我已经附上了日志，但是，基本上，我整天都在打这个。它在大多数情况下成功，但随后失败，没有可预测的模式。
这些也是非常容易的水豚测试：

我不知道是什么原因引起的。我很欣赏任何见解。
parallel /some/binary '{=s/..$//=}'/{} ::: 20131017 20131018
答案 0 :(得分：3)
像这样的零星错误通常是由规范中的计时问题引起的。通常来自页面占用时间过长的页面上不存在的元素。
我发现修复这些类型错误的最简单方法是将您的期望包装在within block中。然后，您的测试将等到找到用于内部块的选择器，然后才能达到您的期望。
像这样添加一个内部块
t.visit '/signup'
within "form" do
t.fill_in 'user_email', :with => email
t.fill_in 'user_password', :with => password
t.fill_in 'user_password_confirmation', :with => password
t.click_on 'Create Login'
end
expect(page).to have_content('Welcome!')
