Question

编写了一个步骤定义，用于在集合中使用rspec检查CSS元素。如果一个期望失败了整个场景炸弹，我甚至没有得到关于每个CSS元素是否存在的独特反馈（不幸的是，它是全部或全部！我不希望这样）

我有以下代码：

Then(/^I should see the following css selectors:$/) do |table|
  css_selectors = table.raw
  css_selectors.each do |selector|
    browser.element(:css=>selector.to_s).exists?.should be_true
  end
end

如果我测试一大堆元素，即：

Then I should see the following css selectors:
  |input#foo|
  |.bar     |
  |h#baz    |
  |span.batz|

如果任何元素不存在，我会遇到问题。救命啊！

Answer 1

您可以为包含失败的选择器的故障添加自定义消息。这是通过将第二个参数传递给should方法来完成的：

Then(/^I should see the following css selectors:$/) do |table|
  css_selectors = table.raw
  css_selectors.each do |selector|
    css_selector = selector[0].to_s
    browser.element(:css=>css_selector).exists?.should be_true, "Element not found: #{css_selector}"
  end
end

这会出现如下错误消息：

Element not found: input#foo (RSpec::Expectations::ExpectationNotMetError)

如果您还想确保运行所有选择器，则必须运行每个选择器，收集结果并对结果组执行断言。

Then(/^I should see the following css selectors:$/) do |table|
  css_selectors = table.raw

  # Collect any failed selectors
  failed_selectors = []
  css_selectors.each do |selector|
    css_selector = selector[0].to_s
    failed_selectors << css_selector unless browser.element(:css=>css_selector).exists?
  end

  # Check that none of the selectors failed
  failed_selectors.should be_empty, "The following elements were not found #{failed_selectors.join(', ')}"
end

你不能在场景中调用fail吗？
