Are these changes just to more clearly show when the list of visible cars is being changed?

this is to fix a bug where the list of visible vehicles sometimes includes '' strings

is this line supposed to do anything?

This doesn't seem like it's sorted?

good point, I'll call the method here as well

I sort of agree with Nish, what is the point of tests like these? This is just copying code and checking that the code you've copied is the same. Note, this is meant constructively; I'm sure I'm missing something.

they're for two reasons:
- solidifying certain aspects of the codebase that we are not interested in developing on anymore. Personally for me, the environments feel very fragile as is.
- maintaining some level of confidence that an environment will train. since we cannot easily run RL tests to completion, we can at least ensure that the environments are still the same (I have lost a good deal of time trying to figure out what's changed in an old environment just to find out that I or someone else had introduced new bugs, probably when they were trying something locally)
generally speaking, tests for environments should cover more intricate methods, but the ones I tested were pretty generic, minus I guess testing the reset method for WaveAttenuationEnv

Okay, I'm convinced of the value of this for now. We should replace these later with some sort of regression testing (TBD).

So in conclusion, it's a saved version of the envs.

yup, I was thinking the same about regression testing. these could just be a sanity test for now

Broadly, what's the point of these tests of the envs? It seems like the code is copied from the original env and then we check that the code has been copied correctly. |

If this test is specific to the loop, it's a little misnamed
