+# BotTest Development Prompt Guide
+
+**Version:** 6.1.0  
+**Purpose:** Test infrastructure for General Bots ecosystem
+
+---
+
+## Core Principle
+
+**Reuse botserver bootstrap code** - Don't duplicate installation logic. The bootstrap module already knows how to install PostgreSQL, MinIO, Redis. We wrap it with test-specific configuration (custom ports, temp directories).
+
+---
+
+## Architecture
+
+```
+TestHarness::setup()
+    │
+    ├── Allocate unique ports (15000+)
+    ├── Create ./tmp/bottest-{uuid}/
+    │
+    ├── Start services (via bootstrap)
+    │   ├── PostgreSQL on custom port
+    │   ├── MinIO on custom port  
+    │   └── Redis on custom port
+    │
+    ├── Start mock servers
+    │   ├── MockZitadel (wiremock)
+    │   ├── MockLLM (wiremock)
+    │   └── MockWhatsApp (wiremock)
+    │
+    ├── Run migrations
+    └── Return TestContext
+
+TestContext provides:
+    - db_pool() -> Database connection
+    - minio_client() -> S3 client
+    - redis_client() -> Redis client
+    - mock_*() -> Mock server controls
+
+On Drop:
+    - Stop all services
+    - Remove temp directory
+```
+
+---
+
+## Code Style
+
+Same as botserver PROMPT.md:
+- KISS, NO TALK, SECURED CODE ONLY
+- No comments, no placeholders
+- Complete, production-ready code
+- Return 0 warnings
+
+---
+
+## Test Categories
+
+### Unit Tests (no services)
+```rust
+#[test]
+fn test_pure_logic() {
+    // No TestHarness needed
+    // Test pure functions directly
+}
+```
+
+### Integration Tests (with services)
+```rust
+#[tokio::test]
+async fn test_with_database() {
+    let ctx = TestHarness::quick().await.unwrap();
+    let pool = ctx.db_pool().await.unwrap();
+    // Use real database
+}
+```
+
+### E2E Tests (with browser)
+```rust
+#[tokio::test]
+async fn test_user_flow() {
+    let ctx = TestHarness::full().await.unwrap();
+    let server = ctx.start_botserver().await.unwrap();
+    let browser = Browser::new().await.unwrap();
+    // Automate browser
+}
+```
+
+---
+
+## Mock Server Patterns
+
+### Expect specific calls
+```rust
+ctx.mock_llm().expect_completion("hello", "Hi there!");
+```
+
+### Verify calls were made
+```rust
+ctx.mock_llm().assert_called_times(2);
+```
+
+### Simulate errors
+```rust
+ctx.mock_llm().next_call_fails(500, "Internal error");
+```
+
+---
+
+## Fixture Patterns
+
+### Factory functions
+```rust
+let user = fixtures::admin_user();
+let bot = fixtures::bot_with_kb();
+let session = fixtures::active_session(&user, &bot);
+```
+
+### Insert into database
+```rust
+ctx.insert(&user).await;
+ctx.insert(&bot).await;
+```
+
+---
+
+## Cleanup
+
+Always automatic via Drop trait. But can force:
+```rust
+ctx.cleanup().await;  // Explicit cleanup
+```
+
+---
+
+## Parallel Safety
+
+- Each test gets unique ports via PortAllocator
+- Each test gets unique temp directory
+- No shared state between tests
+- Safe to run with `cargo test -j 8`

+# BotTest - Comprehensive Test Infrastructure
+
+**Version:** 6.1.0  
+**Status:** Production-ready test framework  
+**Architecture:** Isolated ephemeral environments with real services
+
+---
+
+## Overview
+
+BotTest provides enterprise-grade testing infrastructure for the General Bots ecosystem. Each test run creates a completely isolated environment with real PostgreSQL, MinIO, and Redis instances on dynamic ports, ensuring zero state pollution between tests and enabling full parallel execution.

+
+## Core Components
+
+### Test Harness
+
+Orchestrates complete test lifecycle with automatic cleanup:
+
+```rust
+pub struct TestHarness {
+    pub id: Uuid,
+    pub root_dir: PathBuf,
+    pub postgres: PostgresService,
+    pub minio: MinioService,
+    pub redis: RedisService,
+    pub mocks: MockRegistry,
+}
+
+impl TestHarness {
+    pub async fn new(config: TestConfig) -> Result<Self>;
+    pub async fn with_botserver(&self) -> Result<BotServerProcess>;
+    pub fn connection_string(&self) -> String;
+    pub fn s3_endpoint(&self) -> String;
+}
+
+impl Drop for TestHarness {
+    fn drop(&mut self) {
+        // Graceful shutdown + cleanup ./tmp/bottest-{uuid}/
+    }
+}
+```
+
+### Service Management
+
+Real services via botserver bootstrap (no Docker dependency):
+
+```rust
+impl PostgresService {
+    pub async fn start(port: u16, data_dir: &Path) -> Result<Self>;
+    pub async fn run_migrations(&self) -> Result<()>;
+    pub async fn create_database(&self, name: &str) -> Result<()>;
+    pub async fn execute(&self, sql: &str) -> Result<()>;
+    pub fn connection_string(&self) -> String;
+}
+
+impl MinioService {
+    pub async fn start(api_port: u16, console_port: u16, data_dir: &Path) -> Result<Self>;
+    pub async fn create_bucket(&self, name: &str) -> Result<()>;
+    pub fn endpoint(&self) -> String;
+    pub fn credentials(&self) -> (String, String);
+}
+
+impl RedisService {
+    pub async fn start(port: u16, data_dir: &Path) -> Result<Self>;
+    pub fn connection_string(&self) -> String;
+}
+```
+
+### Mock Servers
+
+Flexible expectation-based mocking:
+
+```rust
+impl MockLLM {
+    pub async fn start(port: u16) -> Result<Self>;
+    pub fn expect_completion(&mut self, prompt_contains: &str, response: &str) -> &mut Self;
+    pub fn expect_streaming(&mut self, chunks: Vec<&str>) -> &mut Self;
+    pub fn expect_embedding(&mut self, dimensions: usize) -> &mut Self;
+    pub fn with_latency(&mut self, ms: u64) -> &mut Self;
+    pub fn with_error_rate(&mut self, rate: f32) -> &mut Self;
+    pub fn verify(&self) -> Result<()>;
+}
+
+impl MockWhatsApp {
+    pub async fn start(port: u16) -> Result<Self>;
+    pub fn expect_send_message(&mut self, to: &str) -> MessageExpectation;
+    pub fn expect_send_template(&mut self, name: &str) -> TemplateExpectation;
+    pub fn simulate_incoming(&self, from: &str, text: &str) -> Result<()>;
+    pub fn simulate_webhook(&self, event: WebhookEvent) -> Result<()>;
+}
+
+impl MockZitadel {
+    pub async fn start(port: u16) -> Result<Self>;
+    pub fn expect_login(&mut self, user: &str, password: &str) -> TokenResponse;
+    pub fn expect_token_refresh(&mut self) -> &mut Self;
+    pub fn expect_introspect(&mut self, token: &str, active: bool) -> &mut Self;
+    pub fn create_test_user(&mut self, email: &str) -> User;
+}
+```
+

+
+## Test Categories
+
+### Unit Tests
+
+Fast, isolated, no external services:
+
+```rust
+#[test]
+fn test_basic_parser() {
+    let ast = parse("TALK \"Hello\"").unwrap();
+    assert_eq!(ast.statements.len(), 1);
+}
+
+#[test]
+fn test_config_csv_parsing() {
+    let config = ConfigManager::from_str("name,value\nllm-model,test.gguf");
+    assert_eq!(config.get("llm-model"), Some("test.gguf"));
+}
+```
+
+### Integration Tests
+
+Real services, isolated environment:
+
+```rust
+#[tokio::test]
+async fn test_database_operations() {
+    let harness = TestHarness::new(TestConfig::default()).await.unwrap();
+    
+    harness.postgres.execute("INSERT INTO users (email) VALUES ('test@example.com')").await.unwrap();
+    
+    let result = harness.postgres.query_one("SELECT email FROM users").await.unwrap();
+    assert_eq!(result.get::<_, String>("email"), "test@example.com");
+}
+
+#[tokio::test]
+async fn test_file_storage() {

+    
+    harness.minio.create_bucket("test-bucket").await.unwrap();
+    harness.minio.put_object("test-bucket", "file.txt", b"content").await.unwrap();
+    
+    let data = harness.minio.get_object("test-bucket", "file.txt").await.unwrap();
+    assert_eq!(data, b"content");
+}
+```
+
+### Bot Conversation Tests
+
+Simulate full conversation flows:
+
+```rust
+#[tokio::test]
+async fn test_greeting_flow() {
+    let harness = TestHarness::new(TestConfig::with_llm_mock()).await.unwrap();
+    
+    harness.mocks.llm.expect_completion("greeting", "Hello! How can I help?");
+    
+    let mut conv = ConversationTest::new(&harness, "test-bot").await.unwrap();
+    
+    conv.user_says("Hi").await;
+    conv.assert_response_contains("Hello").await;
+    conv.assert_response_contains("help").await;
+}
+
+#[tokio::test]
+async fn test_knowledge_base_search() {
+    let harness = TestHarness::new(TestConfig::with_kb()).await.unwrap();
+    
+    harness.seed_kb("products", vec![
+        ("SKU-001", "Widget Pro - Premium quality widget"),
+        ("SKU-002", "Widget Basic - Entry level widget"),
+    ]).await.unwrap();
+    
+    let mut conv = ConversationTest::new(&harness, "kb-bot").await.unwrap();
+    
+    conv.user_says("Tell me about Widget Pro").await;
+    conv.assert_response_contains("Premium quality").await;
+}
+
+#[tokio::test]
+async fn test_human_handoff() {
+    let harness = TestHarness::new(TestConfig::default()).await.unwrap();
+    
+    let mut conv = ConversationTest::new(&harness, "support-bot").await.unwrap();
+    
+    conv.user_says("I want to speak to a human").await;
+    conv.assert_transferred_to_human().await;
+    conv.assert_queue_position(1).await;
+}
+```
+
+### Attendance Module Tests
+
+Multi-user concurrent scenarios:
+
+```rust
+#[tokio::test]
+async fn test_queue_ordering() {
+    let harness = TestHarness::new(TestConfig::default()).await.unwrap();
+    
+    let customer1 = harness.create_customer("customer1@test.com").await;
+    let customer2 = harness.create_customer("customer2@test.com").await;
+    let attendant = harness.create_attendant("agent@test.com").await;
+    
+    harness.enter_queue(&customer1, Priority::Normal).await;
+    harness.enter_queue(&customer2, Priority::High).await;
+    
+    let next = harness.get_next_in_queue(&attendant).await.unwrap();
+    assert_eq!(next.customer_id, customer2.id); // High priority first
+}
+
+#[tokio::test]
+async fn test_concurrent_assignment() {
+    let harness = TestHarness::new(TestConfig::default()).await.unwrap();
+    
+    let customers: Vec<_> = (0..10).map(|i| 
+        harness.create_customer(&format!("c{}@test.com", i))
+    ).collect();
+    
+    let attendants: Vec<_> = (0..3).map(|i|
+        harness.create_attendant(&format!("a{}@test.com", i))
+    ).collect();
+    
+    // Concurrent assignment - no race conditions
+    let assignments = join_all(customers.iter().map(|c| 
+        harness.auto_assign(c)
+    )).await;
+    
+    // Verify no double-assignments
+    let assigned_attendants: HashSet<_> = assignments.iter()
+        .filter_map(|a| a.as_ref().ok())
+        .map(|a| a.attendant_id)
+        .collect();
+    
+    assert!(assignments.iter().all(|a| a.is_ok()));
+}
+```
+
+### E2E Browser Tests
+
+Full stack with real browser:
+
+```rust
+#[tokio::test]
+async fn test_chat_interface() {
+    let harness = TestHarness::new(TestConfig::full_stack()).await.unwrap();
+    let server = harness.with_botserver().await.unwrap();

+    let response = page.text(".bot-message").await.unwrap();
+    
+    assert!(response.contains("Hello"));
+}
+
+#[tokio::test]
+async fn test_attendant_dashboard() {
+    let harness = TestHarness::new(TestConfig::full_stack()).await.unwrap();
+    let server = harness.with_botserver().await.unwrap();
+    
+    let browser = Browser::new_headless().await.unwrap();
+    let page = browser.new_page().await.unwrap();
