E2E Role-Based Testing Skill

E2E Role-Based Testing Skill

Overview

This skill executes comprehensive role-based E2E testing using Playwright MCP. It tests all pages and flows for each user role, verifying proper access control and role-specific functionality.

Standard Test Plan Location

Plan file: tests/​e2e-test-plan.md

This skill reads role definitions and test credentials from the test plan at tests/​e2e-test-plan.md. If the plan file doesn't exist, the calling command should invoke the e2e-test-plan skill first to generate it.

Purpose

Ensure that:

• Each user role can access appropriate resources
• Unauthorized access is properly blocked
• Role-specific features work correctly
• Cross-role security is maintained

Workflow

Step 0: Test Plan Verification (REQUIRED FIRST)

CRITICAL: Before testing roles, verify the test plan exists.

1. Check for Test Plan

   • Look for tests/​e2e-test-plan.md
   • If the file exists, read the "User Roles" and "Test Credentials" sections
   • If the file does NOT exist, STOP and report that the plan must be generated first

2. Read Role Information from Plan

   • Extract role names and descriptions
   • Extract test credentials for each role
   • Extract role-resource access matrix
   • Use this information for testing

Step 1: Prepare Role Testing

1. Identify All Roles

   • List all user roles in the system
   • Note the role hierarchy
   • Map permissions per role

2. Prepare Test Users

   • Identify login credentials for each role
   • Ensure test users exist
   • Note any role-switching mechanisms

3. Map Role-Resource Matrix

   | Resource | Guest | User | Admin |
   |----------|-------|------|-------|
   | /​home | Yes | Yes | Yes |
   | /​dashboard | No | Yes | Yes |
   | /​admin | No | No | Yes |
   

Step 2: Guest Role Testing

Test unauthenticated access:

1. Public Pages

   browser_navigate to each public page
   browser_snapshot to verify content
   Confirm: Page loads correctly
   

2. Protected Page Blocking

   browser_navigate to protected page
   browser_snapshot to check result
   Confirm: Redirect to login OR 403 page
   

3. Guest-Specific Features

   Test: Registration form accessible
   Test: Login form accessible
   Test: Password reset accessible
   

Step 3: Authenticated Role Testing

For EACH authenticated role:

1. Login as Role

   browser_navigate to /​login
   browser_fill_form with role credentials:
     - fields: [
         { name: "Email", type: "textbox", ref: "[email-input-ref]", value: "[email protected]" },
         { name: "Password", type: "textbox", ref: "[password-input-ref]", value: "password" }
       ]
   browser_click on submit button
   browser_wait_for dashboard or success indicator
   browser_snapshot to verify logged in
   

2. Test Accessible Pages

   For each page this role SHOULD access:
     browser_navigate to page URL
     browser_snapshot
     browser_console_messages to check for errors
     Verify: Page content loads correctly
     Verify: Role-specific elements present
   

3. Test Blocked Pages

   For each page this role should NOT access:
     browser_navigate to page URL
     browser_snapshot
     Verify: 403 error OR redirect occurs
     Verify: No unauthorized data exposed
   

4. Test Role-Specific Actions

   For each action this role can perform:
     Navigate to action page
     Perform the action
     Verify success
   
   For each action this role CANNOT perform:
     Attempt the action
     Verify it's blocked
   

5. Logout

   browser_click logout button
   browser_wait_for login page
   browser_snapshot to confirm logged out
   

Step 4: Role-Specific Flow Testing

User Role Flows

## User Role Tests

### Profile Management
1. Navigate to /​profile
2. Verify can view own profile
3. Edit profile information
4. Save changes
5. Verify changes persisted

### Data Access
1. Navigate to /​my-data
2. Verify can see own data only
3. Cannot see other users' data
4. Can create new data
5. Can edit own data
6. Can delete own data

### Restricted Areas
1. Cannot access /​admin
2. Cannot access /​admin/​users
3. Cannot modify other users

Admin Role Flows

## Admin Role Tests

### User Management
1. Navigate to /​admin/​users
2. View all users list
3. Create new user
4. Edit existing user
5. Delete user (not self)
6. Change user roles

### System Settings
1. Access settings page
2. Modify configurations
3. Save changes
4. Verify persistence

### Admin-Only Features
1. Access reports
2. View audit logs
3. Manage permissions

Step 5: Cross-Role Security Tests

1. Session Hijacking Prevention

   Login as User A
   Copy session info
   Try to access User B data
   Verify: Access denied
   

2. Privilege Escalation Prevention

   Login as regular user
   Attempt admin actions directly
   Verify: Actions blocked
   

3. IDOR Testing

   Login as User A
   Note resource ID
   Try accessing other user's resource by ID
   Verify: Access denied or own data shown
   

Test Patterns

Role Login Pattern

// Using Playwright MCP tools
async function loginAsRole(role, credentials) {
  // Navigate to login
  browser_navigate({ url: "/​login" });

  // Fill login form
  browser_fill_form({
    fields: [
      { name: "Email", type: "textbox", ref: "[email-ref]", value: credentials.email },
      { name: "Password", type: "textbox", ref: "[password-ref]", value: credentials.password }
    ]
  });

  // Submit
  browser_click({ element: "Login button", ref: "[submit-ref]" });

  // Wait for dashboard
  browser_wait_for({ text: "Dashboard" });

  // Verify
  browser_snapshot();
}

Access Verification Pattern

async function verifyAccess(url, shouldHaveAccess) {
  browser_navigate({ url });
  const snapshot = browser_snapshot();

  if (shouldHaveAccess) {
    // Should see page content
    verify(snapshot.contains(expectedContent));
  } else {
    // Should see 403 or redirect
    verify(snapshot.contains("Access Denied") || currentUrl === "/​login");
  }
}

Role Matrix Test Pattern

const roleMatrix = {
  guest: {
    canAccess: ["/", "/​about", "/​login", "/​register"],
    cannotAccess: ["/​dashboard", "/​profile", "/​admin"]
  },
  user: {
    canAccess: ["/", "/​about", "/​dashboard", "/​profile"],
    cannotAccess: ["/​admin", "/​admin/​users"]
  },
  admin: {
    canAccess: ["/", "/​about", "/​dashboard", "/​profile", "/​admin", "/​admin/​users"],
    cannotAccess: []
  }
};

for (const [role, permissions] of Object.entries(roleMatrix)) {
  loginAsRole(role);

  for (const url of permissions.canAccess) {
    verifyAccess(url, true);
  }

  for (const url of permissions.cannotAccess) {
    verifyAccess(url, false);
  }

  logout();
}

Best Practices

1. Test Every Role - Never skip a role
2. Test Both Access and Denial - Verify can AND cannot access
3. Clean Session Between Roles - Logout before testing next role
4. Document Credentials - Keep test credentials in the plan
5. Check Console Errors - Look for JavaScript errors on each page
6. Verify Visual Elements - Use snapshots to verify content
7. Test Edge Cases - Empty states, large data, etc.
