11.1The Tool Landscape for AI Test Writing
Claude Code is not the only option. GitHub Copilot and Cursor are two widely-used alternatives, each with different strengths. Understanding when to use each tool is a practical skill that interviewers value.
A note on the models underneath: as of July 2026, the frontier models these tools run on are Claude Opus 4.8 (the current coding leader), OpenAI GPT-5.5, and Google Gemini 3.1 Pro. Copilot and Cursor both let you pick among frontier models, so the tool choice is increasingly about workflow shape (inline completion vs. interactive iteration vs. autonomous agent), not raw model quality.
