Yes. AI can write unit tests for existing or newly generated code, especially when you provide the behavior, test framework, and examples from the repository. The tests still need review because generated assertions may confirm implementation details instead of real requirements.
Give the agent the target module, public contract, edge cases, and test command. Ask for tests covering valid input, boundaries, invalid states, errors, and important invariants. For a bug, require a regression test that fails before the fix and passes after it. Avoid excessive mocking that prevents the test from exercising meaningful logic.
Review whether tests can fail for the right reason. Check assertions, fixture realism, determinism, cleanup, and naming. Run coverage or mutation testing as signals, but do not treat a percentage as proof of quality. Keep integration tests for behavior that crosses databases, networks, or framework boundaries.
Verdent can generate tests through its verification workflow, while independent workers can handle stable modules in parallel. Reviewer can provide an additional review pass over the resulting changes and tests. AI is most valuable for expanding systematic coverage while a human decides which risks matter and whether the tests express the intended behavior.
