The Best Java Libraries for Testing in 2023

Most of us strive to be more efficient, motivated and, most importantly, productive in testing. And we do everything necessary to do so. The best way to show it is to automate repetitive regression tests, so as to eliminate the human factor in monotonous labor. In turn, we like to know all the current trends in the world of automation. This is the only way we can be at the top of our profession. And in today’s article we will talk about what libraries will be popular in 2023 for the most commonly used programming language Java.

We need Java libraries to speed up the development process, to make writing this code more concise and understandable. Java libraries do not affect and do not impose any restrictions on the architecture of the software product. Moreover, they can be used as a set of subroutines close to their functionality. There are quite a few libraries available today. In this article we will consider which of them will be the most popular in 2023.

Selenium

One of the most popular libraries, Selenium, has been in the lead for years. The amount of web content is constantly growing, and the easiest way to automate testing is to start with a time-tested library. That’s why Selenium continues to be the very library that newcomers to automated testing can start with. What’s more, many companies use Selenium extensively to build their test automation frameworks and products.

Today’s Selenium ecosystem consists of three main parts:

  • The first and most important is Selenium WebDriver, which helps create automated test suites and test suites to scale across different testing environments.
  • The second part is the Selenium IDE, which allows uncomplicated automated scripts to go through various scenarios in the initial stages.
  • The last is Selenium Grid, a server that allows you to manage tests in different environments from one central repository, simplifying startup and maintenance.

Selenide

Selenide is an intelligent add-on to Selenium WebDriver that takes full advantage of it and allows you to minimize the amount of code by reusing repetitive code in individual classes. Additional advantages include Ajax support for stabilizing autotests and powerful selectors which allow you to accurately find the right element even in a very complex project with a branched and dynamically changing DOM (Document Object Model) architecture. In addition, Selenide has a relatively simple configuration, making it easy and fast for beginners and professionals to write automated tests.

Selenoid

Selenoid is a server that allows you to run dozens of tests simultaneously in docker-container browsers. Selenoid has very high performance that outperforms Selenium Grid. Ease of installation and deployment is another advantage of Selenoid. It also scales and updates quickly. By running in docker containers, each browser runs clean and isolated from the main system and consumes no more than 20 megabytes of RAM (RAM) when idle.

TestNG

TestNG is a testing environment based on JUnit (Java) and NUnit (C#); it has long been popular with Java testers. It will also be in wide demand in 2023 because of its use for unit, functional, integration, and end-to-end testing. One of the main drivers for the continued use of this framework is that many projects have already been written using it. Multiple annotations and the ability to use autotest parameterization make it more flexible and easily adaptable to any tester’s needs.

Cucumber

The next framework that will also be popular in 2023 is Cucumber. Its popularity is due to the fact that tests are written in a common language understood by autotestors and people far from development and testing, such as analysts and project managers. Cucumber uses a BDD (Behavior-Driven Development) approach; it allows third-party people to create their own scripts, which increases the quality and reach of autotests.

JUnit

JUnit is designed for unit testing and will be very popular in 2023 because of the growing number of projects on microservice architecture. The TDD (Test-Driven Development) technique allows it to take the lead by reducing the risk of errors at the earliest stage, when there is no code yet. With the release of the new version of JUnit 5, which introduces parameters and asserts, creating autotests takes a whole new level, allowing you to perform tests where it wasn’t possible before.

Lombok

The Lombok library reduces the amount of code you write, improving its readability. It’s easy to add it to your project and you only need to do it once. Lombok also generates code at compile time, making autotests faster and more stable.

Most of the libraries and frameworks listed in this article will help you stay at the forefront of automated testing and make your daily life easier. They will also define the point of near-term development in the coming year 2023.
