Software Testing Tutorial #41 - What is Defect in Software Testing

**Notes: What is a Defect in Software Testing - Software Testing Tutorial #41** **Defects vs. Bugs:** - "Defects" and "bugs" are often used interchangeably. - In practical scenarios, the distinction between them is rarely made. - For this tutorial, consider them to be the same. **Understanding Defects:** - In software testing, defects or bugs occur when actual results deviate from expected results. - This deviation indicates a flaw in the software. - Testers identify defects during the testing phase. **Example:** - Consider testing a login functionality on an e-commerce website. - The expected result is redirection to the dashboard page upon successful login. - If the login screen refreshes without redirection, it's a defect. **Defects Across the Software Testing Life Cycle:** - Defects can be identified at various stages of the software testing life cycle. - These stages include functional testing, acceptance testing, and even post-production deployment when customers report issues. - All deviations from expected behavior are considered defects. **Key Defect Metrics:** 1. **Critical Defect Percentage:** - Calculates the percentage of critical defects in relation to the total number of defects. - Critical defects have a severe negative impact on business or software functionality. 2. **Defect Rejection Ratio:** - Considers the number of defects rejected by the development team. - Rejected defects are those not code-related but due to testing conditions. 3. **Defect Leakage Ratio:** - Measures defects discovered after software deployment in the production environment. - Compares production defects to the total defects detected during testing. **Importance of Defect Metrics:** - Defect metrics, especially defect rejection and leakage ratios, assess testing effectiveness. - Lower ratios indicate early issue detection and fewer defects escaping to production. **Conclusion:** - Defects in software testing result from deviations in actual and expected results. - They are identified throughout the software development life cycle. - Tracking defect metrics assesses testing quality and software reliability.
