我想知道使用聚合物的wct是否是ujnit测试组件的正确方法。顺便说一句，我马上就要回答我自己的问题了：我想我错过了添加wct浏览器遗留依赖项，我应该使用wct--npm test-l chrome（--npm statnds for avoid Bower，并依赖npm和test-l chrome avoid internetexplorer，这将失败，因为它依赖于我还没有使用的polyfills）我想知道使用聚合物的wct是否是ujnit测试组件的正确方法。顺便说一句，我马上就要回答我自己的问题了：我想我错过了添加wct浏览器遗留依赖项，我应该使用wct--npm test-l chrome（--npm statnds for avoid Bower，并依赖npm和test-l chrome avoid internetexplorer，这将失败，因为它依赖于我还没有使用的polyfills）
