Difference between blackbox and whitebox tests

What is Black Box testing?

In black-box testing, a tester doesn’t have any information about the internal working of the software system. Black box testing is a high level of testing that focuses on the behavior of the software. It involves testing from an external or end-user perspective. Black box testing can be applied to virtually every level of software testing: unit, integration, system, and acceptance.

What is White Box testing?

White-box testing is a testing technique which checks the internal functioning of the system. In this method, testing is based on coverage of code statements, branches, paths or conditions. White-Box testing is considered as low-level testing. It is also called glass box, transparent box, clear box or code base testing. The white-box Testing method assumes that the path of the logic in a unit or program is known.

Black Box Testing Vs. White Box Testing

• In Black Box, testing is done without the knowledge of the internal structure of the program or application whereas in White Box, testing is done with the knowledge of the internal structure of the program.
• When we compare Blackbox and Whitebox testing, Black Box test doesn’t require programming knowledge whereas the White Box test requires programming knowledge.
• Black Box testing has the main goal to test the behavior of the software whereas White Box testing has the main goal to test the internal operation of the system.
• Comparing White box testing and Black box testing, Black Box testing is focused on external or end-user perspectives whereas White Box testing is focused on code structure, conditions, paths, and branches.
• Black Box test provides low granularity reports whereas the White Box test provides high granularity reports.
• Comparing Black box testing vs White box testing, Black Box testing is a not time-consuming process whereas White Box testing is a time-consuming process.
