What can a risk-based approach to testing provide?

A risk-based approach to testing focuses on identifying and assessing risks associated with the software being tested. By prioritizing testing efforts based on the potential impact and likelihood of those risks, it allows teams to determine the types of test techniques that are most appropriate to address the identified risks.

For instance, areas of the software that are deemed to have higher risks may leverage more detailed and rigorous testing techniques, such as exploratory testing or performance testing, to ensure that significant issues are identified early. Conversely, lower-risk areas may require less intensive techniques. This strategic alignment of testing techniques with risk levels fosters efficient resource allocation and improves overall testing effectiveness.

The other options do not accurately reflect the advantages of a risk-based approach. While it may inform cost estimations and address test execution effectiveness, the primary benefit here is the tailored selection of test techniques based on risk assessment rather than a blanket statement about testing coverage or cost estimation.
