What is black box Software testing?

Blackbox testing, known as Behavioral testing is a software testing method which is used to test the software by focusing on the input and output. It does not require any knowledge of internal code, internal path, and implementation details of the software application.

You can test any software application which you want to. From the operating system to the database, the black box can be used to detect the system. The only thing you need for this is the input and the output. It doesn’t demand any internal code.
