In this method, the tester selects a function and gives input value to examine its functionality, and checks whether the function is giving the expected output or not.
#WHITE BOX AND BLACK BOX TESTING SOFTWARE#
In this testing, the test engineer analyzes the software against requirements, identifies the defects or bugs, and sends it back to the development team.
All test cases are designed by considering the input and output of a particular function. It does not require programming knowledge of the software. It is a software testing technique that examines the functionality of the software without knowing its internal structure or coding. The primary source of black-box testing is a specification of requirements that are stated by the customer. To read more about white box testing, you can refer to the following link – White box testing. It is well suitable and recommended for algorithm testing. It is also known as structural testing, clear box testing, code-based testing, and transparent testing. The primary goal of white-box testing is to focus on the flow of inputs and outputs through the software and strengthening the security of the software.
#WHITE BOX AND BLACK BOX TESTING CODE#
It requires programming knowledge, as it majorly focuses on code structure, paths, conditions, and branches of a program or software. It is done at lower levels, as it includes unit testing and integration testing. The main objective of white-box testing is to test the application's infrastructure. It is performed by Developers, and then the software will be sent to the testing team, where they perform black-box testing. The clear box or white box, or transparent box name denotes the ability to see through the software's outer shell into its inner workings. The term 'white box' is used because of the internal perspective of the system.
Whereas, in White box testing, there is a testing of internal coding and infrastructure of software.īefore jumping directly to the comparison, let's first see a brief description of white-box and black-box testing. In Black box testing (or "behavioral testing"), the tester understands what the program is supposed to do, rather than its internal working. In this article, we will discuss white box testing and black box testing, along with the comparison between them. Next → ← prev Difference between White Box testing and Black Box testing
