Building Single Page Applications is easier said than done. While the chief purpose of an SPA is improved user experience, it is almost never the result. As you get on with testing your single page application, you may find some challenging errors. This is predictable because the pages in an SPA are dynamic and virtual, which makes it hard for developers to lay enough focus on the UX. Let’s discuss some of the most common errors which appear during single page application testing. But, before that, let me explain what makes a single page application.
What Is a Single Page Application?
The defining characteristic of an SPA is that it handles all routing using its client-side JavaScript instead of redirecting the browser to a new page. As a result, browsers natively offer some free frontend functionality, and an SPA overrides that. It is often confused that single page applications are those which involve client-side template creation, MVC framework, AJAX calls, etc. However, all of this stuff can also be used just as well with other kinds of applications. The key factor from a tester’s perspective is that browser features intersect in an SPA, which predictably leads to some serious problems without careful testing.
