AI-Powered Testing: Generate, Run, and Maintain Test Suites
Tests are the threshold between AI-generated code and shipped code. Generate coverage, spot blind spots, and keep suites alive with AI in the loop.

AI writes tests fluently — and can bog a suite down with tests that all assert the same thing. The skill is directing generation: coverage-first, behaviour-aware, and always under a human's definition of 'correct'.
Prompt for Coverage, Then Read the Coverage Map
Ask the model for tests over the boundary cases, not the happy path it favours: 'test empty input, unusual values, and failure paths'. Then run the coverage tool and eyeball the red zones — the AI's blind spots are usually your most fragile branches. The generator in Cursor Pro turns that loop into a fast cycle.
Keep the Assertions Meaningful
AI-generated tests often assert implementation details, freezing code that should refactor. Review assertions against behaviour — what the function promises, not how it's built. Mismatched expectations get caught when verification habits meet the suite on a CI run.
Use Second Opinions on Troubled Tests
When a test suite is chronically red, have a different model critique strategy — Claude API reviewing the suite for overlapping coverage and brittle assertions (see prompt maintenance for the versioned prompt angle). Tests that were generated but never understood are how suites die; review is how they live.

Final Thoughts
AI tests speed coverage but not judgement: prompt for boundaries, assert behaviour, and challenge brittle suites with a second model. Human review at the threshold keeps the suite honest.
