Question Title Graded Discussion (GDB)
Question Description
Regression Testing is done to ensure that a code change in the software does not impact the existing functionality of the product. However the size of the test-suite grows when new test cases are added to the test suite which increases the cost of regression testing. Regression testing requires running a large program on a large number of test cases which means it can be expensive in both human and machine time.
Suggest in your own words how can we deal with this situation. Your answer should be based on valid reasoning (maximum 5 to 6 lines).
Irrelevant and lengthy answers will result in negative marking. Copy paste answers from the Internet or other students will get zero marks.
Suppose there is a popular software company ABC that has prepared a project of billing system. To maintain its standard, testing needs to be applied on the project by the company. There are different types of testing such as white box testing, black box testing, grey box testing, functional testing, and unit testing. Different testing techniques are applied according to different suitability. If only white box testing is applied on the system, do you think it is enough for the billing system? Justify your answer with valid points considering the parameters (time, cost, quality, accuracy).
Note: Answer should be between 4-8 lines.

Question No. 2. (Marks 3.5)
Write a short note on the quality of the software and the possible ways for the improvement of software quality.
This question will be rewarded on the basis of quality of research and the writing (contents, grammar, spelling, formatting).
Software quality
Software quality is defined as the attributes of software fulfilled while designing the software that is maintaining its cost, user requirements/expectations, proper working and functionality of software, time to build a product, to make a bug free software.
Attributes of software quality
The quality of software depends on various attributes:
Design
Functionality
Performance
Consistency
Maintainability
Cost
Improvement of software quality
To improve software quality, various processes needs to be maintained:
• There should be proper planning for the project development to achieve good quality.
• Inspections and reviews must be conducted while the product is being developed.
• Defects in the product must be identified and removed before software deployment.
• Fixing the defects will lead to low budget.
