The basic knowledge problem of software testing

11, pressure test and load test?

Load test: Usually the running time is relatively short, gradually pressurized on the system, until the performance index saturation (such as the corresponding time exceeded the expected requirements, high system resource occupancy, etc.), so as to verify the system expected performance objectives, the corresponding time and so on.

Stress testing: long-running, increasing overload (concurrency, loops, multiuser, etc.) until the system generates anomalies and the ability to handle anomalies, thus verifying system reliability and finding bottlenecks in the system. * * The experience value of Microsoft stress testing is 72 hours. **

12. What is regression testing ?

　　regression testing: After defect correction, execute test cases that meet certain criteria to ensure that bug fixes do not introduce new flaws in the software, which may exist in the software modules being tested or in other software modules that are relevant or unrelated to them. regression testing is required when the software changes or the environment in which the software is used is changed

13. Describe the life cycle of the bug ?

1, effectively record bugs

2, using the bug template

3, evaluating bug priority and severity

4, Bug's life

5, maintaining the bug database

14. What should be included in the defect record?

Defect identification, defect type, defect severity, defect generation probability, defect priority, defect status, origin of defect, source of defect, cause of defect;
