# Tier 3 E2E Tests Implementation - Session Summary

**Date**: 2026-01-27  
**Status**: 🔄 IN PROGRESS (6/21 scenarios completed)  
**Achievement**: High-priority Tier 3 tests implemented (security, HTTP runner, RBAC)

---

## Overview

Started implementation of **Tier 3 End-to-End Tests** for the Attune automation platform. Tier 3 focuses on advanced features, edge cases, security validation, and operational scenarios. Successfully implemented **6 high-priority scenarios** with **15 comprehensive test functions** (~2,800 lines of code).

---

## Work Completed

### 1. Test Files Implemented ✅

#### T3.20: Secret Injection Security (HIGH Priority) 🔐
**File**: `tests/e2e/tier3/test_t3_20_secret_injection.py` (566 lines)

**4 comprehensive security tests:**
1. `test_secret_injection_via_stdin` - Validates secrets passed via stdin (NOT env vars)
2. `test_secret_encryption_at_rest` - Verifies encryption flag configuration
3. `test_secret_not_in_execution_logs` - Tests secret redaction in output
4. `test_secret_access_tenant_isolation` - Validates cross-tenant isolation

**Key Security Validations:**
- ✅ Secrets passed via stdin (secure channel)
- ✅ Secrets NOT in environment variables (/proc/pid/environ)
- ✅ Secrets NOT exposed in execution logs
- ✅ Encryption at rest configured correctly
- ✅ Tenant isolation enforced (users cannot access other tenants' secrets)
- ✅ Security best practices documented

**Why This Matters:**
Environment variables can be inspected via `/proc/{pid}/environ`, making them insecure for secrets. Passing secrets via stdin prevents exposure to other processes and is a security best practice.

---

#### T3.10: RBAC Permission Checks (MEDIUM Priority) 🔒
**File**: `tests/e2e/tier3/test_t3_10_rbac.py` (524 lines)

**4 role-based access tests:**
1. `test_viewer_role_permissions` - Viewer role (read-only access)
2. `test_admin_role_permissions` - Admin role (full CRUD access)
3. `test_executor_role_permissions` - Executor role (execute + read only)
4. `test_role_permissions_summary` - Documents permission matrix

**RBAC Validation:**
- ✅ Viewer: GET only, blocked from CREATE/DELETE (403 Forbidden)
- ✅ Admin: Full CRUD access to all resources
- ✅ Executor: Can execute actions and read resources, cannot create
- ✅ Clear error messages for permission denials
- ✅ Permission matrix documented as reference

**Role Definitions:**
- **admin** - Full access (create, read, update, delete, execute)
- **editor** - Create/update resources, execute actions
- **executor** - Execute actions and read resources only
- **viewer** - Read-only access to resources

---

#### T3.18: HTTP Runner Execution (MEDIUM Priority) 🌐
**File**: `tests/e2e/tier3/test_t3_18_http_runner.py` (473 lines)

**4 HTTP runner tests:**
1. `test_http_runner_basic_get` - GET request with headers
2. `test_http_runner_post_with_json` - POST request with JSON body
3. `test_http_runner_authentication_header` - Bearer token authentication
4. `test_http_runner_error_handling` - 4xx/5xx error handling

**HTTP Runner Features Validated:**
- ✅ GET and POST HTTP methods
- ✅ Custom headers injection
- ✅ JSON body serialization
- ✅ Authentication via Bearer tokens (from secrets)
- ✅ Response capture (status code, headers, body)
- ✅ Error status codes (404, 500) handled gracefully
- ✅ Integration with external APIs (tested with httpbin.org)

**Use Cases:**
- Making REST API calls from automations
- Webhook notifications
- External service integration
- API-based workflows

---

#### T3.13: Invalid Action Parameters (MEDIUM Priority) ⚠️
**File**: `tests/e2e/tier3/test_t3_13_invalid_parameters.py` (559 lines)

**4 parameter validation tests:**
1. `test_missing_required_parameter` - Required param validation
2. `test_invalid_parameter_type` - Type checking behavior
3. `test_extra_parameters_ignored` - Extra params handled gracefully
4. `test_parameter_default_values` - Default values applied correctly

**Parameter Validation:**
- ✅ Missing required parameters fail immediately with clear errors
- ✅ Validation happens before worker scheduling (resource efficiency)
- ✅ Type validation behavior documented
- ✅ Default values applied when params not provided
- ✅ Extra/unexpected parameters don't cause failures
- ✅ Clear error messages guide users

**Benefits:**
- Early parameter validation prevents wasted worker resources
- Clear error messages improve developer experience
- Default values reduce boilerplate in rule configurations

---

#### T3.1: Date Timer with Past Date (LOW Priority) ⏱️
**File**: `tests/e2e/tier3/test_t3_01_past_date_timer.py` (305 lines)

**3 edge case tests:**
1. `test_past_date_timer_immediate_execution` - 1 hour past
2. `test_just_missed_date_timer` - 2 seconds past
3. `test_far_past_date_timer` - 1 year past

**Edge Case Coverage:**
- ✅ Past date timer behavior documented (execute immediately or reject)
- ✅ Boundary conditions tested (recently passed dates)
- ✅ Far past validation (1 year ago)
- ✅ Clear error messages when dates rejected
- ✅ No silent failures

**Expected Behaviors:**
- Immediate execution OR rejection with clear error
- Consistent behavior across all past date scenarios
- Proper timer expiration handling

---

#### T3.4: Webhook with Multiple Rules (LOW Priority) 🔗
**File**: `tests/e2e/tier3/test_t3_04_webhook_multiple_rules.py` (343 lines)

**2 multi-rule tests:**
1. `test_webhook_fires_multiple_rules` - 1 webhook → 3 rules
2. `test_webhook_multiple_posts_multiple_rules` - 3 posts × 2 rules

**Multi-Rule Validation:**
- ✅ Single webhook event triggers multiple rules simultaneously
- ✅ Multiple enforcements created from one event
- ✅ Independent rule execution
- ✅ Correct execution count: webhooks × rules
- ✅ All rules see same event payload
- ✅ No duplicate events

**Use Cases:**
- Fan-out automation (one trigger → many actions)
- Multi-team notifications
- Parallel processing workflows

---
