Interview Questions

What is the MAIN benefit of designing tests early in the life cycle?
It helps prevent defects from being introduced into the code.

What is risk-based testing?
Risk-based testing is the term used for an approach to creating a test strategy that is based on prioritizing tests by risk. The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first.

What is the KEY difference between preventative and reactive approaches to testing?
Preventative tests are designed early; reactive tests are designed after the software has been produced.

What is the purpose of exit criteria?
The purpose of exit criteria is to define when a test level is completed.

What determines the level of risk?
The likelihood of an adverse event and the impact of the event determine the level of risk.

When is used Decision table testing?
Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations. In a decision table the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced.
