Differentiating Integration Testing and unit testing

Software testing plays a vital role in the affirmation of the software quality and reliability. It is a never ending process which starts with the very initial stage of software development and continues with Software Development Life Cycle. Testing may be in any form depending on the type of software under consideration. This paper furnishes the basics of Software Testing and steps involved in the testing procedure. We will review two significant approaches for testing software which are Unit testing and Integration Testing. We will study the brief overview of the both the approaches and also compare them on the basis of various parameters like modules, problem discovery and techniques involved.
