Concept of Black box testing

[Jabeen]

Hi All,

In one of the programming book I had read the word "Black box testing". But It is too complicated for me to understand this concept as there is lots of pages over this.

Can you able to suggest me what is exact concept of Black box testing?
If possible then please explain it with example, so that it will be more easier to understand.

Hi,

*. The "Black box testing" is also referred as functional testing.

*. In the "Black box testing" tester is unaware about internal works of the item.

e.g In a black box testing on a software the tester only aware about the what the inputs and what the desired outputs should be.

* The tester of Black box testing doesn't know anything about programming code of the software design.

This is all about black box testing according to me and I hope it will helpful for you.

Please go through the some below important points regarding "Black box testing":

1. "Black Box Testing" is a type of the testing strategy in which there is no need of any knowledge regarding internal code and design.

2. Black box testing design takes the system as a 'black box', so that Black box testing does not explicitly use internal structure information.

3. Black box testing normally targeting over tsting of the functional requirements.

4.The Black box testing also referred as "opaque-box" or "functional" or "behavioral" or "closed box" tesing.

Hi friend,

Below are the some advantages of the black box testing which I know:

Advantages of Black box testing:

1.In the black box testing ,the tester doesn't required any knowledge of particular programming language.

2.In this type of testing test cases can be designed immediately after the completion of the specifications.

3.In this type of testing the test is done according to the point of view of the user of the system, not according to the designer.
