Launch arguments

HardPy launches pytest tests. User can add own arguments and options for test execution. For example, user can write own script for HardPy to run with special arguments, such as device serial number, and use it in tests.

how to start

1. Launch hardpy init launch_arg.
2. Launch CouchDH instance.
3. Modify the files described below.
4. Launch hardpy run launch_arg.

So that you can run HardPy in separate scripts that use the arguments, you can use pytest's built-in addoption method. You can read more about it here.

conftest.py

def pytest_addoption(parser):
    parser.addoption("--my-opt", action="store", help="add my opt")

@pytest.fixture(scope="session")
def my_opt(request):
    return request.config.getoption("--my-opt")

test_1.py

def test_custom_option_1(request):
    custom_value = request.config.getoption("--my-opt")
    print(f"Custom option value: {custom_value}")
    assert custom_value == "hello"

def test_custom_option_2(my_opt):
    print(f"Custom option value: {my_opt}")
    assert my_opt == "hello"

launch test with your parameter

You can launch tests with this command:

pytest --my-opt hello

Alternatively, you can add the parameter --my-opt hello to the pytest.ini file.
