getting capybara to work with vue.js in rails

Question

I recently added a feature in vuejs and am having trouble testing it.

I created a spec file for simply visiting the page but anything on my html that has logic such as a v-show does not get rendered in the test. I added an onload to see if it might render

window.onload = function () {
  new Vue({
    el: 'body',
    ....
  });
}

but upon running the spec I still get multiple vue warnings like this:

[Vue warn]: Error when evaluating expression "settingIds.includes(setting.id)": TypeError: 'undefined' is not a
function (evaluating 'scope.settingsIds.includes(scope.setting.id)')`

Note: I am using localstorage which some of my view logic depends on and I'm not sure if capybara supports it

Answer 1

假设settingsIds是一个数组-包括PhantomJS或IE不支持的ES7方法（您应该运行的最新PhantomJS 2.1.1，支持的是ES5）-您需要不使用ES6 /来重写代码7种方法，将其转码为ES5或使用poltergeist扩展选项进行polyfill
