AppTest: test & build interactive Python data apps faster

Hi!
Does the file I want to test need to be at the same folder where I’m running the test file?

For example, let’s say I have the following:
myproject/
├── app.py
└── tests/
└── test_app.py

when I try to run my app.py from test_app.py, it seems to try to access app.py from “tests” directory.

Thanks!
