Acceptance Testing
In acceptance testing, testers test a system for acceptability. They evaluate the compliance of a system with business requirements. After that, they test whether the product is acceptable for delivery. For instance, if you’re building a Lego house, you’ll check whether each piece is perfect. That comes under unit testing, which we already discussed in the previous section. The next step is to ensure whether all the instructions have been followed. For that, you need to check after the completion of each stage of the Lego building. Acceptance tests scan the running application. They ensure the proper functioning of user flows, user inputs, and designated actions.
Visual Regression Testing
Whenever some new change is pushed in an application, there’s a slight chance that a preexisting feature may break. That’s where regression testing comes in handy. Visual regression testing is another form of regression testing that’s related to UI. It involves capturing UI screenshots and comparing them with previous screenshots. The previous screenshots are captured from the live site or the baseline. Visual regression testing is unique to the front end. Testers use image comparison tools to detect differences between the two shots. If you’re building something new, save this testing process for last.
Accessibility Testing
As I noted earlier, accessibility testing is to ensure that everyone can access an application. This includes users over a certain age and those with hearing and visual disabilities. Accessibility testing mostly involves checking whether your app is compatible with devices like a screen reader.
What’s visible on the screen is the only thing that matters to end users. A firm needs to check how a site looks and functions before it goes live. To ensure an impeccable graphical user interface (GUI), front end testing is a must.
In this post, we’re going to understand what front end testing is, its types, importance, and other details. We’ll also cover how it differs from back end testing as well as challenges that are unique to front end testing. In short, I’ll provide a complete conceptual overview of front end testing.
What Is Front End Testing?
The front end is the client-side section of a program. We can say that it involves everything visible while using an application. Every web application has a three-tier architecture. It includes clients, servers, and information systems or resources. The presentation layer comprises the client. Front end testers test this layer. They perform GUI testing and test usability and how a site or application works.
For example, suppose you’re testing a shopping application. Front end testers check whether the look and feel of the website are aligned with the client’s requirements. Also, they check if the required features like adding an item to the shopping cart or menu click events are working properly. Front end testing covers a wide array of testing strategies. We shall discuss this in the next sections. But before diving in, we’ll take a look at how front end testing is different from back end testing.
