software-testing13. What group of teams can do software testing?
When it comes to testing everyone in the world can be involved right from the developer to the project manager to the customer. But below are different types of team groups which can be present in a project.
Isolated test team
Outsource – we can hire external testing resources and do testing for our project.
Inside test team
Developers as testers
QA/QC team.

14. What impact ratings have you used in your projects?
Normally, the impact ratings for defects are classified into three types:
Minor: Very low impact but does not affect operations on a large scale.
Major: Affects operations on a very large scale.
Critical: Brings the system to a halt and stops the show.

15. Does an increase in testing always improve the project?
No an increase in testing does not always mean improvement of the product, company, or project. In real test scenarios only 20% of test plans are critical from a business angle. Running those critical test plans will assure that the testing is properly done. The following graph explains the impact of under testing and over testing. If you under test a system the number of defects will increase, but if you over test a system your cost of testing will increase. Even if your defects come down your cost of testing has gone up.

16. What’s the relationship between environment reality and test phases?
Environment reality becomes more important as test phases start moving ahead. For instance, during unit testing you need the environment to be partly real, but at the acceptance phase you should have a 100% real environment, or we can say it should be the actual real environment.
