name: clerk-auth-e2e-testing-only description: Programmatic Clerk sign-in for e2e testing. Use when the application authenticates with Clerk and you need to sign in test users (including multi-user scenarios) without interacting with the Clerk UI. Note this only works for applications built with Replit's Clerk Authentication support.

Clerk Auth E2E Testing Only

Sign in Clerk users programmatically for e2e tests. Use the signInClerkUser function only — do not interact with the Clerk UI directly.

Available Functions (from ExecutePlaywrightAction)

async function signInClerkUser(
  signInOptions: {
    firstName: string;
    lastName?: string;
    email: string;
    ttl?: number; // TTL in seconds (default: 3600)
    basePath?: string; // Relative URL path appended to the dev domain for the post-sign-in redirect
  }
): Promise<string>

This function is in scope of the code for ExecutePlaywrightAction and can be used directly without any registration.

It returns a sign-in URL; navigate a page to that URL to inject the sign-in session.

Usage

Sign in a single user

const signInUrl = await signInClerkUser({
  firstName: "Test",
  lastName: "User",
  email: "testuser@example.com",
});
// Navigate to the returned sign-in URL to inject the sign-in session.
await page.goto(signInUrl);

Sign in for an artifact in a pnpm workspace

When testing an artifact served under its own preview path (e.g. in a multi-artifact or pnpm workspace repl), set basePath to the artifact's preview URL so the sign-in session redirects to the correct artifact.

// Set basePath to the artifact's preview path so Clerk redirects there after sign-in
const signInUrl = await signInClerkUser({
  firstName: "Test",
  lastName: "User",
  email: "testuser@example.com",
  basePath: "/my-app/",
});
await page.goto(signInUrl);

Sign in multiple users in independent browser contexts

const context = await newBrowserContext({ /* context options */ });
context.setDefaultTimeout(3000);
const newPage = await context.newPage();
const signInUrl = await signInClerkUser({
  firstName: "Bob",
  lastName: "Test",
  email: "bobtest@example.com",
});
await newPage.goto(signInUrl);

Test Plan Examples

• [Clerk] Sign in admin@example.com programmatically and navigate to the returned sign-in URL
• [Browser] Verify the admin dashboard appears
• [Clerk] Sign in a second user in a new browser context
• [Browser] Verify both users see their own data

Notes

• Sessions are scoped to the browser context whose page navigates to the sign-in URL
• Do not interact with the Clerk UI (sign-in forms, modals) — only use signInClerkUser
• The default session TTL is 3600 seconds; pass ttl to change it
