Hi

Black box testing is not thing but where the knowledge of internal code is not required. Functional and regression testing are black box testing.Black box testing can be done by manual or using automation tool. In Manual we do functional and regression testing by entering the data manually. where as in automation we record the script.

Testing is a process of verifying where a product meets the customers requirement. The product is build by the developers and the testers used to find bugs in the products to improve the quality of the product. To find these bugs they first determine what are the tests to be done on the product.These tests are written as test cases.After the test case is prepared the testers used to run these test cases on the developed application manually. This is called manual testing.

Instead of running these testcases manually if they use some automation tool to execute the test cases then it is called automation testing.

In both the above case the tester acts as a end user . They get the exe of the application and executes the test cases on it .This type of testing the application without the knowledge of the coding part is called as Black box testing.

Testing anapplication by seeing the internal codings is called white box testing.

its overall funcationality testing !

simple example :-

login window for this u need to perform backbox testing ! all u need to do is enter user name and password press enter then cancle ...

testing the the application with the help of tool is called automation testing

testing an application with out help of any tool is called manual testing

Black box testing means testing based on functionality aand requirments of customer..

Hi

White -box testing might include access to the source code behind the application and the tester can debugg and actually spot the in some unit of code or point to a particular batch of code which is not right and mostly white box involves mostly system testing whereas incase of blackbox testing the tester doesnt have access to the source code and blackbox testing mostly includes User acceptance testing Functinality testing Interface Testins volume testing and others.

Hello! Black box testing is a part of the manual testing. manual testing means without using any third party(tool) you only don that tests.Black box testing means the combinations of Usability testing Functional testing Performance testing and security testing tese combinations are called Black box testing.

Dear Jyothi

Black box testing nothing but the functionality of the application would be tested against to the customer provided requirement documents while providing the input. For this the tester no need to check the internal structure coding/statements.
