This document outlines different types of software testing including the objectives, principles, types, and levels of testing. The types of testing discussed are white box testing, which validates code implementation against design, and black box testing, which is done without knowledge of internal programming details. The levels of testing covered include unit testing, integration testing using different approaches, system testing of security, recovery, and reliability, and acceptance testing stages of alpha and beta. The overall goal of testing is to find issues and verify requirements to improve system quality before delivery.

- 3. WHAT IS TESTING? Testing is the process to find whether the system is fulfill all the requirement written in the SRS.
- 4. OBJECTIVE • System quality. • Verification and validation. • Find the fault before it deliver to the client. • Test whether system fulfill customer requirements.
- 5. PRINCIPLES • Exhaustive testing is impossible • Early testing • Testing is context dependent • Absence of error fallacy • Testing shows presence of error • Defect clustering • Pesticide paradox
- 6. TYPES OF TESTING • White box testing- It is performed based on the knowledge of how system is implemented. The objective of WBT is to validate whether code implementation follow intended design. • Black box testing- It is one which is done without knowing internal details of programming. When BBT is applied to an application the tester only knows input and expected output.
