Question

方法1： -

test.rb

class Test < Test::Unit::TestCase
  def test_sample
    assert_true(test)
    assert_equal(a,b)
  end
end

结果： - 完成时间为38.329532529秒。

1 tests, 2 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
100% passed

方法2： -

test.rb

class Test <  Test::Unit::TestCase
require 'helper'
include AssertionHelper
  def test_sample
    test_assertion
  end
end

helper.rb

include Test::Unit::Assertions
module AssertionHelper
  def test_assertion
    assert_true(test)
    assert_equal(a,b)
  end
end

结果： -

Finished in 38.329532529 seconds.

1 tests, 2 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
100% passed

方法3： -

test.rb

class Test <  Test::Unit::TestCase
require 'helper'
  def test_sample
    AssertionHelper.test_assertion()
  end
end

helper.rb

 include Test::Unit::Assertions
    module AssertionHelper
      def self.test_assertion
        assert_true(test)
        assert_equal(a,b)
      end
    end

结果： -

Finished in 38.329532529 seconds.

1 tests, 0 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
100% passed

当使用方法3时，我得到断言计数为＆＃34; 0＆＃34;而不是＆＃34; 2＆＃34;。

我可以使用方法2将断言计数设为2吗？

Answer 1

您可以将当前的TestCase传递给您的模块，如下所示：

sample_test.rb：

require 'test-unit'
require 'helper'

def a; true ; end
def b; true ; end
def test; true ; end

class SampleTest < Test::Unit::TestCase
    def test_sample
        AssertionHelper.my_assertion(self)
    end
end

helper.rb：

module AssertionHelper   
    def self.my_assertion(test_case)
      test_case.instance_exec do
        assert_true(test)
        assert_equal(a, b)
      end
    end
end

Answer 2

很抱歉，但我无法重现您的情况，请提供Test::Unit版本和您的红宝石版本？最重要的是你的Gemfile与Gemfile.lock。以下设置适用于我（我使用ruby 2.2.0和测试单元3.0.8）：

ruby-2.2.0 in ~/projects/test-unit ♥ tree
.
├── Gemfile
├── Gemfile.lock
└── test
    ├── helper.rb
    └── sample_test.rb

1 directory, 4 files

ruby-2.2.0 in ~/projects/test-unit ♥ cat Gemfile
# A sample Gemfile
source "https://rubygems.org"

# gem "rails"
gem 'test-unit', '~> 3.0.8'
ruby-2.2.0 in ~/projects/test-unit ♥ cat Gemfile.lock
GEM
  remote: https://rubygems.org/
  specs:
    power_assert (0.2.2)
    test-unit (3.0.8)
      power_assert

PLATFORMS
  ruby

DEPENDENCIES
  test-unit (~> 3.0.8)

sample_test.rb：

require 'test-unit'

def a; true ; end
def b; true ; end
def test; true ; end

class SampleTest < Test::Unit::TestCase
    require 'helper'
    include AssertionHelper
    def test_sample
        my_assertion
    end
end

helper.rb：

module AssertionHelper
    def my_assertion
        assert_true(test)
        assert_equal(a, b)
    end
end

正如预期的那样，运行testrb会产生2个断言。

ruby-2.2.0 in ~/projects/test-unit ♥ testrb 
Loaded suite .
Started
.

Finished in 0.000828 seconds.

1 tests, 2 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
100% passed

1207.73 tests/s, 2415.46 assertions/s
ruby-2.2.0 in ~/projects/test-unit ♥

UPDATE ：这实际上很奇怪你没有得到任何错误（在你的方法3上），因为我得到了这个：NoMethodError: undefined method 'assert_true' for AssertionHelper:Module这是真的，因为{{1没有实现任何其他方法，您不能在其上运行任何AssertionHelper方法。只需使用我上面的代码（你的方法2），你应该没事。如果你仍然好奇可以做些什么，看看Test::Unit::Assertions，还有很多内置的断言定义，也许你觉得有用。

或者，更好的是，使用MiniTest或RSpec，因为Test :: Unit is deprecated并且只留在标准库中用于传统测试套件。
