The document discusses software testing techniques, outlining its objectives such as demonstration, detection, prevention, and improving quality. It details three main testing methods: white box, black box, and gray box testing, highlighting their approaches and effectiveness. Additionally, it emphasizes the importance of testing in identifying defects and ensuring software quality during development.
![OBJECTIVE OF TESTING Cont…
• Demonstration:
• It demonstrates functions under special conditions and shows that products are
ready for integration or use.
• Detection:
• It discovers defects, errors and deficiencies. It determines system capabilities and
limitations, quality of components, work products and the system.
• Prevention:
• It provides information to prevent or reduce the number of errors clarify system
specifications and performance. Identify ways to avoid risk and problems in the
future.
• Improving quality:
• By doing effective testing, we can minimize errors and hence improve the quality of
software. [1]](https://image.slidesharecdn.com/presentationontopic-191015155534/85/Software-Testing-Technique-in-Software-Engineering-4-320.jpg)
![WHITE BOX TESTING
• White-box testing also known as clear box
testing, glass box testing, transparent box
testing, and structural testing.[2][3]
• It is highly efficient in detecting and resolving
problems, because bugs can often be found
before they cause trouble.
• We can thus define this method as testing
software with the knowledge of its internal
structure and coding.
• The tester has complete knowledge of how the
program components interact.](https://image.slidesharecdn.com/presentationontopic-191015155534/85/Software-Testing-Technique-in-Software-Engineering-8-320.jpg)
![BLACK BOX TESTING
• Black box testing is also called as functional
testing.[5] A black box is any device whose
internal details and workings are not understood
or accessible to its user.
• It is testing of software without any knowledge of
the coding or internal structure in the program.
• The main aim is to test how well the system
conforms to the specified requirements for the
system.
• It makes sure that all inputs are properly accepted
and outputs are correctly produced](https://image.slidesharecdn.com/presentationontopic-191015155534/85/Software-Testing-Technique-in-Software-Engineering-9-320.jpg)
![GRAY BOX TESTING
• It is defined as testing software and also
having some knowledge of its internal
logic and underlying code.
• It is a technique to test the application with
limited knowledge of the internal working
of an application.[4]
• Good to use in penetrating testing.](https://image.slidesharecdn.com/presentationontopic-191015155534/85/Software-Testing-Technique-in-Software-Engineering-10-320.jpg)
![BY WHOM TESTING IS DONE
• Testing is being done by all those who are intricate to
the software development. [6]
• The various professionals are indulged in testing the
software:
• Project Manager, Software Tester, Software Developer
and End Users.](https://image.slidesharecdn.com/presentationontopic-191015155534/85/Software-Testing-Technique-in-Software-Engineering-11-320.jpg)

Software Testing Technique in Software Engineering
- 2. SOFTWARE TESTING • Software testing is the process used to measure the quality of developed computer software. • It exhibits all mistakes, errors and flaws in the developed software. • The testing of software is an important means of assessing the software to determine its quality.
- 3. OBJECTIVE OF TESTING • The objective of testing is to find problems and fix them to improve quality. • There are four main objectives of software testing: Demonstration Detection Prevention Improving quality
- 4. OBJECTIVE OF TESTING Cont… • Demonstration: • It demonstrates functions under special conditions and shows that products are ready for integration or use. • Detection: • It discovers defects, errors and deficiencies. It determines system capabilities and limitations, quality of components, work products and the system. • Prevention: • It provides information to prevent or reduce the number of errors clarify system specifications and performance. Identify ways to avoid risk and problems in the future. • Improving quality: • By doing effective testing, we can minimize errors and hence improve the quality of software. [1]
- 5. PURPOSES & IMPORTANCE OF SOFTWARE TESTING • Finding defects / bugs is one of the purposes of software testing, it is not the sole purpose. It is important for software testing to verify and validate that the product meets the stated requirements / specifications. • Testing each unit is important because all units must perform in an efficient manner. • Software testing is now a key component of software product development because it improves consistency and performance.
- 6. WHY IS TESTING NECESSARY? • Software testing is very important because software testing is really required to point out the defects and errors that were made during the development phases. • Example: programmers may make a mistake during the implementation of the software.
- 7. DIFFERENT TESTING TECHNIQUES • WHITE BOX TESTING • BLACK BOX TESTING • GRAY BOX TESTING
- 8. WHITE BOX TESTING • White-box testing also known as clear box testing, glass box testing, transparent box testing, and structural testing.[2][3] • It is highly efficient in detecting and resolving problems, because bugs can often be found before they cause trouble. • We can thus define this method as testing software with the knowledge of its internal structure and coding. • The tester has complete knowledge of how the program components interact.

- 10. GRAY BOX TESTING • It is defined as testing software and also having some knowledge of its internal logic and underlying code. • It is a technique to test the application with limited knowledge of the internal working of an application.[4] • Good to use in penetrating testing.
- 11. BY WHOM TESTING IS DONE • Testing is being done by all those who are intricate to the software development. [6] • The various professionals are indulged in testing the software: • Project Manager, Software Tester, Software Developer and End Users.
- 12. CONCLUSION • Software testing is the activity that executes software with an intention of finding errors in it. • Software testing can provide an independent view of the software to allow the business to appreciate and understand the risk of software implementation.
