+Feature: Authenticator Component for Svelte
+
+  Amplify UI Authenticator provides a complete authentication flow for Svelte applications.
+
+  Background:
+    Given I'm running the example "ui/components/authenticator/svelte"
+
+  @svelte @react @vue @angular
+  Scenario: Sign in with valid credentials
+    When I type my "username" with status "CONFIRMED"
+    And I type my password
+    And I click the "Sign in" button
+    Then I see "Sign out"
+
+  @svelte @react @vue @angular
+  Scenario: Sign in with wrong credentials
+    When I type my "username" with status "CONFIRMED"
+    And I type an invalid password
+    And I click the "Sign in" button
+    Then I see "Incorrect username or password"
+
+  @svelte @react @vue @angular
+  Scenario: Sign up a new user
+    Given I intercept '{ "headers": { "X-Amz-Target": "AWSCognitoIdentityProviderService.SignUp" } }' with fixture "sign-up-with-email"
+    When I click the "Create Account" tab
+    And I type a new "username"
+    And I type my password
+    And I confirm my password
+    And I type my "email" with value "test@example.com"
+    And I click the "Create Account" button
+    Then I see "Confirm Sign Up"
+
+  @svelte @react @vue @angular
+  Scenario: Confirm sign up
+    Given I intercept '{ "headers": { "X-Amz-Target": "AWSCognitoIdentityProviderService.ConfirmSignUp" } }' with fixture "confirm-sign-up-success"
+    And I'm at the "Confirm Sign Up" page
+    When I type a valid confirmation code
+    And I click the "Confirm" button
+    Then I see "Sign In"
+
+  @svelte @react @vue @angular
+  Scenario: Reset password
+    When I click the "Forgot your password?" button
+    Then I see "Reset your password"
+    When I type my "username" with status "CONFIRMED"
+    And I click the "Send Code" button
+    Then I see "Reset your password"
+
+  @svelte @react @vue @angular
+  Scenario: Force new password flow
+    When I type my "username" with status "FORCE_NEW_PASSWORD"
+    And I type my password
+    And I click the "Sign in" button
+    Then I see "Change Password"
+
+  @svelte @react @vue @angular
+  Scenario: Setup TOTP flow
+    When I type my "username" with status "TOTP_SETUP"
+    And I type my password
+    And I click the "Sign in" button
+    Then I see "Setup Two-Factor Authentication"
+
+  @svelte @react @vue @angular
+  Scenario: Sign in with federated provider
+    Given "google" login is enabled
+    Then I see the "Sign in with Google" button
+
+  @svelte @react @vue @angular
+  Scenario: Hide sign up
+    Given "hideSignUp" is enabled
+    Then I don't see "Create Account"
+
+  @svelte @react @vue @angular
+  Scenario: Custom slot content when authenticated
+    When I type my "username" with status "CONFIRMED"
+    And I type my password
+    And I click the "Sign in" button
+    Then I see "Hello testuser"
