class Minitest::BenchSpec - minitest: Ruby Standard Library Documentation

bench(name, &block) click to toggle source

This is used to define a new benchmark method. You usually don’t use this directly and is intended for those needing to write new performance curve fits (eg: you need a specific polynomial fit).

See ::bench_performance_linear for an example of how to use this.

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 357
def self.bench name, &block
  define_method "bench_#{name.gsub(/\W+/, "_")}", &block
end

bench_performance_constant(name, threshold = 0.99, &work) click to toggle source

Create a benchmark that verifies that the performance is constant.

describe "my class Bench" do
  bench_performance_constant "zoom_algorithm!" do |n|
    @obj.zoom_algorithm!(n)
  end
end

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 401
def self.bench_performance_constant name, threshold = 0.99, &work
  bench name do
    assert_performance_constant threshold, &work
  end
end

bench_performance_exponential(name, threshold = 0.99, &work) click to toggle source

Create a benchmark that verifies that the performance is exponential.

describe "my class Bench" do
  bench_performance_exponential "algorithm" do |n|
    @obj.algorithm(n)
  end
end

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 416
def self.bench_performance_exponential name, threshold = 0.99, &work
  bench name do
    assert_performance_exponential threshold, &work
  end
end

bench_performance_linear(name, threshold = 0.99, &work) click to toggle source

Create a benchmark that verifies that the performance is linear.

describe "my class Bench" do
  bench_performance_linear "fast_algorithm", 0.9999 do |n|
    @obj.fast_algorithm(n)
  end
end

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 386
def self.bench_performance_linear name, threshold = 0.99, &work
  bench name do
    assert_performance_linear threshold, &work
  end
end

bench_performance_logarithmic(name, threshold = 0.99, &work) click to toggle source

Create a benchmark that verifies that the performance is logarithmic.

describe "my class Bench" do
  bench_performance_logarithmic "algorithm" do |n|
    @obj.algorithm(n)
  end
end

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 432
def self.bench_performance_logarithmic name, threshold = 0.99, &work
  bench name do
    assert_performance_logarithmic threshold, &work
  end
end

bench_performance_power(name, threshold = 0.99, &work) click to toggle source

Create a benchmark that verifies that the performance is power.

describe "my class Bench" do
  bench_performance_power "algorithm" do |n|
    @obj.algorithm(n)
  end
end

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 447
def self.bench_performance_power name, threshold = 0.99, &work
  bench name do
    assert_performance_power threshold, &work
  end
end

bench_range(&block) click to toggle source

Specifies the ranges used for benchmarking for that class.

bench_range do
  bench_exp(2, 16, 2)
end

See Minitest::Benchmark#bench_range for more details.

Calls superclass method Minitest::Benchmark::bench_range

# File minitest-5.16.3/lib/minitest/benchmark.rb, line 370
def self.bench_range &block
  return super unless block

  meta = (class << self; self; end)
  meta.send :define_method, "bench_range", &block
end
