What does Blackbox and Whitebox testing means?

[Trance Maniac]

I am intermediate programmer in this up growing programming world. I just loves to do programming and testing everyday. I am learning the programming languages: C++, C Sharp, Core Java, SQL and HTML. I want know what does Blackbox and Whitebox testing means and why do we use it?? Please help me.

The whitebox and blackbox testing resides in the software testing or testing category and it is one of the important part of the Software Development Life Cycle. The software testing method's are mainly grouped in blackbox and whitebox testing. For a complete software examination, both testing's tests are required. And this both mechanism is used to explain the point of view that a test engineer must take when designing test cases.

WhiteBox Testing: The product's known under the working process, and you can do the test to check that if meets or not each of the internal operation's along with the design specifications for all internal components which has been inspected. And they are also known as glass box, structural, clear box and open box testing
BlackBox Testing: The function of any product's which design specifications can be meet for every test to prove that it meet the requirements of the function or not. And they are also known as functional testing.

My knowledge say that the Blackbox and Whitebox are testing methods. Blackbox testing methods treats the system as a 'black-box', so it does not explicitly use anything of the internal structure. Usually the blackbox testing known for focusing on testing functional requirements. Synonyms for blackbox include: behavioral, functional, opaque-box, and closed-box. And Whitebox testing provides us to peek inside the "box", and mainly focuses on using internal knowledge of the software to guide the selection of test data. Synonyms for white-box include: structural, glass-box and clear-box.

BlackBox Testing: It is not based on any information of the internal design or coding. Also known as functional testing. This tests are mainly base on requirements and functionality of the application.
WhiteBox Testing: It is totally based on information of the internal logic of an application's coding. Also known as glass box, structural, clear box and open box testing. This tests are mainly base on coverage of code statements, conditions and branches.
This both are testing method of the Software testing. There are also other method of software testing which is known as Grey Box Testing.

Whitebox testing is done only when the tester comes with the permission to the internal data structure's and algorithm's also considering the code that implement this. Blackbox testing does testing by not using any piece of information of internal implementation. The whitebox and blackbox testing is are part of the software testing method and in this one more testing method is added that is Grey box testing. This all three methods are considered to be very important. Hope your problem will be solved.
