 ```typescript
-import { testWithII } from "@dfinity/internet-identity-playwright";
+import { initSatelliteSuite } from "@junobuild/emulator-playwright";
+import { test } from "@playwright/test";
 
-testWithII("should sign-in with a new user", async ({ page, iiPage }) => {
-  await page.goto("/");
+const getPages = initSatelliteSuite();
 
-  await iiPage.signInWithNewIdentity();
+test("...", async () => {
+  const { satelliteId, cliPage } = getPages();
 });
