Which is NOT a purpose of using test tools?

The goal of using test tools is typically centered around enhancing the efficiency and effectiveness of testing processes. Improving the efficiency of test activities allows for quicker test execution, better resource management, and more timely feedback on software quality. Reducing the need for manual testing processes emphasizes automating repetitive tasks, which can lead to increased productivity and focus on complex testing scenarios. Increasing the reliability of testing is achievable through consistent execution of tests with tools, which tend to minimize human error and enforce standardized testing procedures.

Choosing an option that indicates an increase in software costs does not align with the fundamental purpose of testing tools. In fact, effective use of test tools is usually intended to reduce overall costs by streamlining processes and catching defects early in development, which can ultimately lead to less expensive fixes down the line.
