Effective Java is a book that offers useful insights and best practices for Java developers. One of the topics covered in the book is testing, and how to make it more effective. One of the patterns suggested for better testing is the Template Method Pattern. This article will explore how this pattern can improve the testability of Java applications.

Applying this pattern in testing can help to reduce the amount of duplicate code and increase the maintainability of tests. Consider a scenario where you need to test a complex algorithm with multiple steps. Instead of writing the same setup code for each test case, you can use the Template Method Pattern to define the common steps in a superclass and let the test cases implement the specifi...
