CI workflow for benchmarking (Regression test)

[versable]

Hey @Try,

ever since #779 I have been pondering about how to implement a CI pipeline/workflow for regression tests. What hit me first was that it would be impossible to do so with assets.

I remembered there was a Demo-Version of Gothic 2 (I remembered having a copy of it on one of those PC gamer magazines…)

And lo and behold: There is a copy on WorldOfGothic [1].

Second hurdle was extracting the assets from the installer. After some hex dumping, I found some signatures pointing to a Wise Installer [2] installation.

After some digging, I found REWise [3], which worked like a charm out of the box, and it runs under OpenGothic without a hitch!

The next hurdle would be the DISPLAY, but as I recall this can be solved using Virtual Frame Buffers under Linux (Done it before professionally for converting HTML to PDF using wkhtml2pdf). So I will cross that bridge when I come to it.

HI,

This sound like an interesting building block for testing. However, do we have a use-case here?

For assets-related testing: there are unit-test (on synthetic data ofc) in ZenKit. And for graphics Tempest has unit tests as well. This leaves OpenGothic with only integration test-cases. Integration, I do usually manually by completing Bartok's hunt quest: it has dialog/follow/patching/combat and can excise many game mechanics at once - unfortunately have no good ideas on how-to automate it in a useful way.
