• 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 >>> fogros2 
/home/qiguanxiao/.local/lib/python3.10/site-packages/setuptools/_distutils/dist.py:261: UserWarning: Unknown distribution option: 'tests_require'

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.

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 fogros2 fogros2_examples 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

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!
