我正在创建一个使用 jstree 的 rails 应用程序。现在我正在尝试在 rspec 测试中测试 jstree 的功能,使用 capybara 和 selenium 驱动程序(js:true)。测试是:
scenario "the object associated with the data-pane is selected in the tree", js: true do
visit surveyor_path
using_wait_time(20) { expect(page).to have_selector("##{obj.class.name}_#{obj.id.to_s}") }
end
这是在 shared_example 中,obj 是与测试相关的对象(在本例中为测量员)。我的 js 树应该生成 id 像“_”的节点。所以我期待像“Surveyor_1”这样的东西。
运行时,我收到以下错误:
Failure/Error: Unable to find matching line from backtrace

事情是这样的,/surveyors/themes/default/style.css
首先不应该是一条路线。它正在寻找的资产位于assets/themes/default/style.css
. 这是一个特定于 js-tree 的样式表。在测试中插入一些调试器语句,我可以验证页面确实有选择器。如果页面确实有选择器,我只会得到异常......也就是说,如果我将内容更改为have_selector
to "BadSelector"
,测试将定期失败(没有找到选择器)。js-tree 功能在手动查看时有效。
在此先感谢您的帮助
