This document discusses software testing, including an overview of the test process and types of testing. It describes the test process as having stages from unit testing to acceptance testing. A test plan is created before testing and includes what will be tested, the test environment, and approvals. The main types of testing covered are black box testing which tests functionality without knowledge of internal structure, white box testing which tests internal structure, alpha and beta testing which test before and after release, and defect testing which aims to find defects before delivery.

- 2. OVERVIEW Introduction Test process Test plan Types of testing
- 3. INTRODUCTIONTO SOFTWARE TESTING process of executing a program or system with the intent of finding error more than just error detection operating the software under controlled conditions to: o Verification o Error detection o Validation
- 4. TESTPROCESS creation of test strategy, creation of test plan/design and execution of tests Stages of test process are: o Unit testing o Module testing o Sub-system testing o System testing o Acceptance testing Unit Testing Module Testing Sub-system Testing System Testing Acceptance Testing Fig. : Stages in Test process
- 5. TESTPLAN document which is created before the testing process Includes: types of testing to be performed, high level scope of the project, environmental requirement of testing process not just management documents also need of software engineers involved in designing and carrying out system tests Test plan template • Test plan identifier • Introduction • References • Test items • Features to be tested • Features not to be tested • Approach • Item pass/Fail criteria • Test environment • Risks • Approvals
- 6. TYPES OF TESTING Black box testing White box testing Alpha testing Beta testing Clean room testing Defect testing
- 7. I. BLACKBOXTESTING o Testing either functional or non-functional without reference to the internal structure of the component or system Fig. : Black box testing o Also known as Functional testing Input Output Executable Program Types of Testing (Continued)
- 8. II. WHITEBOXTESTING o Also known as Structural testing o Testing with reference to the internal structure of the component or system o Applicable to lower levels of testing: Unit Testing ,Integration Testing o Performance of application can be tested Fig. : White box testing Test Data Component code for testing Test Output Types of Testing (Continued)
- 9. iii. Alpha Testing: o Is employed for Off the self software before software goes to beta testing iv. Beta testing: • Is released to a limited audience outside for further program fault or bugs v. Clean room testing: o related to incremental development model,In which incremented software delevered to customer with less important features which are added on each increment.And customers feedback is taken in account vi. Defect Testing : o Main goal is to identify defects before the system is delevered to the customer Types of Testing (Continued)
- 10. CONCLUSION. . . Software testing- an important phase in SDLC which makes a software product less faulty, and satisfying product which meets the requirements of user…
