Which of the following is a potential source of bias in fault seeding?

Using automated tools to insert faults

Seeding faults that are too easy to find

Running the test suite multiple times

Involving testers in the seeding process

Which of the following sequences correctly describes the fault seeding process?

Analyze results, introduce seeded faults, run tests, estimate remaining defects

Estimate remaining defects, introduce seeded faults, run tests, analyze results

Run tests, introduce seeded faults, analyze results, estimate remaining defects

Introduce seeded faults, run tests, analyze results, estimate remaining defects

A test team is preparing to seed faults into a web application. The application has a history of defects in authentication and input validation. Which set of seeded faults would be most appropriate for estimating remaining defects?

Faults in authentication and input validation logic, along with a few typical off-by-one errors.

Faults that are extremely difficult to find, to challenge the test team.

Faults that are already known to exist in the code, to avoid introducing new issues.

Faults only in the user interface, since they are easiest to detect visually.

What is a key limitation of fault seeding?

It eliminates the need for code reviews

It requires a large number of testers to be effective

It can only be used for unit testing

It assumes that seeded faults are distributed similarly to real faults

What is the first step in the fault seeding process?

Estimating the total number of defects in the software

Introducing known faults into the software

Analyzing the results to identify undetected faults

Running the test suite to establish a baseline
