To run all tests in a headless Chromium browser and display results in the terminal. This assumes you have Grafana running on port 3000.
The following script starts a Grafana [development server](https://github.com/grafana/grafana/blob/main/scripts/grafana-server/start-server) (same server that is being used when running e2e tests in CI) on port 3001 and runs all the Playwright tests. The development server is provisioned with the [devenv](https://github.com/grafana/grafana/blob/main/contribute/developer-guide.md#add-data-sources) dashboards, data sources and apps.

The following script starts a Grafana [development server](https://github.com/grafana/grafana/blob/main/scripts/grafana-server/start-server) (same server that is being used when running e2e tests in Drone CI) on port 3001 and runs the Playwright tests. The development server is provisioned with the [devenv](https://github.com/grafana/grafana/blob/main/contribute/developer-guide.md#add-data-sources) dashboards, data sources and apps.
You can run against an arbitrary instance by setting the `GRAFANA_URL` environment variable:
```
yarn e2e:playwright:server
GRAFANA_URL=http://localhost:3000 yarn e2e:playwright
```
Note this will not start a development server, so you must ensure that Grafana is running and accessible at the specified URL.
## Configure Grafana for development
The default configuration, `defaults.ini`, is located in the `conf` directory.
