UserWarning: Unknown distribution option: 'tests_require' #101

• ROS Version: Humble

• OS Version: Ubuntu22.04

• Python Version: 3.10.12

• setuptools Version: 75.2.0

Hello, when I build this project from source, some warnings occurred.

Hers is the output of the command colcon build:

Starting >>> launch_system_modes
/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'
  warnings.warn(msg)                           
--- stderr: launch_system_modes

/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'
  warnings.warn(msg)
---
Finished <<< launch_system_modes [1.53s]

These warnings show the tests_require option is expired. But the python is the default package with ubuntu 22.04 and setuptools is installed by pip.

And then I use colcon test to test this project, there were also some warnings.

Here is the output about the command colcon test:

Starting >>> launch_system_modes

/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'
  warnings.warn(msg)

Ran 0 tests in 0.000s

OK

Finished <<< launch_system_modes [0.72s]

It seems like that there were no python testing programs to run and no result file pytest.xml was generated in build directory.

Then I tried to modify the setup.py file in package launch_system_modes and replaced the option tests_require with extras_require.

Finally it can be built and test correctly.

Here is the modified content in setpu.py file:

tests_require=['pytest'],  # remove
extras_require={
        'test': ['pytest'],
 },  # add

But there are some format errors after running colcon test. Here is the result:

launch_system_modes.log

Now the python and setuptools version are updated very quickly, could you tell me if it is necessary to replace the tests_require option to adapt to the current environment.

Thanks!
