Phase 0: Prerequisites Check

CRITICAL: Before running any tests, verify all prerequisites.

0.1 Verify MCP Servers Available

# List available MCP tools
MCPSearch query="telegram"
MCPSearch query="gmail"
MCPSearch query="supabase"
MCPSearch query="chrome"

Required servers:

• telegram-mcp

  - For Telegram bot testing

• gmail

  - For OTP/email verification

• supabase

  - For database state verification

• chrome-devtools

  - For portal testing (optional)

0.2 Verify Telegram User Context

The Telegram MCP uses the authenticated user's context. Verify by:

mcp__telegram-mcp__get_me

This returns the user profile associated with the Telegram MCP.

0.3 Identify Bot Chat

Find the chat with the Nikita bot:

mcp__telegram-mcp__list_chats

Look for

@Nikita_my_bot

0.4 Verify Cloud Run Deployment

gcloud run services describe nikita-api --region us-central1 --format='value(status.url)'

Expected:

https://nikita-api-1040094048579.us-central1.run.app

Phase 1: Test Execution

1.1 Telegram Bot Testing

Use when: Testing bot responses, conversation flow, command handling.

# Step 1: Find bot chat
mcp__telegram-mcp__list_chats
# Look for Nikita bot

# Step 2: Send test message
mcp__telegram-mcp__send_message chat_id="<bot_chat_id>" text="Hello, testing"

# Step 3: Wait for response (5-10 seconds for LLM)
sleep 10

# Step 4: Get bot responses
mcp__telegram-mcp__get_messages chat_id="<bot_chat_id>" limit=5

Verify:

• Bot responded within reasonable time
• Response is coherent and on-topic
• No error messages in response

1.2 OTP/Authentication Testing

Use when: Testing registration, login, email verification.

# Step 1: Trigger OTP request (via Telegram /start or portal)

# Step 2: Search for OTP email
mcp__gmail__search_emails query="from:noreply subject:Nikita code" max_results=5

# Step 3: Read latest OTP email
mcp__gmail__read_email id="<email_id>"

# Step 4: Extract OTP code from email body

# Step 5: Verify OTP was used (check Supabase)
mcp__supabase__execute_sql query="SELECT * FROM pending_registrations ORDER BY created_at DESC LIMIT 5"

Verify:

• OTP email received within 60 seconds
• OTP code is 8 digits
• pending_registrations table updated

1.3 Database State Verification

Use when: Verifying data persistence after actions.

-- Check user created
SELECT id, telegram_id, chapter, relationship_score FROM users ORDER BY created_at DESC LIMIT 5;

-- Check conversation logged
SELECT id, user_id, type, created_at FROM conversations ORDER BY created_at DESC LIMIT 5;

-- Check generated_prompts populated
SELECT id, user_id, token_count, generation_time_ms, created_at FROM generated_prompts ORDER BY created_at DESC LIMIT 5;

-- Check engagement state
SELECT * FROM engagement_state ORDER BY updated_at DESC LIMIT 5;

-- Check score history
SELECT * FROM score_history ORDER BY created_at DESC LIMIT 5;

Execute via:

mcp__supabase__execute_sql query="<SQL>"

1.4 Log Analysis

Use when: Checking for errors, verifying request processing.

# Get recent logs
gcloud run services logs read nikita-api --region us-central1 --limit 100 --format='value(textPayload)'

# Filter for errors
gcloud run services logs read nikita-api --region us-central1 --limit 100 | grep -i error

# Check specific request
gcloud run services logs read nikita-api --region us-central1 --limit 100 | grep -i "user_id"

Verify:

• No unhandled exceptions
• No 500 errors
• Request/response times acceptable

1.5 Portal Testing (Optional)

Use when: Testing web portal functionality.

# Step 1: Navigate to portal
mcp__chrome-devtools__navigate_page url="https://your-portal-url.vercel.app"

# Step 2: Take screenshot
mcp__chrome-devtools__take_screenshot

# Step 3: Check for login form
mcp__chrome-devtools__evaluate_script script="document.querySelector('form')?.innerHTML"

# Step 4: Fill and submit form
mcp__chrome-devtools__fill selector="input[name='email']" value="test@example.com"
mcp__chrome-devtools__click selector="button[type='submit']"

Phase 2: Test Report Generation

2.1 Report Template

After completing tests, generate a structured report:

## E2E Test Report - [DATE]

### Scope: [full/telegram/portal/otp/conversation]

### Test Results

| Test | Status | Evidence |
|------|--------|----------|
| Bot response | PASS/FAIL | [response content] |
| Database persistence | PASS/FAIL | [row count] |
| OTP delivery | PASS/FAIL | [email received] |
| Log analysis | PASS/FAIL | [error count] |

### Issues Found

1. **Issue**: [description]
   - **Severity**: P0/P1/P2
   - **Evidence**: [logs/screenshots]
   - **Recommended Action**: [fix/investigate]

### Metrics

- Total test duration: X min
- Bot response time: X ms
- Database query time: X ms
- Errors in logs: X

### Next Actions

- [ ] File issues for failures
- [ ] Update event-stream.md
- [ ] Deploy fixes if critical

2.2 Log to Event Stream

After test completion, update event-stream.md:

[YYYY-MM-DDTHH:MM:SSZ] E2E_TEST: [scope] - [PASS/FAIL] - [summary]

Example:

[2025-12-21T18:30:00Z] E2E_TEST: telegram - PASS - Bot response, DB persistence, no log errors

Phase 3: Failure Handling

3.1 When Tests Fail

1. Capture full error context

   • MCP response bodies
   • Database query results
   • Log excerpts

2. Categorize the failure

   • Infrastructure (Cloud Run, Neo4j, Supabase)
   • Code bug (logic error, missing handler)
   • Configuration (missing env var)
   • External service (Telegram API, OpenAI)

3. Create GitHub issue if not trivial:

   gh issue create --title "E2E: [scope] test failure" \
     --body "## Context\n...\n## Evidence\n...\n## Expected\n..."
   

4. Update event-stream.md:

   [TIMESTAMP] E2E_FAIL: [scope] - [error type] - [brief description]
   

3.2 Common Failure Patterns

Activation Patterns

This skill auto-activates when:

• User says "run E2E tests", "verify implementation", "test the bot"
• After

  /implement

  completes successfully
• User invokes

  /e2e-test

  command
• User asks to "check if it's working in production"

Best Practices

1. Always run

   full

   scope after feature implementations
2. Check logs first when bot isn't responding
3. Verify DB state before assuming data loss
4. Use Telegram MCP user - don't create test fixtures
5. Document all failures in event-stream.md
6. Create issues for non-trivial failures
