+## Integration Test Writing Guide
+
+### Test Patterns and Best Practices
+
+#### 1. Test File Naming Convention
+- Use descriptive names: `test_{category}_{feature}.py`
+- Common categories: `host_mode`, `api`, `scheduler`, `light`, `areas_and_devices`
+- Examples:
+  - `test_host_mode_basic.py` - Basic host mode functionality
+  - `test_api_message_batching.py` - API message batching
+  - `test_scheduler_stress.py` - Scheduler stress testing
+
+#### 2. Essential Imports
+```python
+from __future__ import annotations
+
+import asyncio
+from typing import Any
+
+import pytest
+from aioesphomeapi import EntityState, SensorState
+
+from .types import APIClientConnectedFactory, RunCompiledFunction
+```
+
+#### 3. Common Test Patterns
+
+##### Basic Entity Test
+```python
+@pytest.mark.asyncio
+async def test_my_sensor(
+    yaml_config: str,
+    run_compiled: RunCompiledFunction,
+    api_client_connected: APIClientConnectedFactory,
+) -> None:
+    """Test sensor functionality."""
+    async with run_compiled(yaml_config), api_client_connected() as client:
+        # Get entity list
+        entities, services = await client.list_entities_services()
+
+        # Find specific entity
+        sensor = next((e for e in entities if e.object_id == "my_sensor"), None)
+        assert sensor is not None
+```
+
+##### State Subscription Pattern
+```python
+# Track state changes with futures
+loop = asyncio.get_running_loop()
+states: dict[int, EntityState] = {}
+state_future: asyncio.Future[EntityState] = loop.create_future()
+
+def on_state(state: EntityState) -> None:
+    states[state.key] = state
+    # Check for specific condition using isinstance
+    if isinstance(state, SensorState) and state.state == expected_value:
+        if not state_future.done():
+            state_future.set_result(state)
+
+client.subscribe_states(on_state)
+
+# Wait for state with timeout
+try:
+    result = await asyncio.wait_for(state_future, timeout=5.0)
+except asyncio.TimeoutError:
+    pytest.fail(f"Expected state not received. Got: {list(states.values())}")
+```
+
+##### Service Execution Pattern
+```python
+# Find and execute service
+entities, services = await client.list_entities_services()
+my_service = next((s for s in services if s.name == "my_service"), None)
+assert my_service is not None
+
+# Execute with parameters
+client.execute_service(my_service, {"param1": "value1", "param2": 42})
+```
+
+##### Multiple Entity Tracking
+```python
+# For tests with many entities
+loop = asyncio.get_running_loop()
+entity_count = 50
+received_states: set[int] = set()
+all_states_future: asyncio.Future[bool] = loop.create_future()
+
+def on_state(state: EntityState) -> None:
+    received_states.add(state.key)
+    if len(received_states) >= entity_count and not all_states_future.done():
+        all_states_future.set_result(True)
+
+client.subscribe_states(on_state)
+await asyncio.wait_for(all_states_future, timeout=10.0)
+```
+
+#### 4. YAML Fixture Guidelines
+
+##### Naming Convention
+- Match test function name: `test_my_feature` → `fixtures/my_feature.yaml`
+- Note: Remove `test_` prefix for fixture filename
+
+##### Basic Structure
+```yaml
+esphome:
+  name: test-name  # Use kebab-case
+  # Optional: areas, devices, platformio_options
+
+host:  # Always use host platform for integration tests
+api:   # Port injected automatically
+logger:
+  level: DEBUG  # Optional: Set log level
+
+# Component configurations
+sensor:
+  - platform: template
+    name: "My Sensor"
+    id: my_sensor
+    lambda: return 42.0;
+    update_interval: 0.1s  # Fast updates for testing
+```
+
+##### Advanced Features
+```yaml
+# External components for custom test code
+external_components:
+  - source:
+      type: local
+      path: EXTERNAL_COMPONENT_PATH  # Replaced by test framework
+    components: [my_test_component]
+
+# Areas and devices
+esphome:
+  name: test-device
+  areas:
+    - id: living_room
+      name: "Living Room"
+    - id: kitchen
+      name: "Kitchen"
+      parent_id: living_room
+  devices:
+    - id: my_device
+      name: "Test Device"
+      area_id: living_room
+
+# API services
+api:
+  services:
+    - service: test_service
+      variables:
+        my_param: string
+      then:
+        - logger.log:
+            format: "Service called with: %s"
+            args: [my_param.c_str()]
+```
+
+#### 5. Testing Complex Scenarios
+
+##### External Components
+Create C++ components in `fixtures/external_components/` for:
+- Stress testing
+- Custom entity behaviors
+- Scheduler testing
+- Memory management tests
+
+##### Log Line Monitoring
+```python
+log_lines: list[str] = []
+
+def on_log_line(line: str) -> None:
+    log_lines.append(line)
+    if "expected message" in line:
+        # Handle specific log messages
+
+async with run_compiled(yaml_config, line_callback=on_log_line):
+    # Test implementation
+```
+
+Example using futures for specific log patterns:
+```python
+import re
+
+loop = asyncio.get_running_loop()
+connected_future = loop.create_future()
+service_future = loop.create_future()
+
+# Patterns to match
+connected_pattern = re.compile(r"Client .* connected from")
+service_pattern = re.compile(r"Service called")
+
+def check_output(line: str) -> None:
+    """Check log output for expected messages."""
+    if not connected_future.done() and connected_pattern.search(line):
+        connected_future.set_result(True)
+    elif not service_future.done() and service_pattern.search(line):
+        service_future.set_result(True)
+
+async with run_compiled(yaml_config, line_callback=check_output):
+    async with api_client_connected() as client:
+        # Wait for specific log message
+        await asyncio.wait_for(connected_future, timeout=5.0)
+
+        # Do test actions...
+
+        # Wait for service log
+        await asyncio.wait_for(service_future, timeout=5.0)
+```
+
+**Note**: Tests that monitor log messages typically have fewer race conditions compared to state-based testing, making them more reliable. However, be aware that the host platform currently does not have a thread-safe logger, so logging from threads will not work correctly.
+
+##### Timeout Handling
+```python
+# Always use timeouts for async operations
+try:
+    result = await asyncio.wait_for(some_future, timeout=5.0)
+except asyncio.TimeoutError:
+    pytest.fail("Operation timed out - check test expectations")
+```
+
+#### 6. Common Assertions
+
+```python
+# Device info
+assert device_info.name == "expected-name"
+assert device_info.compilation_time is not None
+
+# Entity properties
+assert sensor.accuracy_decimals == 2
+assert sensor.state_class == 1  # measurement
+assert sensor.force_update is True
+
+# Service availability
+assert len(services) > 0
+assert any(s.name == "expected_service" for s in services)
+
+# State values
+assert state.state == expected_value
+assert state.missing_state is False
+```
+
+#### 7. Debugging Tips
+
+- Use `pytest -s` to see ESPHome output during tests
+- Add descriptive failure messages to assertions
+- Use `pytest.fail()` with detailed error info for timeouts
+- Check `log_lines` for compilation or runtime errors
+- Enable debug logging in YAML fixtures when needed
+
+#### 8. Performance Considerations
+
+- Use short update intervals (0.1s) for faster tests
+- Set reasonable timeouts (5-10s for most operations)
+- Batch multiple assertions when possible
+- Clean up resources properly using context managers
+
+#### 9. Test Categories
+
+- **Basic Tests**: Minimal functionality verification
+- **Entity Tests**: Sensor, switch, light behavior
+- **API Tests**: Message batching, services, events
+- **Scheduler Tests**: Timing, defer operations, stress
+- **Memory Tests**: Conditional compilation, optimization
+- **Integration Tests**: Areas, devices, complex interactions
