I am trying to develop a new feature for Airflow and want to use Breeze for testing. I made changes to a file in my local repository (tests/sensors/test_filesystem.py) but when I open Breeze and check the file, I can't see my modifications.

Question: How can I make Breeze load my local code changes so I can properly test my modifications?

Here's what I did so far:

1. Cloned the Airflow repository and modified tests/sensors/test_filesystem.py in my local environment to include the following test:

# test_filesystem.py (local repository)
# (...)
    def test_task_defer(self):
        # (...)

        assert isinstance(exc.value.trigger, FileTrigger), "Trigger is not a FileTrigger"

   def test_poke_for_modification_file_not_modified(self):
        # my test code

3. Ran breeze shell to start the Breeze container.
4. Inside Breeze, I checked the file using:

cat tests/sensors/test_filesystem.py

But my changes were not present:

# test_filesystem.py (breeze shell)
# (...)     
    def test_task_defer(self):         
        # (...) 
         
        assert isinstance(exc.value.trigger, FileTrigger), "Trigger is not a FileTrigger"

4. I tried restarting Breeze:

breeze stop
breeze shell

but still no effect.
