Test vizarr

[will-moore]

@joshmoore I assume we could test vizarr using a Docker container specified in this repo instead of in the vizarr repo, in order not to pollute that repo with OME's code?

Exactly. If there's a Dockerfile somewhere that does what you want, then you can follow https://github.com/ome/ome_zarr_test_suite/blob/main/scripts/omero_ms_zarr_fake . Otherwise, create a subdirectory there that contains a Dockerfile and we'll go from there. 👍

I was thinking of:

1. Using Docker with http-server to serve the test data (with cors).

2. Then checkout and build a particular branch of vizarr, or possibly use the PR builds e.g. PR 85 deploy-preview-85 to consume and display the data.

3. Finally, use pageres-cli to grab a browser screenshot of the app. Either this could be compared with a known valid screenshot, or some other simpler validation that at least the image is displayed.

I managed 1) OK, but failed with 3) - getting errors with puppeteer which referred me to https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md#running-puppeteer-in-docker but I didn't manage to get any of the solutions there working
