watch this if you don't get TDD
A practical example of applying test driven development (TDD) in Java to implement the ArrayList, an iconic data structure. TDD involves writing unit tests for your application before writing the production implementation.
Java's ArrayList is a "resizable array" implementation of the List interface. Today I live code a simple implementation of the ArrayList in Java with TDD to demonstrate how the ArrayList uses fixed length arrays to support resizable list semantics, and how to use test driven development to write better source code and unit tests.
Using JUnit 5, AssertJ, and commons-lang3.
