JUnit best practices in Java
No doubt writing good JUnit test cases is a rare skill just like writing good Code. A good, well thought and well written JUnit test can prevent several production issues during initial development or later maintenance in Java application. Though one can only be perfect in writing JUnit test by practice and a level of business knowledge which is important to envision different scenarios on which a method gets called, some best practices or experience of other developer may help to guide other programmers. In this Java article I am sharing some JUnit tips and Junit best practices which I have learned and follow while writing unit tests using JUnit for Java programs. One of the book which helped me a lot is Pragmatic Unit Testing in Java with JUnit by Andrew Hunt and Dave Thomas, This book shares lot of JUnit best practices which is worth reading and learning if you are serious about Unit testing using JUnit. Never undermine importance of automated testing and test cases written by Developer who writes the code and that's the reason many company are asking programmer to design, code and provide unit tests during there Java interviews. These JUnit best practices not just apply to JUnit but to any other testing framework as well like TestNG, they are more on testing and writing test cases which is more important skill than tool like JUnit or TestNG.
