nicegui.testing with User does not support upload file simution

[youcefpy]

Hello i am new on nicegui, i create a simple app where i need to upload the files and store this files on ftp server. I start to make some tests with nicegui.testing.User (i use this package because i don't need to install the selisium package) i want to know how to simulate a test of uploading files

# simple function for handle_uplaod 
 # file_handler.py 
def handle_file_upload(file_name : str ) : 
    # some logic for store the file on the ftp server 

# main.py
# imports  ... 


ui.page("/")
def main(): 
    ui.upload(on_upload = lambda file_name :handle_file_upload(file_name), auto_upload = True)


ui.run() 

how can i simulate a test for uplaoding files ?

Hi @youcefpy,

Here is an example for simulating ui.upload: https://nicegui.io/documentation/user#complex_elements

async def receive_file(e: events.UploadEventArguments):
    content = await e.file.text()
    reader = csv.DictReader(content.splitlines())
    ui.table(
        columns=[{
            'name': h,
            'label': h.capitalize(),
            'field': h,
        } for h in reader.fieldnames or []],
        rows=list(reader),
    )

ui.upload(on_upload=receive_file)

from nicegui import ui

upload = user.find(ui.upload).elements.pop()
await upload.handle_uploads([
    ui.upload.SmallFileUpload('data.csv', 'text/csv', b'name,age\nAlice,30\nBob,28')
])
await user.should_see(ui.table)
table = user.find(ui.table).elements.pop()
assert table.columns == [
    {'name': 'name', 'label': 'Name', 'field': 'name'},
    {'name': 'age', 'label': 'Age', 'field': 'age'},
]
assert table.rows == [
    {'name': 'Alice', 'age': '30'},
    {'name': 'Bob', 'age': '28'},
]
