1 SOFTWARE TESTING Presented By Abhilash.S

 What is Software Testing?  Fundamentals of software Testing Error/Mistake? Defect/Bug/Fault? Failure? 2

Project? Product?  Software Testing=Verification + Validation  Verification?  Validation? 3

4 Testing Objectives  Testing is a process of executing a program with the intention of finding an error.  Whether the application is developed according to customer requirements or not.  To make sure all the defects are resolved and finally to deliver a risk free product to the customer.

 Incorrect Requirements  Wrong Design  Poor Coding  Work Pressure. 5

6 Testing Principles  Exhaustive testing?  Risk based testing?  Defect clustering?  Pestiside paradox?

 What is SDLC?  Types of SDLC Models?  What is Waterfall model?  What is V-Model 9CM

8 Software Testing techniques Software Testing techniques  Static Testing Reviews. Walkthroughs.  Dynamic Testing White box Testing. Black box Testing.

9CM  White box testing Unit Testing. Integration Testing.  Black box testing System Testing. User Acceptance Testing.

10 Reasons for conducting WBT  As source code is visible to developers to finding the errors and rectifying the errors is so easy.  Programmers will conduct WBT to reduce the many defects as soon as possible.

9CM White box Testing Will be carried out in 4 ways Big bang Approach. Top-Down Approach. Bottom-Up Approach. Sand witch Approach.

9CM White box Testing Design Techniques Test case. Exhaustive Testing. Code coverage.  Statement coverage.  Condition Coverage.  Path coverage.

13 Black Box Testing  What is BBT?  Reasons for conducting BBT Black Box testing Techniques  Equivalence class partitioning(ECP)  Boundary value analysis(BVA)
