Cost of Bug What is a Bug (or Defect or Error)? Any undesired behavior is a bug Any deviation from specs / requirement is a bug Any behavior which is “not written / mentioned” in specs is a bug Cost of bug is difficult to calculate: Cost of having QA team(s) Cost of having Application engineers Cost of losing face in front of end user

“Throw it over the wall” What is a throw it over the wall ? "Throw it over the wall" is a business slang for completing your part of a project and then passing it off to the next group without testing or without sufficient testing.

Different Types of Testing Unit Testing Integration Testing System or Functional Testing Regression Testing Performance Testing Installation And the list goes on...

Regression – What is Regression testing In short regression testing is a type of testing to make sure that the changes or fixes done in the software does not break same part or any other part of the software. Regression can be employed at various levels / components of a software. Regression implementation can be manual or automated. It is highly desirable to have regression automated. Different tool(s) / language can be used to implement regression
