- 1. What Exactly are the Techniques of Software Verification and Validation A Storehouse of Vast Knowledge on Software Testing and Quality Assurance
- 2. Areas Covered Software Verification and Validation When Combined Together Are Abbreviated as V & V
- 3. What does these Two Provide Verification Ensures that: Every Step in the Process of Building the Software Delivers the Correct Product Validation Ensures that: Software Being Developed or Changed Satisfies Functional and All Other Requirements
- 4. What Kind of Verification Do we Have ? Firstly Let Us Understand
- 5. Major Categories of Verification • Dynamic Testing • Static Testing There are Two Major Categories of Verification Testing:
- 6. Dynamic Testing Firstly Let Us Go Deeper Into
- 7. Dynamic Testing - A Type of Verification • Involves Execution of a System or Component • Selection of a Group of Test Cases Consisting of Test Data • Finding out Output Test Results out of Input Test Cases What Does Dynamic Testing Do ?
- 8. Dynamic Testing - A Type of Verification • Functional Testing • Structural Testing • Random Testing Sub Categories of Dynamic Testing
- 9. Sub Categories Dynamic Testing • Involves Identification & Testing of all Functions of the System as Defined in Basic Requirements Documents • It is a Black Box Testing Not Expecting that the Tester should have any Knowledge of the Basic Code & Implementation of the System Functional Testing: A Type of Dynamic Testing
- 10. Sub Categories Dynamic Testing • It uses Test Cases Designed to Investigate Certain Feature of the System Functional Testing: A Type of Dynamic Testing
- 11. Sub Categories Dynamic Testing • It is a White Box Testing Expecting Full knowledge of the Implementation of the System • Information of the Internal Structure of the System is Used to Design Tests for Checking the Function of Individual Components Structural Testing: A Type of Dynamic Testing
- 12. Sub Categories Dynamic Testing • Like Functional Testing, it also uses Test Cases Designed to Investigate Certain Feature of the System Structural Testing: A Type of Dynamic Testing
- 13. Sub Categories Dynamic Testing • Uses Free Selection of Test Cases out of a set of All Possible Test Cases • Uses Randomly Decided to Detect Faults which Go Undetected by Other Systematic Testing Techniques Random Testing: A Type of Dynamic Testing
- 14. Sub Categories Dynamic Testing • Exhaustive Testing is a Form of Random Testing, Involving Input Test Cases having Every Possible Set of Input Values • Although We do Exhaustive Testing at Every Stage of Life Cycle, Complete Verification of the System, is not Possible & Realistic Random Testing: A Type of Dynamic Testing
- 15. Static Testing Secondly Let Us Go Deeper Into
- 16. • Does not Involve Operation of the System or Component • Involves Manual as well as Automated Testing Techniques Attributes of Static Testing Static Testing - A Type of Verification
- 17. Static Testing - A Type of Verification • Consistency Techniques : Meant for Doing Analysis of Consistency • Measurement Techniques : Meant for Doing Measurement of Some Property of the Program Sub Categories of Static Testing
- 18. Static Testing - A Type of Verification Ensures Correctness of Program Properties Like: # Correct Syntax # Correct Parameter Matching Between Procedures Consistency Techniques of Static Testing
- 19. Static Testing - A Type of Verification Ensures Correctness of Program Properties Like: # Correct Typing # Correct Requirements and Translation of Specifications Consistency Techniques of Static Testing
- 20. Static Testing - A Type of Verification Measures the System Properties Like: # Being Error Prone # Being Understandable # Being Well Structured Measurement Techniques of Static Testing
- 21. What is All About Validation Testing ? Secondly Let Us Understand
- 22. When Does Validation Come into Picture • It Views the Complete System Exactly Opposite of Verification • It Focuses on Smaller Sub-Systems Validation comes Into Picture at the End of the Development Cycle
- 23. What are the Techniques of Validation Testing ?
- 24. Techniques of Validation Testing • Besides being a Verification Technique it is a Validation Technique as well • Involves use of Mathematical and Logical Techniques to: Express, Investigate, & Analyze the Specification, Design, Documentation and Behavior of Hardware as well as Software Formal Methods : A Technique of Validation Testing
- 25. Techniques of Validation Testing Is an Intentional Activation of Faults by Either Hardware or Software to Observe the System Operation under such Faulty Situations Fault Injection : A Technique of Validation Testing
- 26. Techniques of Validation Testing Also known as Physical Fault Injection since Faults are Injected into the Physical Hardware Hardware Fault Injection : A Technique of Validation Testing
- 27. Techniques of Validation Testing • Involves Injection of Errors into the Computer Memory through some Software Techniques • It is a sort of a Simulation of Hardware Fault Injection Software Fault Injection : A Technique of Validation Testing
- 28. Techniques of Validation Testing Involves Identification of Hazards and Subsequently Proposing Methods to Reduce the Risk of the Hazards Dependency Analysis : A Technique of Validation Testing
- 29. Techniques of Validation Testing Involves using Instructions to Identify Hazards, Their Root Causes, and Possible Countermeasures Hazard Analysis : A Technique of Validation Testing
- 30. Techniques of Validation Testing Goes Beyond Hazard Analysis by Identifying the Possible Consequences of Each Hazard and Their Probability of Occurrence Risk Analysis : A Technique of Validation Testing
- 31. Pros & Cons of Verification & Validation • Verification and Validation are Quite Time Consuming Processes • They Involve Planning from the Beginning, the Development of Test Cases, Actual Testing, and Analysis of Testing Results • Best Practice is to have Persons Dedicated to V & V and made to operate with the Designers
