10 Questions
What is the main purpose of program testing?
To demonstrate that the program does what it is intended to do and to uncover defects
What is the primary goal of defect testing?
To expose defects in the software
Which process is concerned with exercising and observing product behavior?
Software testing
What distinguishes validation testing from defect testing?
Validation testing reflects the system's expected and normal use, while defect testing is designed to expose defects.
What advantage does inspection have over testing in terms of error detection?
'During testing, errors can mask (hide) other errors.' Because inspection is a static process, you don’t have to be concerned with interactions between errors.
Explain the difference between validation testing and defect testing in the context of software testing.
Validation testing is intended to demonstrate that the software meets its requirements, while defect testing is designed to expose defects in the software's behavior.
What are the goals of the testing process according to the text?
The goals of the testing process include validation testing, defect testing, verification ('Are we building the product right?'), and validation ('Are we building the right product?').
Describe the focus of software inspections and software testing.
Software inspections focus on the static system representation to discover problems (static verification), while software testing focuses on exercising and observing product behavior (dynamic verification).
Explain how errors can mask other errors during testing and how inspections address this issue.
During testing, errors can hide other errors, but because inspection is a static process, it doesn't have to be concerned with interactions between errors, allowing for a more thorough analysis.
What is the primary purpose of program testing according to the text?
The primary purpose of program testing is to show that a program does what it is intended to do, discover program defects before its use, and demonstrate to the developer and customer that the software meets its requirements.
Study Notes
Program Testing
- The main purpose of program testing is to detect errors in a program.
- The primary goal of defect testing is to identify defects in a program.
- Testing is concerned with exercising and observing product behavior.
Validation and Defect Testing
- Validation testing is concerned with ensuring that the software meets the user's requirements and expectations.
- Defect testing is concerned with identifying defects in the software.
- Validation testing is different from defect testing in that it ensures the software meets user requirements, whereas defect testing focuses on identifying defects.
Error Detection
- Inspection has an advantage over testing in terms of error detection because it can detect errors early in the development process.
- Errors can mask other errors during testing, making it difficult to detect them.
- Inspections address this issue by detecting errors early, before they are masked by other errors.
Testing Process
- The goals of the testing process are to detect errors, identify defects, and ensure the software meets user requirements.
Software Inspections and Testing
- Software inspections focus on detecting errors early in the development process.
- Software testing focuses on exercising and observing product behavior to identify defects.
- Inspections are a more effective way to detect errors than testing, as they can detect errors early and prevent them from being masked by other errors.
