Question

升级后，我发现相同的几种测试方法都失败了，所以我想自动测试那些而不是所有类中的所有方法。我想列出每个类 - 方法对（例如TestBlogPosts.test_publish，TestUsers.test_signup）并将它们作为测试套件一起运行。无论是在文件中还是在命令行中，我都不在乎。

我知道these techniques to run several entire classes，但我在这里寻找更精细的粒度。（类似于命令行中的-n / pattern / - 运行测试方法的子集 - 但跨多个类。）

您可以放弃minitest/autorun并使用自定义的测试选择调用Minitest.run。

一个例子：

gem 'minitest'
require 'minitest'
#~ require 'minitest/autorun' ##No!

#Define Test cases. 
#The `puts`-statements are kind of logging which tests are executed.
class MyTest1 < MiniTest::Test
  def test_add
    puts "call %s.%s" % [self.class, __method__]
    assert_equal(2, 1+1)
  end
  def test_subtract
    puts "call %s.%s" % [self.class, __method__]
    assert_equal(0, 1-1)
  end
end
class MyTest2 < MiniTest::Test
  def test_add
    puts "call %s.%s" % [self.class, __method__]
    assert_equal(2, 1+1)
  end
  def test_subtract
    puts "call %s.%s" % [self.class, __method__]
    assert_equal(1, 1-1)  #will fail
  end
end

#Run two suites with defined test methods.
Minitest.run(%w{-n /MyTest1.test_subtract|MyTest2.test_add/})  #select two specific test method

结果：

Run options: -n "/MyTest1.test_subtract|MyTest2.test_add/" --seed 57971

# Running:

call MyTest2.test_add
.call MyTest1.test_subtract
.

Finished in 0.002313s, 864.6753 runs/s, 864.6753 assertions/s.

2 runs, 2 assertions, 0 failures, 0 errors, 0 skips

当您拨打以下测试时：

Minitest.run(%w{-n /MyTest1.test_subtract/})  #select onespecific test method
puts '=================='
Minitest.run(%w{-n /MyTest2.test_add/})  #select one specific test method

然后你得到

Run options: -n /MyTest1.test_subtract/ --seed 18834

# Running:

call MyTest1.test_subtract
.

Finished in 0.001959s, 510.4812 runs/s, 510.4812 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips
==================
Run options: -n /MyTest2.test_add/ --seed 52720

# Running:

call MyTest2.test_add
.

Finished in 0.000886s, 1128.0825 runs/s, 1128.0825 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

Minitest.run采用您在命令行中使用的相同参数。因此，您可以在选择中使用-n选项，例如/MyTest1.test_subtract|MyTest2.test_add/。

您可以使用不同的Minitest.run定义来定义不同的任务或方法，以定义您的测试套件。

注意：您加载的测试文件不能包含require 'minitest/autorun'。
