Docker-compose mount test results inside a local volume

I have python tests that generate the results of the tests as HTML and XML files. When I run docker-compose, I want to find these results and mount them in a local volume.

docker-compose.yml

version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - myLocalVolumes:/my/url/to/tests/results
volumes:
   myLocalVolumes

I am using a MacBook. Any tips on how to find the URL of these test results.
I think it has to be taken from inside the container or stored somewhere in the computer.

    The solution is there is a folder named results inside the project. That folder contains all the results of the tests as HTML and XML files. To mount that data, we will do: myLocalVolumes:/results. The complete docker-compose.yml will be

    version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - myLocalVolumes:/results
volumes:
   myLocalVolumes

    if your goal is to save test results. first find where the results are saved in the container. if your script/code write results to folder called results in the same working directory
    you should first find the working dir
    you can find it in the Dockerfile
    example:
    WORKDIR /project
    then mount the results directory to the docker volume

    version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - myLocalVolumes:/project/results
volumes:
   myLocalVolumes

    you will find volume in the path /var/lib/docker/volumes/myLocalVolumes
    or in more simple way you can mount to a folder in the host machine

    version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - ./results:/project/results

    if your script/code generates individual files with different unique names it’s better to modify the code to put results into a directory so you can mount them easily.
