Claude Code vs Cursor: writing tests with AI
Choose Claude Code when you want to hand off the job: it reads the codebase, writes the tests, runs them in your terminal, fixes what fails and can open the pull request. Choose Cursor when you would rather stay in your editor and review each change as it lands, since it is built on VS Code and keeps your extensions and shortcuts. Cursor has a free plan; Claude Code needs a paid Claude subscription, which starts at $20 a month.
Which one to pick
You want to say "add tests for the billing module and make them pass" and come back to a finished branch, working from the terminal, an IDE or the web.
You live in VS Code, want to try AI test writing for free and prefer to accept or reject each multi-file change from inside the editor.

Questions
Does Cursor's free plan beat Claude Code's $20 entry price?
Cursor's free plan lets you try it on a real project before paying. Claude Code has no free plan: it comes with paid Claude plans, starting at $20 a month. Claude Code and Cursor charge in US dollars. If you already pay for Claude, Claude Code adds nothing to the bill.
Which one runs the tests it writes?
Both can run commands, so both can execute your test runner and read the failures. Claude Code is built around that loop: write, run, fix, repeat until the suite passes, then open a pull request. Cursor's agent does the same inside the editor, where you watch each step and approve the edits.
Can I use them together?
Yes, they combine well. Claude Code runs in your terminal and in IDEs, so you can launch it inside Cursor's built-in terminal. Use Cursor for quick edits and inline suggestions, and Claude Code for larger test-writing tasks you want to delegate.
Which suits a solo developer and which a team?
Both list support from solo developers to large teams. A solo developer on a budget gets more from Cursor's free plan at first. Teams that want a branch with tests and a pull request ready for review tend to fit Claude Code, because it handles the whole task and leaves the review to people.
Will switching from VS Code to Cursor break my setup?
Cursor is built on VS Code, so your extensions, settings and keyboard shortcuts carry over. The switch takes minutes for most projects. Claude Code needs no editor switch at all, since it works in your terminal next to whichever editor you already use.
