CHAPTER -14
(SOFTWARE TESTING)
Software Testing :- It is a important methods to use check whether the actual software product fulfil the expected requirement and to ensure that software product is defect free, It involves execution of software components automated using manual or automated tools to evaluate whether it is bug free or not, the primary purpose of software testing is to identify errors gaps, or missing requirements in comparison to actual requirements.
The testing team executes the software with an intention of finding error in it and a successfully test is one that finds.
Need and importance of Software Testing:-
· Finds bugs or error in the developed software
· Resolve bugs before delivery of software
· Solve your many for the long term as if bugs are caught in the earlier stages of software testing the it cost less to fix.
· Security and satisfaction after developed.
Types of Software Testing:-
There are three types.
1.) White Box Testing
2.) Black Box Testing
3.) Grey Box Testing
1.) White Box Testing:- It is a software testing techniques in which internal structure, design and coding of software are tested. It is done to verify the flow of input-output in the software and to improve design usability and security. In this testing programming skill are required to design test cases. In white box testing, code is visible to the testers so it is also called clear box testing, open box testing transpiring box testing and glass box testing. If focus on checking of predefined inputs against expected desired outputs.
In white box testing various tests are performed like that :-
· Path testing,
· Loop testing,
· Condition testing
· Memory consumption testing
· Performance Testing
2.) Black box Testing:- It is a software testing techniques in which the functionality of software are tested without having any knowledge of internal codes structure, implemented details and internal paths, It is entirely based on software requirements and specification and manly on focuses on input and output of software.
For Example :- we use an operating system a website or our own customs application and just focusing on the inputs and outputs without knowing the internal code/ implementations, It is also known as behavioral testing or specification based testing.
3.) Grey Box Testing :- It is combination of black box and white box testing, In this techniques the tester test the software with partial knowledge of the testing is manly used in web based applications as if any errors is caught by the tester then it is resolved in real time. It helps to test both presentation layer as well as internal coding structure of a software.
