Testing for Programmers – Beginners

 

My new article Testing for Beginners available on CodeProject.

This article provides basic information about software testing for programmers in a beginner’s level.

Explain in detail about subject – testing is out of scope of this article. Just a simple Google search can give you more than enough results. So I wrote this article with just programmers in mind.
