Cucumber/Capybara: check that a page does NOT have content?
提问by dB'
Using Cucumber and Capybara, is there a way to verify that a string is NOT present on a page?
使用 Cucumber 和 Capybara，有没有办法验证页面上不存在字符串？
For example, how would I write the opposite of this step:
例如，我将如何编写与此步骤相反的内容：
Then /^I should see "(.*?)"$/ do |arg1|
page.should have_content(arg1)
end
This passes if arg1is present.
如果arg1存在，则通过。
How would I write a step that failsif arg1is found?
如果找到，我将如何编写失败的步骤arg1？

There is a has_no_contentmatcher in Capybara. So you can write
has_no_content水豚有一个匹配器。所以你可以写
Then /^I should not see "(.*?)"$/ do |arg1|
page.should have_no_content(arg1)
end

In Rspec 3.4 currently (2016) this is the recommended way to test for not having content:
在 Rspec 3.4 当前（2016）中，这是测试没有内容的推荐方法：
expect(page).not_to have_content(arg1)
回答by Adam Sheehan
You can also use should_notif you want it read a little better:
如果你想让它读得更好一点，你也可以使用should_not：
Then /^I should not see "(.*?)"$/ do |arg1|
page.should_not have_content(arg1)
end

currently, you can use:
目前，您可以使用：
Then /^I not see "(.*?)"$/ do |arg1|
expect(page).to have_no_content(arg1)
end
And if the content is found in the page, your test is red
如果在页面中找到内容，则您的测试为红色

Oh, wait, I figured it out. This works:
哦，等等，我想通了。这有效：
Then /^I should see "(.*?)"$/ do |arg1|
page.has_content?(arg1) == false
end
