Pytest Defaulting to local build directory, even when set otherwise

[sethkaz]

I'm using Pytest to manage the manufacturing tests for an ESP32S3 product I'm working on. I'm finding that something in the software stack is ignoring the app_path parameter when there is a build directory within the same pytest directory.

Project directory structure

Code: Select all

Project root directory
- (main)
- - source code
- (build)
- - main code build files
- (test_app_system_level)
- - (main)
- - - secondary processor source code
- - (build)
- - - secondary processor build files
- - test_app.py

Here's an example test with it's parameters:

Code: Select all

PARAMS = "count, app_path, port"
PARAMS_VALUES = [
    (
        1,
        f"{os.path.dirname(os.path.dirname(__file__))}",
        "/dev/ttyACM0",
    ),
]

@pytest.mark.parametrize(
    PARAMS,
    PARAMS_VALUES,
    indirect=True,
)
def test_hello_world(dut: IdfDut):
    res = dut.expect(r"Hello (\w+)")

    logging.info(f'Hello from {res.group(1).decode("utf-8")}')

I'm running the pytest command from the project root/test_app_system_level/ directory, and for some reason, instead of using the f"{os.path.dirname(os.path.dirname(__file__))}", it just looks in ./build.

I'm seeing this because it gives a wrong chip error, and that error gets cleared up when I delete the project root/test_app_system_level/build directory.

Is there a way to force it to use the directory I'm selecting in app_path?
