uvu has minimal dependencies and supports both async/await style tests and ES modules, but it’s not immediately clear to me why it benchmarks so well against the likes of Jest and Mocha.

~> "jest"  took  1,630ms  (861  ms)
~> "mocha" took    215ms  (  3  ms)
~> "tape"  took    132ms  (  ???  )
~> "uvu"   took     74ms  (  1.4ms)

The benchmark suites are pretty basic, so it’d be cool to see a “production” grade library or application port their test suite to uvu for comparison.
