How do testing metrics like defect density and test coverage contribute to assessing the quality of software?

Discuss the importance of unit testing and integration testing in the software development process. How do they contribute to code reliability?

You have become familiar with a variety of black box testing techniques, such as performance testing, stress testing, volume testing, and others. Please investigate if software testing technologies are suitable in this case. At least two software testing tools must be mentioned that can quickly and effectively carry out software performance testing.

Describe the concept of "Technical Debt" in software development. How does it affect software quality, and what strategies can be employed to manage and reduce technical debt?

You have been instructed by your professors in black box testing techniques such as stress and volume testing. Please review the software testing technologies that are acceptable for this work. For software performance testing, at least two software testing tools must be briefly introduced.
