lv-ui-testing 2.4.0

A LabVIEW User Interface Testing framework.

LabVIEW User Interface testing

The aim of that package is to create LabVIEW User Interface testing through scripts through pyTest.

Requirements

This package allows python to communicate with the LabVIEW package "ui-testing". You need to have that package installed within your LabVIEW IDE and have the main.vi put in your top VI.

Documentation

Examples can be found on the wiki of the project.

The following example will set a value to control labelled "myNumber", the boolean indicator "greater" should be TRUE when myNumber is > 5.

NOTE: Even tough it's recommended to start the VI first, it should also work as the python script is waiting to connect to it.

# Start the VI "example 2 - value" first then run that script
from lv_ui_testing import ui_testing
import pytest

def test_front_most_vi():
    # Ask the tester daemon what is the front most VI
    front_most_vi = ui_testing.FMV_get_vi_name()
    assert front_most_vi == "example 2 - value.vi"

@pytest.mark.parametrize("number, expected_bool", [ (x, x > 5) for x in range(1, 11)])

def test_set_value(number,expected_bool):
    # Set value to 0
    ui_testing.FMV_set_value_DBL("myNumber", number)
    data_number = ui_testing.FMV_get_value_DBL("myNumber")
    data_bool = ui_testing.FMV_get_value_bool("greater")

    assert data_bool == expected_bool
    assert data_number == number

Run the following command in your command line:

python -m pytest example2.py

You should see the following test happening:
