🔧 Test Field-Specific Error Handling

This page tests the field-specific error handling implementation for the registration form.

🎯 What Should Happen Now

Before Fix: Generic "Registration failed. Please try again." banner at the top

❌ Registration failed. Please try again.

After Fix: Specific field errors below each problematic field

✅ Username: "This username is already taken. Please choose another." (below username field)
✅ Email: "This email is already registered. Please use a different email." (below email field)
✅ Phone: "This phone number is already registered. Please use a different phone number." (below phone field)

🧪 Test Cases to Try

Test 1: Duplicate Username

Try registering with an existing username (e.g., "admin", "test", "user")

Expected: Red error message below username field: "This username is already taken. Please choose another."

No generic banner should appear at the top

Test 2: Duplicate Email

Try registering with an existing email address

Expected: Red error message below email field: "This email is already registered. Please use a different email."

No generic banner should appear at the top

Test 3: Duplicate Phone Number

Try registering with an existing phone number

Expected: Red error message below phone field: "This phone number is already registered. Please use a different phone number."

No generic banner should appear at the top

Test 4: Multiple Field Errors

Try registering with multiple invalid fields (e.g., invalid email + weak password)

Expected: Multiple red error messages below respective fields

No generic banner should appear at the top

Test 5: Validation Errors

Try submitting with empty fields or invalid formats

Expected: Specific error messages below each invalid field

No generic banner should appear at the top

🚀 How to Test

  1. Start the servers:
    python app.py (Backend on port 7060)
    python run_frontend.py (Frontend on port 8000)
  2. Open registration form: https://prodevroger-ishingiro.hf.space/register
  3. Open browser developer tools: Press F12 to see console logs
  4. Try the test cases above
  5. Verify:
    • No generic "Registration failed" banner appears at the top
    • Specific error messages appear below each problematic field
    • Red borders appear around fields with errors
    • Console shows detailed error parsing logs

🔍 Debug Information

Open browser developer tools (F12) and check the console for these logs:

✅ Success Criteria

✅ SUCCESS: Each field shows its specific error message below the field with red border. No generic error banner appears at the top of the form.
❌ FAILURE: Generic "Registration failed. Please try again." banner appears at the top of the form.

🛠️ Technical Implementation

Backend Changes (app.py)

Frontend Changes (register.js)

Error Flow

  1. User submits form with errors
  2. Backend validates and returns {"errors": {"field": "message"}}
  3. Frontend parses error response
  4. Frontend clears any generic error messages
  5. Frontend shows specific error below each field
  6. No generic banner appears at the top
