Get rid of unused tests

[evan-forbes]

There are simulation tests that aren't testing anything, and are remnants of starport. While we certainly want equivalent tests, we will not be able to rely on the current simulation package or the testapp given that most of the application is stateless and those tools were not designed for that.

https://github.com/celestiaorg/celestia-app/blob/main/contrib/devtools/sims.mk
https://github.com/celestiaorg/celestia-app/blob/main/.github/workflows/release-sims.yml
https://github.com/celestiaorg/celestia-app/blob/main/.github/workflows/sims.yml

I'm also curious as to why these tests didn't start failing until recently

• sims passes on recent runs main: https://github.com/celestiaorg/celestia-app/actions/workflows/sims.yml?query=branch%3Amain
• sims failed on my branch for a known reason: https://github.com/celestiaorg/celestia-app/actions/runs/3012237262
• sims failed on https://github.com/celestiaorg/celestia-app/runs/8242496184?check_suite_focus=true
  • the -Enabled flag looks suspicious ref
  • likely not worth investigating / fixing if we don't need sims.mk

sims failed on my branch for a known reason: https://github.com/celestiaorg/celestia-app/actions/runs/3012237262

what was this reason?

yeah, I tried to remove flags, and it just kept giving the same error but the next flag/command

what was this reason?

go build fails because this draft PR depends on celestia-core changes. The draft PR doesn't modify go.mod because the celestia-core changes in this PR haven't been merged or released.

Research into sims

• osmosis has https://github.com/osmosis-labs/osmosis/blob/main/.github/workflows/sim.yml
• ignite CLI has docs on running simulations for scaffoled modules https://docs.ignite.com/kb/simapp#scaffold-a-simulation
• oof I just noticed this is closed by feat!: Refactor PrepareProposal to produce blocks using the non-interactive defaults #692
