As products and services deploy faster and faster, quality assurance (QA) has to adapt and deliver more coverage in less time while maintaining high quality. In this article, Toptal Software Engineer Jade Russel Hancox examines how we can use the user flow to boost the speed and efficiency of QA processes without compromising on quality.

A relatively recent addition to React, hooks have already changed React development for the better through improved code readability and state management. But how do we test them? In this article, Toptal React Developer Avi Aryan outlines why it is crucial to test hooks and introduces us to his React Hooks testing routine.

Tests should keep apps from being flaky. But tests themselves can become flaky—even the most straightforward ones. Here's how we dove into a problematic test on a PostgreSQL-backed Rails app, and what we uncovered.

In an age of continuous delivery, Java developers have to be confident that their changes don't break existing code, hence automated testing. There's more than one valid approach to it, but how can you keep them straight?

Test automation engineers continuously research the latest tools and techniques to ensure that their test automation framework stays fast, stable, and easy to use. In this article, Toptal Freelance Java Developer Simon Stratton will take a look at some tips that you can use to update your framework for 2019 by improving your use of Selenium Grid, Java’s wait function, and Chrome DevTools.

Dealing with a real database for integration and end-to-end testing can pose some challenges. One way of working around them is to use an in-memory database that integrates well with the testing framework and provides APIs to manipulate its state from test code. In this article, Toptal Freelance Software Engineer Mikhail Angelov shows how you can write integration and end-to-end tests easily for your Node.js and MongoDB application without having to write complicated setup/teardown code.

Do you think testing your iOS or Android apps manually is faster than writing automated tests for them? Calabash, the cross-platform acceptance framework, busts that myth once and for all. In this article, Toptal Freelance Software Engineer Alexander Gedevanishvili shows how Calabash, with its support for Cucumber, makes writing automated UI tests as simple as writing instructions in plain English.

In this tutorial, you will learn how automated testing works for the iOS platform and how to implement it in your project.

Your software isn’t fully tested until you write integration tests for it. While unit tests help ensure that functions are properly written, integration tests help ensure that the system is working properly as a whole. In this article, Toptal Software Engineer Luka Blažecki uses Node.js to explain why integration testing is important for every development platform and how to write clean, composable integration tests.
