Both Eclipse and JUnit are two of the essential tools for Java Developers. Eclipse is a Java IDE, Integrated Development environment which allows you to code, run, and debug Java programs from a single window. At the same time, JUnit is a unit testing library that will automatically test your Java code. You can write JUnit tests, and then you can run them automatically using Maven or Gradle plugin at build time. You can further automate your build using Jenkins, which means your Unit test will run continuously and automatically, reporting any break at the earlier possible opportunity.

2 Ways to test Exception in JUnit : Annotation vs try-catch
Error handling is a core part of coding but most of the time it just went under the radar when it comes to unit testing. How do we write a JUnit test that verifies that an exception is thrown? With the try-catch construct, of course, except that this time, the code throwing an exception is a good thing—the expected behavior.
