How do I document my automated tests using C4 model and StructurizR

Question

I use Web Application Factory for automated testing. It's essential to show that on the component level, there has to be a DAL layer that provides an extension point so that I can use two different data configurations:

1. the real one
2. an in-memory db or a docker-container instance for web-application-factory-based tests

Should I use two deployment diagrams to show this? I am not sure if the deployment diagram is appropriate because the test stage is executed before the deployment.

Another option would be something like

softwareSystem {
  db = container "Real DB"
  testDb = container "In-memory/Docker DB"
  api = container "API"
  api -> db "reads/writes data"
  api -> testDb "reads/writes data during tests"
}
