To create a custom SQL query in Django, you can use the `raw()` method of a model's manager. Here’s an example:

```python
from your_app.models import YourModel

# Custom SQL query
query = "SELECT * FROM your_app_yourmodel WHERE some_field = %s"
results = YourModel.objects.raw(query, [value])
```

You can also use the `connection` object for executing raw SQL:

```python
from django.db import connection

with connection.cursor() as cursor:
cursor.execute("SELECT * FROM your_app_yourmodel WHERE some_field = %s", [value])
results = cursor.fetchall()
```

I test my Django application using a combination of unit tests, integration tests, and functional tests. I utilize Django's built-in testing framework, which allows me to write test cases for models, views, and forms.

Django supports several caching strategies, including:

1. **In-Memory Caching**: Uses local memory to store cache data (e.g., `Memcached` or `Redis`).
2. **File-Based Caching**: Stores cache data in files on the filesystem.
3. **Database Caching**: Uses the database to store cache data.
4. **View Caching**: Caches the output of entire views using the `@cache_page` decorator.
5. **Template Fragment Caching**: Caches specific parts of templates using the `{% cache %}` template tag.
6. **Low-Level Caching API**: Provides functions like `cache.set()`, `cache.get()`, and `cache.delete()` for custom caching logic.

These strategies can be combined and configured based on application needs.
