September 29, 2020 — Unit testing has become an integral part of the software development process. It is the level of testing at which the components of the software are tested. In this article, Fortune Ikechi will show you the core principles of testing, explore various libraries for testing an application, and see how to test units (or components) of a React Native application. By working with a React Native application, we’ll solidify our knowledge of testing. Read more…

September 7, 2020 — Postman allows you to manually test your APIs in both its desktop and web-based applications. However, it also has the ability for you to automate these tests by writing JavaScript assertions on your API endpoints. In this article, Kelvin Omereshone will learn how to write automated tests on web APIs with Postman. In order to follow along to this tutorial, you’ll need at least a fair amount of familiarity with Postman. Read more…

July 3, 2020 — Testing gives confidence in written code. In the context of this article, ‘testing’ means ‘automated testing’. Without automated testing, it is significantly harder to ensure the quality of a web application of significant complexity. Fails caused by automated testing may lead to more bugs in production. In this article, Chidi Orji is going to show you how React developers can quickly start testing their app with the React Testing Library (RTL). Read more…

June 24, 2020 — Building a well-functioning application requires good testing; otherwise, knowing whether your application works as expected would be a matter of guesswork and luck. Jest is one of the best tools available for testing React applications. In this article, Adeneye David Abiodun will show you everything you need to create a solid test for your React components and application. Read more…

June 17, 2020 — UI or User Interface test is a form of acceptance testing done to verify the user flows of your front-end application. The emphasis of these kinds of software tests is on the end-user that is the actual person who will be interacting with your web application on a variety of devices ranging from desktops, laptops to mobile devices. In this final part of Mirage JS Deep Dive series, Kelvin Omereshone will be putting everything you’ve learned in the past series into learning how to perform UI tests with Mirage JS. Read more…

June 1, 2020 — In this article, Chidi Orji will explore the concept of error boundaries in a React application. You’ll work through an example app to see how we can use error boundaries to deliver a better app experience. Finally, you’ll integrate Sentry into our error boundary for realtime error reporting. The only prerequisite is that you have some familiarity with React class components. Let’s dig in! Read more…

March 17, 2020 — There isn’t a ton of mystery when it comes to what makes for an attractive and modern-looking design these days. What’s not always clear, however, is the usability aspect of it. In other words, have the pathways you’ve designed for users intuitive enough? The truth is, it’s all really just a guessing game unless you start getting user feedback early on. Thankfully, Indigo.Design has a usability testing solution to help us out. Read more…

February 18, 2020 — Whether you’re building a new site or you’re managing a live one, you can’t afford to make any changes without a process for cross-browser testing and a tool to do the heavy lifting for you. LambdaTest’s wide array of tests are the answer. From fully automated cross-browser tests to semi-automated tasks, we’re going to explore a much more efficient way to review your websites and all their browser iterations for errors. Read more…

Requests may be vague (“the form is broken”), too subjective (“the page doesn’t load fast enough”), or difficult to assess without seeing it yourself (“the page still isn’t updated”). You could schedule some time to walk through the issues or bugs with your client, but a better solution to this often disruptive and frustrating process is to create a fool-proof system that’s easy for clients to leave feedback and even easier for you to implement and resolve it. In this article, Suzanne Scacca brings you great suggestions. Read more…
