class Minitest::BenchSpec - minitest：Ruby 标准库文档

bench(name, &block) 点击切换源代码

用于定义一个新的基准测试方法。通常您不会直接使用它，它适用于需要编写新的性能曲线拟合（例如：您需要一个特定的多项式拟合）的人。

有关如何使用此方法的示例，请参见 ::bench_performance_linear。

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 355
def self.bench name, &block
  define_method "bench_#{name.gsub(/\W+/, "_")}", &block
end

bench_performance_constant(name, threshold = 0.99, &work) 点击切换源代码

创建一个基准测试，验证性能是否为常量。

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

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 399
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) 点击切换源代码

创建一个基准测试，验证性能是否为指数级。

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

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 414
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) 点击切换源代码

创建一个基准测试，验证性能是否为线性。

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

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 384
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) 点击切换源代码

创建一个基准测试，验证性能是否为对数级。

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

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 429
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) 点击切换源代码

创建一个基准测试，验证性能是否为幂函数。

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

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 444
def self.bench_performance_power name, threshold = 0.99, &work
  bench name do
    assert_performance_power threshold, &work
  end
end

bench_range(&block) 点击切换源代码

为该类指定用于基准测试的范围。

bench_range do
  bench_exp(2, 16, 2)
end

有关更多详细信息，请参见 Minitest::Benchmark#bench_range。

调用超类方法 Minitest::Benchmark::bench_range

# File minitest-5.25.4/lib/minitest/benchmark.rb, line 368
def self.bench_range &block
  return super unless block

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