Genotoxic Mutation Testing Triage FAQs

Question 1

What is mutation testing in the context of this skill?

Accepted Answer

Mutation testing involves introducing small bugs (mutants) into your code to see if your tests catch them. If a test passes despite the change, the mutant has 'survived,' indicating a potential gap in your test suite.

Question 2

Why is Trailmark required for Genotoxic?

Accepted Answer

Trailmark provides the code graph analysis necessary to understand the context of a mutant, such as whether it's in dead code, a high-complexity function, or reachable from a public API.

Question 3

What are 'corroborated' findings?

Accepted Answer

A corroborated finding occurs when both mutation testing and necessist flag the same function, indicating a very high-confidence weakness in the code's verification.

Question 4

How does this skill help with fuzzing?

Accepted Answer

It identifies 'Fuzzing Targets' by finding functions with high cyclomatic complexity and wide blast radii that are reachable from external entrypoints but lack robust test coverage.

Question 5

What does the 'necessist' tool do?

Accepted Answer

Necessist finds 'unnecessary' test statements—lines in your tests that can be removed without causing the test to fail—which highlights weak assertions that aren't actually verifying behavior.
