Low coverage generating tests on a ROS Node

[banzo]

We are trying to generate tests for our ROS project. Running Pynguin on a simple vehicle class shows a coverage of 0.187500 and the test generated is not very useful:

# Test cases automatically generated by Pynguin (https://www.pynguin.eu).
# Please check them before you use them.
import pytest
import vehicle as module_0


@pytest.mark.xfail(strict=True)
def test_case_0():
    module_0.Vehicle()

We are guessing that Pynguin gets lost at one point, and are looking for some insight on what we can do.

To Reproduce
We made a minimal example here.

Expected behavior
We would expect the coverage to be a bit higher, with some relevant tests (test on the speed_profile or even the quickstart example).

Software Version (please complete the following information):

• OS: Docker Ubuntu 22.04 + ROS Humble
• Python version: 3.10.12
• Pynguin Version: 0.34.0
