How to report phpunit test that run inside container

General
1

I have a lamp application, and at the end of my Dockerfile I restart the apache

CMD /user/sbin/apache2ctl -D FOREGROUND

And my question is, if I want to run a phpunit test inside the container, and how do I know if the test is passed or not ??

I thought of the following, is that a correct way to do it ?

For example, mount a volume from the host, and write the php unit test result to the mounted volume, so that I can know it is passing or not?

If not, what would be the common way ( correct way ) of doing that ?

Thanks in advance
