# 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`
