cargo-nextest
Ranked 2 of 8 testing frameworks by recommenders
Fast Rust test runner people say cuts test and CI times and just works. Caveat: per-test processes can't share connection pools, and endpoint security software can hang tests.

“I have --release build cycles on my local machine down to about three seconds”
“nextest is one of those things I never have to think about, because it always "just works" and I have no dramas with it.”
“Since cargo-nextest uses a separate process per test, there is no efficient way to share the connection pool.”
“I like how all this works, it's great.”
“I love nextest. But, perhaps because of the one-process per test approach, endpoint security solutions like CrowdStrike Falcon or Palo Alto Cortex tend to make computers hang whenever tests kick-in.”
“It's an excellent piece of engineering.”
“Those run thousands and thousands of tests thx to nextest and what feels like instantly”
“It is what allows our projects like rama [1] to run thousands and thousands of tests in a blink of an eye!”
“without it my CI could take hours”
“documentation at its best!”
“Tokio uses it for their tests in CI as well last I checked.”
“I love nextest, it's been great.”
“it represents my best foot forward for how Rust testing should be done”

“Thanks for cargo-nextest btw!”
