I've seen reasonable results from letting Claude Code apply test driven development and having a good e2e test suite on top of that (with Playwright). In that setup giving it Playwright MCP to access the app and verify why e2e tests are working or not working, and for writing new tests helps.

Just giving it an MCP to test changes also didn't work for me. But the combination with e2e tests was better.
