I want to determine that an input field with id="foo" exists:
我想确定存在id =“foo”的输入字段:
<input id="foo" ... />
And I also want to ensure that under certain conditions another input field with id="bar" does not exist.
我还想确保在某些条件下不存在id =“bar”的另一个输入字段。
2 个解决方案
#1
Exists:
expect(page).to have_css('#bar')
Doesn't exist:
expect(page).to have_no_css('#bar')
Note: Don't use expect(page).to_not have_css, as that will wait for your element to appear.
注意:不要使用expect(page).to_not have_css,因为它会等待你的元素出现。
An explanation of expect and negative forms like has_no_selector? and not has_selector? can be found in Capybara's Asynchronous JavaScript documentation.
对has_no_selector等期望和否定形式的解释?而不是has_selector?可以在Capybara的异步JavaScript文档中找到。

To determine that a particular input field exists, use:
要确定存在特定输入字段,请使用:
assert has_xpath?("//input[@id='foo']")
To determine that a particular input field does not exist, use one of:
要确定特定输入字段不存在,请使用以下方法之一:
assert has_no_xpath?("//input[@id='bar']")
refute has_xpath?("//input[@id='bar']")
