Do These Books Still Matter When AI Agents Write Test Code?

Yes. AI coding agents such as GitHub Copilot and Cursor can generate a test script in seconds, but they still depend on a person to decide what the test should check and why it matters, which is exactly the judgment these books teach.

GitHub Copilot and Cursor work by predicting code from the surrounding file and a natural-language prompt. Point either one at a function and it drafts a unit test that compiles and runs.

The real limitation is oracle selection, not syntax. An agent can write an assertion, but it cannot decide on its own which behavior is worth checking, so it will test that a function runs without checking that the output is correct for the business rule involved.

Cem Kaner and Rebecca Fiedler's Bug Advocacy teaches exactly that judgment: how to decide a bug is worth reporting and build a case a developer will act on. No coding agent replaces that reasoning, because it depends on product context the agent was never given.

The same gap shows up in A Practical Guide to Testing in DevOps, where the discipline is choosing which checks belong in a pipeline, not writing the checks themselves.

An AI agent shortens the time to a working test. It does not shorten the time to knowing which test is worth writing, which is still the skill this list of books teaches.
