Writing Micro-Benchmarks With Japex

Do you need a micro-software to help you implement micro-benchmarks in micro-time? If your answer is yes, you need Japex. This Java tool was designed specifically to offer simple solutions for writing wall-clock benchmarks for chunks of code. The spirit of Japex borrows from its famous "sibling", JUnit, so if you are familiar with JUnit then you will recognize the application logic here. In this article, you'll learn:

Download And Install Japex

Download Japex from its web site. Make sure you download the latest Japex distribution. Install by extracting the .ZIP archive to the preferred place on your machine.

Japex's benchmarks are based on the JARs libraries from the /Japex/lib folder and they're most often executed through Ant scripts. Throughout this article, you'll place the benchmarks in the /Japex main folder under a sub-folder, named tests (you should create the test folder manually).
