Black-Box Testing
Black box testing is defined as a testing method in which functionality of the application under test (AUT) is tested. Testing of the Application is done without looking the structure of internal code,details of implementation and knowledge of the internal paths of the software. This type of testing(Black -Box) is entirely based on software requirements and specifications. INPUT --------> BLACK BOX --------> OUTPUT In Black Box testing , basically we focus on input and output without worrying about internal knowledge of the software program. Steps to do Black-Box Testing:- 1) Initially, specifications and requirement of the system are inspected. 2) Tester chooses valid inputs(positive test scenario) to check whether system under testing is correctly processes them as well as invalid points(negative test scenario) to check system under testing is able to detect them. 3) Expected outputs is determined by tester for all those inputs. 4) Test
