class Minitest::ShellPs
Return the resident set size (RSS) in kB.
This is fairly foolproof, but probably not the most accurate measure possible since shelling out most likely affects memory usage and isn’t terribly efficient.
Other strategies could be implemented in the future, for instance see NewRelic’s samplers: github.com/newrelic/rpm/blob/release/lib/new_relic/agent/samplers/memory_sampler.rb
