## Features
### Org view: browse repositories for a GitHub organization
### Topic view: browse repositories for a GitHub topic
### Repo view: dive into a single repository
#### Overview: test statistics, including test files, test helpers, and CI tests
#### Test Location: file tree chart showing where tests are located
#### Test History: test metrics across releases
#### Test Dependencies: dependencies related to testing (from [GitHub SBOM](https://docs.github.com/en/rest/dependency-graph/sboms))
Files are automatically classified into categories: `test`, `test-helper`, `e2e`, `mock`, `snapshot`, `fixture`, `benchmark`, `smoke`, `ci-test`, and `source`.
## Usage
Just open [testminer](https://andrehora.github.io/testminer) and search by:
- repository (e.g. `https://github.com/fastapi/fastapi`, or simply `fastapi/fastapi`)
- organization/user (e.g. `google`, `microsoft`)
- topic (e.g. `ai`, `llm`, `api`)
### GitHub Token
Without a token, the GitHub API allows 60 requests/hour. Adding a read-only personal access token increases this to 5,000/hour. The token is stored only in your browser's `localStorage`.
## Development
npm run dev # Start dev server (Vite)
npm test # Run unit tests (Vitest)
npm run e2e # Run end-to-end tests (Cypress)
