Component Testing (or Module Testing) Explained with a Simple Example

A component is the lowest unit of any application. So Component testing; as the name suggest, is a technique of testing the lowest or the smallest unit of any application.

Component testing sometimes is also referred as Program or Module Testing.

An application can be thought of a combination and integration of many small individual modules. Before we test the entire system as a whole, it is imperial that each and every component OR the smallest unit of the application is tested thoroughly.

How to Perform Software Product Testing – Detailed Process and Methods with Examples

Often times, teams treat them as any other software (i.e. internal applications built for a specific client or team; not accessible by the general public; non-revenue generating) and that is the starting point of trouble.


Software Product Testing needs a custom test style and strategy to add value. Software Product development and sustenance is in itself a complex ecosystem and to thrive testers need to adapt. Continue reading →

For any software application, both Unit testing and Integration testing are very important as they each employ unique processes to test the software application. But one or both of them cannot replace Functional testing.

In this article, we will understand Unit, Integration, and Functional testing and clarify the differences between these forms/levels of testing.

Mutation Testing: Testing Technique with a Simple Example

Sci-Fi fans: Don’t get your hopes up. This isn’t that kind of mutation we are talking about :)

What is Mutation Testing?

Mutation testing is a fault-based testing technique where variations of a software program are subjected to the test dataset. This is done to determine the effectiveness of the test set in isolating the deviations.

It sounds a little complicated, isn’t it?  Continue reading →

Today’s topic is the difference between Retesting and Regression Test.
