Method: MiniTest::Unit::TestCase#assert_performance_exponential

Defined in:
lib/minitest/benchmark.rb

#assert_performance_exponential(threshold = 0.99, &work) ⇒ Object

Runs the given work and asserts that the times gathered fit to match a exponential curve within a given error threshold.

Fit is calculated by #fit_exponential.

Ranges are specified by ::bench_range.

Eg:

def bench_algorithm
  assert_performance_exponential 0.9999 do |x|
    @obj.algorithm
  end
end
