Defect Finding Techniques
Defect Finding Techniques
One of the key components of quality assurance is the identification and removal of defects (also called bugs or issues). Defect finding techniques are methods used by testers to detect flaws or errors in software applications before they reach the end users. These techniques help in maintaining the reliability, performance, and functionality of software.
What is a Defect Finding Technique?
Defect Finding Techniques are approaches used by software testers to identify issues or bugs in a software product. These techniques can be applied at different stages of the software development lifecycle and help in detecting defects early, thereby reducing the cost and effort of fixing them later.
Types of Defect Finding Techniques
- Static Technique
- Dynamic Technique
- Operational Technique
Technique | Description |
---|---|
Static Technique | This technique involves examining the code, documents, or design without executing the program. It includes activities such as reviews, walkthroughs, and inspections. Static techniques help find defects early in the development phase and are cost-effective. |
Dynamic Technique | This technique involves executing the software and observing its behavior. It includes actual test execution with input data to verify if the software behaves as expected. Functional testing, regression testing, and system testing are part of dynamic techniques. |
Operational Technique | Operational techniques involve monitoring the software during its actual use in the production environment. It helps uncover defects that may not surface during testing phases, such as performance issues or user experience problems under real-world usage. |
