Why AI Agents That Keep Rewriting Tests May Be a Red Flag

Key Info

A developer observes that AI coding agents often modify tests as they work, even though good tests rarely change—meaning the agent may be writing the same code twice. They plan to experiment by banning agents from creating tests.

Highlights

  • Good tests are stable; frequent test changes by agents can signal redundant work.
  • Agents may effectively write the same code twice—once in implementation, once in tests.
  • The author is considering banning agent-generated tests to redirect saved time toward product development.
