2E UI tests as early as possible. There’s a second…
Continuing our trend of covering testing-related topics, today, we talk about test coverage techniques. What are these techniques, and why should you be aware of them?

When it comes to software quality, many people refer to it as a quasi-mythical, unmeasurable property. On the one hand, I see the truth in acknowledging the nuance and subjectivity in defining a complicated factor such as quality. On the other hand, there must be some objective way to assess the quality of code. Otherwise,…
Notwithstanding testing in production—which should be part of any mature QA strategy—you should avoid using production data directly. Instead, use test data. This article explains how to safely generate test data, how to manage that test data, and last, how to use the test data. Here’s a summary of what we’ll cover What Is Test…
When it comes to an application, there are two kinds of user activity: the kind you can control and the kind you can’t. Irrespective of these actions, you need to build your application to work for all valid cases. The users’ choice of browsers is something that’s out of your control. You have to make…
Protractor is a test framework for web applications. Even though its primary use is for performing end-to-end testing in Angular and AngularJS applications, you can also use it for regular, non-Angular websites. Protractor testing interacts with your application just like a real user would because it runs tests using an actual web browser. Today’s post…
