LiveServerTestCase
The LiveServerTestCase and ChannelsLiveServerTestCase classes provide additional wrapper functionality for writing tests that directly check a browser window instance, such as when using Selenium.
These classes can be very helpful in testing logic that requires live browser manipulation, such as any logic that uses JavaScript to function.
Note
While testing with live browser instances can definitely be useful, it also tends to provide more overhead.
When possible, consider testing via IntegrationTestCase class instead, as it is designed to test most request/response logic in a more lightweight, performance-friendly manner.
