Top 10 Testing Tools for Java Developers to Choose in 2023
Testing is an inevitable part of any software development. Choosing the right framework for testing remains a question. You never want to use any low-quality testing tools to run an app experience. As per reports, the global mobile application market will grow and reach USD 567.19 billion by 2030.
And to match up these standards the applications should have the best quality to compete. So, here we present the best testing tools for Java developers to use. Want to know them? Let’s explore.
Best testing tools for Java developers
Here are some in-depth testing tools used by developers and testers.
Unit testing
Here are some unit testing tools to choose for your applications.
JUnit 5
If you talk about open-source & well-known testing frameworks, JUnit 5 is your answer. As the name suggests, it serves as the best unit testing tool. JUnit 5 is a huge collection of modules coming from different sub-projects. These projects are JUnit Platform and JUnit Jupiter.
In this, JUnit is the foundation to launch test frameworks on the JVM. Whereas, JUnit Juniper contains the data model to test the engine to run Jupiter-based tests.
Spock
Moving to other testing tools for Java developers to use for applications. JUnit Runner and its methods for describing the application views serve as an inspiration. These characteristics aid in dividing the code into blocks and phrases. So, that non-technical users can understand it with ease
TestNG
Just like JUnit 5, TestNG offers you a complete testing framework with multiple solutions, Apart from unit testing, the framework also covers different types of testing levels. That means it reduces the headache of switching between frameworks.
So, this framework supports component, integration, and end-to-end testing levels. TestNG with this became the perfect solution for different testing needs. Plus, this testing framework increases the future scope of the application.
Assertions
There are multiple testing frameworks to assess different results. So, in JUnit, there are many dependencies to extend the acceptance testing. And AssertJ library is one of them. You can hire Java developers for your assistance. So, this library is quite handy, especially for repetitive methods. Also, it has many useful methods to speed up the testing process to reduce the code.
Mocks
As name suggests unit testing focuses on a single unit. However, there are many units in the code that don’t have meaning and means of execution. So, mocking is one of the testing tools for Java developers that come to support you. These are quite handy and allow for expected results from creating mock objects. These are:
Mockito
Mockito library helps in the complete mock cycle of testing. Right from creation, verification, and testing. This mocking framework involves small logic portions as per the unit tests. So, in most cases full mock uses the object or just use the Spy.
EasyMock
Another testing tool in strong competition of Mockito. It is one of the most notable testing frameworks. It doesn’t have partial mocking semantics testing support. So, Mockito supports the partial testing of your project. It all depends on your project about the partial testing.
PowerMock
Test writing can be static, final, and private. Picking the right testing tools for Java developers is crucial. So, it’s not just the Mockito you will need PowerMock. Plus, the best point is testing frameworks work well with the PowerMock. With JUnit 5 PowerMock offers a great incompatibility. So, rethink to test design or include unit code potions for easy maintenance.
Component testing
Components are the group of units. And these need to be tested timely for compatibility checks. So, component testing involves each object testing to check its compatibility with software. You can pick black box testing types for this. And if you want to check this in Java, Cucumber is the best tool.
This is an automated test framework that offers extensive support to BDD (Behavior Driven Development). These scenarios are in Gherkin syntax as per the logic and functionalities. The framework is well known for its to-the-point nature.
Plus, the Gherkin feature files offer test cases with Java code files. You can hire Java developers for your assistance. And if you run a parallel test the syntax is easier to read and understand. Even the team specifies features & behaviors for tests.
Web testing
When checking for web testing, you have a lot of testing tools for Java developers to choose from. You can choose any one as per preference. Besides the long list, you have two well-known Java web tools:
Selenium WebDriver
It is a robust and browser-based testing tool. It offers automated tests for the websites whether local or remote. You may call it the perfect testing tool. Due to its language, syntax, and browser-controlling code lines. Being a reputed automation testing tool offers a single interface to write scripts in Java. Selenium is highly compatible with Java, Python, C#, etc.
Serenity
Another testing tool is Selenium, which is a Java library to integrate with Selenium WebDriver. And it enhances the JUnit capabilities. It helps to write various automated tests to verify the functionality of web services. This framework is just for documentation, regression, and acceptance tests.
Performance testing
Last, but not least. Performance is also crucial for application quality. And these testing tools for Java developers test stress, endurance, load, etc. So, the performance offers an in-depth check of the complete application for its working.
And Gatling is one such well-known testing tool for Java. It is an open-source testing tool that offers enterprise applications in Java. Especially it offers support for the HTTP protocol. The load testing tool offers to record the actions as per the Java code. Also, it runs your code on aggregators, load injectors, etc.
Key takeaways for testing tools for Java developers
The test-driven development ensures the complete process of development. So, for innovative results and faster loading the testing tools ease your process. And if you use testing tools you can get the best market-focused solutions. Test-driven development involves high-quality checking and assurance for later deployment.
Here is an overview of the testing tools you choose from:
- Unit testing ensures a complete set of automation tools. Such as JUnit 5, AssertJ, Mockito, Cucumber, etc.
- And for components tests, you have WebDriver, and Gatling and there are plenty for the web tests.
Conclusion: Java is a reputed and high-level language. Plus, it has a plethora of testing tools for developers to ease the testing process. Above mentioned are some of the well-known tools to use. For more consideration. consult Java web application development services for your projects.
FAQs
