+# How to run tests
+
+First start the servers:
+
+```bash
+// ESS
+node scripts/scout.js start-server --stateful
+
+// Serverless
+node scripts/scout.js start-server --serverless=[es|oblt|security]
+```
+
+Then you can run the parallel tests in another terminal:
+
+```bash
+// ESS
+npx playwright test --config x-pack/solutions/observability/plugins/infra/test/scout/ui/parallel.playwright.config.ts --project=local --grep @ess
+
+// Serverless
+npx playwright test --project local --config x-pack/solutions/observability/plugins/infra/test/scout/ui/parallel.playwright.config.ts --grep @svlOblt
+```
+
+Test results are available in `x-pack/solutions/observability/plugins/infra/test/scout/ui/output`
