1.1.2 Testing and Debugging

Question 1

Testing can trigger

Answer 1

failures that are caused by defects in the software (dynamic testing) or can directly find defects in the test object (static testing).

Question 2

Answer 2

Question 3

Answer 3

• Reproducing of a failure
• Diagnosis (finding the defect)
• Fixing the defect

Question 4

Confirmation testing

Answer 4

Checks whether the fixes resolves the problem.
Preferably, should be done by the same person who performed by the initial test.

Question 5

Regression testing

Answer 5

Can also be performed to check whether the fixes are causing failures in other parts of the test object.

Question 6

Static testing and debugging

Answer 6

When static testing identifies a defect, debugging is concerned with removing it.

No need for reproduction or diagnosis, since static testing directly, finds defects and can’t cause failures.
