Adding Visual Expectations for Plotting Functions

[mariusbarth]

Hi @crsh,

It is still one of my aims to refactor the family of apa_*plot() functions in the future. Actually, I already drafted a powerful approach, but the changes are so extensive that it is practically impossible to review these changes all at once and I also want to take some precautions not to break older code.

Therefore, I thought it is wise to first add visual expectations (via the vdiffr package) before I start adding theses changes one by one.

This PR is intended to get github actions running, and to gain some experience with vdiffr. I will require your review as soon as I have the impression that we can add these tests to the main branch. In the meantime, any feedback on how to improve the testing pipeline is highly appreciated.

Hah, great. I've been 'considering' this for ages. Thanks for taking the initiative!
