Find duplicate Playwright tests with semantic-graph

semantic-graph is a free, open-source CLI from TestChimp. It scans your Playwright-style test files, embeds each test, clusters them by meaning and opens a local graph, so you can see which tests overlap before your suite gets slower and harder to maintain.

npm package GitHub Read the guide

What it does

Scans *.spec and *.test files written with test() and test.describe().
Embeds every test and measures how similar each pair is.
Groups related tests into named clusters on a 2D map, so near-duplicates sit next to each other.
Serves a local UI with a folder tree and the graph. No database, and nothing is stored between runs.
Works with OpenAI, or with Claude plus Voyage for embeddings.

Install and run

Run it against your tests folder

export PROVIDER=openai
export API_KEY=sk-...

npx @testchimp/semantic-graph visualize --tests-dir ./tests

Using Claude? Set PROVIDER=anthropic, put your Anthropic key in API_KEY and add a VOYAGE_API_KEY for embeddings. The CLI prints a local URL (port 3859 by default) when the graph is ready.

More open-source tools

ai-wrightVision-based ai.act, ai.verify and ai.extract steps inside standard Playwright tests.

Keep your suite free of duplicates as it grows

semantic-graph gives you a one-off local view. TestChimp runs duplicate detection continuously, alongside requirement traceability and release checks, so your suite stays healthy as agents add tests.
