Software Testing Services: Types and Levels

Software testing is the process of checking any computer software with the intention of finding any errors and correcting it. It undertakes to check it for its quality and reliability so that the end users are satisfied and do not face any problem once they start using it. Particular functions, specifications and performance of the developed software are examined and evaluated. 

The two processes combined to check software are Validation and Verification. Verification undertakes to see if the software is conforming to its specification or not whereas Validation is the process of checking what the user really requires.

Software testing services is generally categorized into two types of testing. They are:

1. White-box Testing

In white-box testing knowledge of the internal design and code of the software is required. It is basically used for the verification process.

2. Black-box Testing

Knowledge of the internal design or code is not required in this type of testing. It is used for the validation process so tests are based on requirements and functionality of the software only.

There are different testing levels of software as well. They are as follows:

• Unit testing

• Integration testing

• System testing


This test is conducted by the developers where each module is tested individually.


This type of testing is performed once all the modules are unit tested. It undertakes to identify errors in the software. It is further sub-divided into other types namely Big Bang Integration testing, Top Down Integration testing, Bottom Up Integration testing and Mixed Integration testing.


System testing is performed to check that the overall system’s function and elements are performing well or not. The different types of system tests are: Alpha Testing, Beta Testing, Acceptance Testing and Performance Testing.
