A Correct answer
Explanation

Debugging is the systematic process of identifying, isolating, and fixing errors or bugs in software code. It involves testing, tracing execution, and correcting defects to ensure programs function correctly.

Multiple choice

Which of the following is not the characteristic of good test data?

  1. Users do not participate at this preliminary stage.

  2. It should be comprehensive.

  3. Every statement should be executed.

  4. Expected output from the modules execution should be determined manually.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Good test data should be comprehensive and help verify all system paths. User participation is actually highly recommended during testing to ensure the system meets business requirements, making option A the incorrect characteristic.

Multiple choice

Many aircraft maintenance and repair companies use sophisticated computer diagnostic techniques, in addition to actual physical inspections, in order to determine which repairs are necessary. Aircraft owners, like airlines, however, are reluctant to pay the extra costs involved for the computer tests, thereby decreasing the quality of service that they receive.

In order for the conclusion above to be valid, which one of the following is a necessary assumption?

  1. Physical inspections and expensive computer tests combined, provide a more accurate diagnosis of aircraft problems than do inspections alone.

  2. Many aircraft repair technicians oppose price cuts that limit their use of computer diagnostics.

  3. Many customers who could benefit from the computer tests cannot afford them.

  4. Some aircraft problems could be diagnosed by physical examination alone.

  5. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This must be true for the argument to stand up. Quality of service the owners receive would decrease only if it is true that the addition of the computer test provides a more accurate diagnosis than do the inspections alone.
