Black box testing

Blackbox testing is a method of software testing that focuses on the functionality of an application or system without considering its internal workings or implementation details. In blackbox testing, the tester is only concerned with what the system does and not how it does it. This means that the tester does not have any knowledge of the internal code or architecture of the system, and they only interact with it through the user interface or other external inputs and outputs. This approach allows the tester to evaluate the system from the perspective of an end user, which can help identify any potential issues or bugs that may not be apparent when looking at the system from the inside.
