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.
