How to Write Great Unit Tests With JUnit: Major Features.

JUnit is a unit testing framework for the Java programming language. JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks. Its main use is to write repeatable tests for your application code units.

Parameterized tests are a good way to define and run multiple test cases, where the only difference between them is the data. Here, we look at three different frameworks commonly used with JUnit tests. When writing unit tests, it is common to initialize method input parameters and expected results in the test method itself.

Therefore, you are writing junit test cases where your are forced to wait using method Thread.sleep(1000) or some other mechanism until the thread has finished its job before you can test your code’s results. This is not a very good idea and could be unreliable but this way at least you could check whether your code is working or not.

In this guide, we will learn how to do JUnit 5 exception testing with an example. Let’s assume that we have a class StringUtils that has a method convertToInt to convert a given string into Integer. If the given string is Null or empty, then the method will throw an IllegalArgumentException with a message: “String must be not null or empty“.

Testing Java Interfaces With JUnit. By Matt Albrecht, February 01, 2003.. JUnit's design encourages good testing habits by moving much of the menial bookkeeping to the automated system. However, JUnit does not provide an easy way to write tests for testing subclasses. Some developers cut-and-paste their tests between test classes, which.

In the past, I have shared some great books for learning unit testing in Java like the Test-Driven and JUnit in Action, and today, I am going to share some of the online courses you can use to learn JUnit 5 or Jupiter, the latest version of JUnit library, and Mockito to write a unit test for your Java application.
