Closes #20

Hi @mecm1993 👋

Thanks for your proposal. 👍

For this issue, I would like to enable a more useful "autotest".

• Could docker container run -it --rm --entrypoint "" $IMAGE_NAME cat /etc/alpine-release be in error?
• Could docker container run -it --rm --entrypoint "" $IMAGE_NAME chromium-browser --version be in error?

For example, we could compare the version written in the README? or launch one of the examples and compare the results.

What do you think? 😊

Thanks again for your contribution.

It sounds good to me, however, I am not sure about testing the examples because the main focus should only be on the alpine-chrome image alone I think it could lead to false-positive in some scenarios. Is that ok with you?

For info, set -e Exit immediately if a command exits with a non-zero status. Let's try with your proposal and improve the testing part in the future. 👍
