# Test plugins The [e2e test server](https://github.com/grafana/grafana/blob/main/scripts/grafana-server/start-server) automatically scans and looks for plugins in this directory. ### To add a new test plugin: 1. If provisioning is required you may update the YAML config file in [`/devenv`](https://github.com/grafana/grafana/tree/main/devenv). 2. Add the plugin ID to the `allow_loading_unsigned_plugins` setting in the test server's [configuration file](https://github.com/grafana/grafana/blob/main/scripts/grafana-server/custom.ini). ### Building a test plugin with webpack If you wish to build a test plugin with webpack, you may take a look at how the [grafana-extensionstest-app](./grafana-extensionstest-app/) is wired. A few things to keep in mind: - the package name needs to be prefixed with `@test-plugins/` - extend the webpack config from [`@grafana/plugin-configs`](../../packages/grafana-plugin-configs/) and use custom webpack config to only copy the necessary files (see example [here](./grafana-extensionstest-app/webpack.config.ts)) - keep dependency versions in sync with what's in core #### Local development 1: Install frontend dependencies: `yarn install --immutable` 2: Build and watch the core frontend `yarn start` 3: Build and watch the test plugins `yarn e2e:plugin:build:dev` 4: Build the backend `make build-go` 5: Start the Grafana e2e test server with the provisioned test plugin `PORT=3000 ./scripts/grafana-server/start-server`
