Constructor Details

This class inherits a constructor from MiniTest::Unit::TestCase

Class Method Details

.bench(name, &block) ⇒ Object

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 'lib/minitest/benchmark.rb', line 352

def self.bench name, &block
  define_method "bench_#{name.gsub(/\W+/, '_')}", &block
end

.bench_performance_constant(name, threshold = 0.99, &work) ⇒ Object

Create a benchmark that verifies that the performance is constant.

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

    assert_performance_constant threshold, &work
  end
end

.bench_performance_exponential(name, threshold = 0.99, &work) ⇒ Object

Create a benchmark that verifies that the performance is exponential.

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

    assert_performance_exponential threshold, &work
  end
end

.bench_performance_linear(name, threshold = 0.99, &work) ⇒ Object

Create a benchmark that verifies that the performance is linear.

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

  end
end

.bench_range(&block) ⇒ Object

Specifies the ranges used for benchmarking for that class.

bench_range do
  bench_exp(2, 16, 2)
end

See Unit::TestCase.bench_range for more details.
