水豚是否会忽略before（：all）块中的代码？ 我该怎么办？
[英]Does capybara ignore code in a before(:all) block? What can I do about this?
问题描述
I completely understand why you should use before(:each) and make all expectations independent of each other, but I'm just interested into why this would happen: 
我完全理解为什么您应该使用before（：each）并使所有期望彼此独立，但是我只是想知道为什么会这样：
before(:each) { visit "/" } # Selenium visits the root path of my app
before(:all) { visit "/" } # Selenium doesn't even open firefox.
Nothing happens with the background(:all) , but if I raise an exception in the same context, Selenium does open firefox and visits this weird empty file. background(:all)没有任何反应，但是如果我在相同的上下文中引发异常，Selenium确实会打开Firefox并访问此奇怪的空文件。

So does anyone know if Capybara actively ignores code in a before block(:all), and if so, how can I get it to not ignore code in a before(:all)? 那么，有谁知道Capybara是否主动忽略before块（：all）中的代码？
This isn't really serious project, but I was thinking about benchmarking with Capybara, so it would be nice if someone showed me a way to get Capybara working with a before(:all). 这不是一个很认真的项目，但是我正在考虑与Capybara进行基准测试，因此如果有人向我展示一种使Capybara与before（：all）一起工作的方法，那将是很好的。

There is a distinct difference in these two before blocks. 这两个before块有明显的不同。
before(:each) is evaluated before every test. before(:each)每次测试之前评估before(:each) 。
before(:all) is evaluated before running your tests. before(:all)运行测试之前，对before(:all)进行评估。 Once. 一旦。
You should probably be using before(:each) 您可能应该使用before(:each)
