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

Hers is the output of the command colcon build:

Starting >>> tracetools_image_pipeline
Starting >>> camera_calibration
Starting >>> depth_image_proc

This warning shows the tests_require option is expired. But the python and setuptools are default package with the ubuntu 22.04.

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 >>> tracetools_image_pipeline
Starting >>> camera_calibration
Starting >>> depth_image_proc

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 the camera_calibration package 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',  'requests' ],   # remove

extras_require={
        'test': ['pytest', 'requests'],
    },  # 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!
