When testing a reflex web app, is there a way to select a file if the rx.upload() component is used to select files to upload?

[aden-collector]

I've been able to write pytest python code to test a reflex web app. I use the AppHarness module and am able to locate elements on a reflex web page and manipulate them (click object, etc.). I am trying to test uploading of files on the app. The app uses the rx.upload() component to select the files to upload. I am unable to use a web component identifier (xpath, etc.) to select a file. Are there any workarounds to select a file for testing like triggering an event or running a javas script function?

Check out how we do it in integration/test_upload.py

reflex/integration/test_upload.py

Lines 180 to 182 in 99d5910

	upload_box = driver.find_elements(By.XPATH, "//input[@type='file']")[
	1 if secondary else 0
	]

upload_box.send_keys(str(target_file))
