"""
1. Create an HttpRequest object, which is what Django will see when a user's browser asks for a page
2. Pass it to `home_page` view, which gives us a response.
3. Extract `.content` of the response, which are byte value, and should be decoded into string (HTML format)
4. Check HTML starts and end with <html> tag
5. Want to find <title> tag in the middle
1. Instead of manually creating HttpRequest object and calling view function to get response, pass in URL to `self.client.get()` and get response directly
3. `.assertTemplateUsed` is the test method that Django Test Case provides. it checks whether template was used to render a response
