Gray box testing

Gray-box testing :It is a combination of white-box testing and black-box testing. The aim of this testing is to search for the defects if any due to improper structure or improper usage of applications.

If one performs testing on both the functional & structural part of the application then that method of testing is known as grey box testing.

This is done by the Test Engineer who have knowledge of the structural part.

It is not encouraged in IT Companies.

LEVELS OF TESTING

www.thesmartpath.in

Unit Testing

Unit testing is a software development process in which the smallest testable parts of an application, called units.

It is White Box Testing.

It is done by Developers.

INTEGRATION TESTING

It is Second level of Testing.

It is White Box Testing.

It is done by Developers.

Interfaces or linking programs are developed & modules are integrated. Once the modules are ready the developers will integrate the modules using interfaces & will test whether the interfaces are working properly or not that testing is known as Integration Testing.

SYSTEM TESTING

It is Third level of Testing.

It is Black Box Testing.

It is done by Testers.

Once the application is deployed into the environment then the environment & the application both are known as system and the testing performed on that system is called as System Testing.

USER ACCEPTANCE TESTING

It is Final level of Testing.It is Black Box Testing.It is done by Testers.If at all one performs same system testing in the presence of the user then it is UAT. It is final level of testing. It is a type of testing performed by the Client to certify the system with respect to the requirements that was agreed upon. This testing happens in the final phase of testing before

moving the software application to Market or Production environment.
