It helps prevent defects from being introduced into the code.

To identify defects in any software work product.

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.

Risk-based 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.

Preventative tests are designed early; reactive tests are designed after the software has been produced.

It avoids author bias in defining effective tests.

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

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