Question

有这个html：

<!DOCTYPE html>
<html>
  <head>
    <meta content="my id" property="fb:app_id" />
    <meta content="app name" property="og:site_name" />
    <meta content="social post" property="og:type" />
    <meta content="bsa" property="og:title" />
    <meta content="bsa" property="og:description" />
    <meta content="http://will-ferrell.lvh.me:3000/" property="og:url" />
  </head>
</html>

尝试这样做：

expect(page).to have_selector :xpath, '//head/meta[@property="fb:app_id"]'
expect(page).to have_selector :xpath, '//head/meta[@property="og:site_name"]'
expect(page).to have_selector :xpath, '//head/meta[@property="og:type"]'
expect(page).to have_selector :xpath, '//head/meta[@property="og:title"]'
expect(page).to have_selector :xpath, '//head/meta[@property="og:description"]'
expect(page).to have_selector :xpath, '//head/meta[@property="og:url"]'

它不起作用。说它找不到选择器。知道为什么吗？

Answer 1

对于不可见元素，需要使用option - visible：false

示例：

expect(page).to have_selector :xpath, '//head/meta[@property="og:url"]', visible: false

XPath匹配器不适用于元标记
