Example

require 'leadfoot'

class SampleBench < Leadfoot::Case
  def measure_array_push
    arr = []

    measure("array push") do
      1_000.times do
        arr << 42
      end
    end
  end
end

SampleBench.new.run!

Result

Example

series "my first series" do
  setup do
    @x = 2
  end

  measure "gimme 5" do
    @x + 3
  end

  measure "2 seconds" do
    sleep 2
  end

  measure "fail on error" do
    raise "foo"
  end
end
