Software Testing Presentation Transcript:
1. What is Testing??“Testing is the process of executing a program with the intent of finding errors”. It is a process of evaluating a system by manual or automatic means and verifying that it satisfies specified requirements or identify differences between expected and actual results.
2. Why Software Testing
It is important as it cause impact on operational performance and reliability if not done properly. Effective software testing helps to deliver quality software products that satisfy user’s requirements, Needs and expectations. If done Poorly, it leads to high maintenance cost and user dissatisfaction

If done Poorly, it leads to high maintenance cost and user dissatisfaction
4. Verification & Validation (V&V)
Verification – Are we developing a product right? Validation – Are we developing the right product ? It is the difference between 'What and How' Two types of V &V is there Static V & V Dynamic V & V
5. Principles of Software Testing
Testing is the process of executing a program with an intent of finding error and it should be planned long before testing begins. Test cases must be written for invalid and unexpected, as well as for valid and expected input conditions. A good test case is one that has high probability of detecting an error.
6. Principles of Software Testing….
All the test cases should be traceable to the customer requirements Testing should be planned long before testing begins Testing should begin 'in small' and process towards testing 'in large' To be most effective, testing should be conducted by independent third parties.
7. Purpose and Benefit Testing
The main objective of testing is to help clearly describe system behavior and to find defects in Requirements, design, documentation, and code as early as possible. The test process should be such that it should reduce the number of defects of the software product to be delivered to the customer. All tests should be traceable to customer requirements.
8. Programmers don’t like to test WHY?
Testing is considered Low Tech Low excitement Suitable for people with lots of time on their hands Many programmers believe that once they have gone through the formality of running a few perfunctory tests against it, their code works When building an electronic circuit, a hardware designer goes over it carefully in several times before ever applying power For programmers, if a program happens not to crash and even generates output that looks like it might be correct, the programmer is tempted to believe that the program works
9. Objective of Software Tester
The goal of a Tester is to find defects. The goals of a Tester is to find Defects and find them as early as possible. The goal of a Tester is to find defects and find them as early as possible and make sure they get fixed.
