#2. TestNG

Being an open-source testing framework for the Java programming language, it was created to simplify and automate the testing process. It has a wide range of features, including annotations, support for data-driven testing, assertions, parallel test execution, and more.

TestNG also allows for flexible configuration, which makes it an ideal choice for automating unit tests.

Features of TestNG:

• Annotations: Being a seamless Java testing library, it provides many annotations that are used to control the test execution flow. These include @BeforeClass, @AfterClass, @BeforeMethod, @AfterMethod, and @Test.

• Data-driven Testing: TestNG allows you to specify parameters for a test and have them run multiple times with different values. This makes it easy to create data-driven tests.

• Assertions: TestNG provides several assertion methods that can be used to validate the expected results.

• Parallel Test Execution: This library supports running tests in parallel, allowing multiple tests to run simultaneously. This helps to reduce the overall test execution time.

• Flexible Configuration: TestNG allows you to configure how tests are executed, including how they are run, what order they are run in, and more.

• Reports: It allows you to generate reports after each test run which can be used to analyze results.

• Integration with IDEs: Being a top Java testing library, you can easily integrate it into most major IDEs, such as Eclipse, IntelliJ IDEA, and NetBeans. This makes it easy to write and execute tests from within the IDE.

If you want to test your application thoroughly to deliver your customers a glitch-free experience, hire Java developers with QA expertise in manual & automation testing.

#3. Mockito

Mockito is an open-source Java testing library designed to help you create mocks and test your code in an efficient and effective way. It can be used with any Java testing framework and provides support for both unit and integration tests.

Moreover, this testing library offers a powerful suite of features that allow you to easily create, stub, and verify mock objects and results, as well as provide easy-to-use APIs to set up the testing environment.

• Easy-to-use API: Mockito’s API is straightforward and easy to use, allowing you to quickly and easily create mocks, stubs, and verify results without having to learn a complex library.

• Flexible mocking: It allows you to create mocks for any type of object, including interfaces and classes, making it extremely versatile.

• Mocking framework: Moreover, this tool comes with its own mocking framework, which helps you to easily create mocks for any type of object and set up the testing environment.

• Verification: Being a security-oriented library, it allows you to verify the behavior of your mocked objects and ensure that they are performing correctly.

• Integration testing: This library also provides integration testing capabilities that allow you to easily test how your code interacts with other components in the system.

• Automated mocking: At last, you can use it to automatically generate mocks from existing code, making it easier to set up the testing environment.

Overall, being one of the top Java libraries for testing allows businesses to deliver incredible application UI. So, connect with a Java development company with expertise in testing solutions.

#4. AssertJ

AssertJ is an open-source Java library that allows developers to write concise and easy-to-read assertions. It provides powerful assertions, expressive and flexible verification, and fluency for writing tests.
