There was a problem hiding this comment.
I wonder if it might be better to bundle the static values into a single struct with a single lazy initializer; as it is a new Client has to be constructed for each group of related functions and that would collapse it down to a single one.
This is well into micro-optimization territory, though, so up to you if you want to implement that or merge as-is :)

RUST-1447
Removes all server round-trips from test client creation and instead caches client metadata in a number of lazy static variables in
src/test.rs. The changes outside ofsrc/test.rsandsrc/test/util.rsare largely search-and-replace; I also removed some checks related to 4.0 now that we don't support/test any lower server versions.
