-# Onboarding Router Test Cases
-
-## Dashboard Access for Completed Users
-
-### Test Case 1: Training Completed
-**Given**: User has completed training (`current_step: "training_completed"`)
-**When**: User logs in
-**Expected**: `nextAction: "dashboard"`
-**Message**: "Great! Your AI model is ready. Welcome to your dashboard!"
-
-### Test Case 2: Dashboard Accessible
-**Given**: User has reached dashboard accessible step (`current_step: "dashboard_accessible"`)  
-**When**: User logs in
-**Expected**: `nextAction: "dashboard"`
-**Message**: "Welcome back! You're ready to use your AI-powered dashboard."
-
-### Test Case 3: High Completion Percentage
-**Given**: User has `completion_percentage >= 80` but step may not be final
-**When**: User logs in
-**Expected**: `nextAction: "dashboard"`
-
-### Test Case 4: Fully Completed
-**Given**: User has `fully_completed: true`
-**When**: User logs in
-**Expected**: `nextAction: "dashboard"`
-
-### Test Case 5: In Progress User
-**Given**: User has `current_step: "sales_data_uploaded"` 
-**When**: User logs in
-**Expected**: `nextAction: "onboarding_data"`
-**Should**: Continue onboarding flow
-
-## Manual Testing
-
-1. Complete onboarding flow for a user
-2. Log out 
-3. Log back in
-4. Verify user goes directly to dashboard (not onboarding)
-5. Check welcome message shows completion status
