AI for Testing: Keep It Simple and Solid

Tests protect your work. AI can write drafts fast, but you decide what’s worth keeping.

Good tests are small

• One behavior per test
• Clear arrange/act/assert
• No hidden magic or random sleeps

What to ask AI

• “Write 3 tests for these edge cases. Keep them short.”
• “Convert this flaky test into a stable version.”
• “Suggest realistic data and boundary values.”

Don’t overdo it

• Many tiny tests > one giant test
• Favor fast unit tests; add a few E2E for happy path
• Delete tests that only duplicate other tests

Common mistakes

• Letting AI generate hundreds of tests you won’t maintain
• Skipping assertions that matter
• Testing implementation details instead of behavior

Key takeaways

• Use AI for test ideas and first drafts
• You pick the final set, you own the quality
• Keep tests clear, fast, and meaningful
