Rails功能测试-从设置中排除方法
原标题:Rails Functional Test - excluding method from setup

这应该很简单,但我找不到任何例子。我在rails 3应用程序中有标准的功能测试(从ActionController::TestCase开始),看起来像:

test "see if 1+1=2" do
....
end

在顶部,我有一个设置方法:

setup do
  ......
end

如何排除方法?即。

setup :except => "see if 1+1=2" do
...
end

(以上不起作用obv)

问题回答

使用should a和上下文块,这样您就可以将使用设置的测试放在一个上下文中,而将不使用设置的考试放在另一个上下文或其他上下文块之外。

我对此也很好奇。在不安装和学习任何新gem的情况下,一个解决方法是在测试中定义一个私有函数

test "see if 1+1=2" do
  setup_situation_1
  ...
end

test "see if 1 * 1 = 1" do
  setup_situation_1
  ..
end

test "see if 1/1 = 1" do
  # no setup here
  ...
end

...

private
def setup_situation_1
  ...
end

这是我能想到的最枯燥的方法,而无需安装/学习新的gem——这对一些人来说可能是一个更好的解决方案,尤其是那些刚接触rails的人。然而,我找不到关于这个setup/do方法的文档——setup/do的“except”子句肯定是DRY er。
