Hello, I have another question: what should I do if the Docker tests on Git fail because the image is too large?

How large is it? Is it because of baked in reference data or just a lot of code? Large images may cause various issues for people so if addressable, it's probably good to avoid having such.

I am using image, provided by developers of the tool. The image is about 25 GB. It does have some data that is required by packages installed inside, but it is not that big, about 3GB. Most of the space is taken by package itself and dependencies.

That's quite large and I don't see any good way of dealing with it if it can't be made smaller.
