- Junior engineers using LLM tools often submit untested PRs, shifting the burden to reviewers.
- Software engineers must deliver proven, working code, not just generate it.
- Manual testing is essential—demonstrate the code works before submission.
- Automated testing is now easier with LLMs and should not be skipped.
- Coding agents (e.g., Claude Code, Codex CLI) can execute and test code, but humans must ensure accountability.
- Good testing practices and taste in test code distinguish senior engineers.
