使用集成的QUnit測試framweork我需要測試是否訪問路由會導致拋出錯誤。在Ember.js中引發錯誤的測試
路線中有一個把手助手,在某些情況下應該拋出一個錯誤(失敗斷言)。我該如何測試這個錯誤是否被拋出?
這是我走到這一步:
test('throws, if the SVG is missing', function() {
throws(visit('/missing'), Error, "has thrown an Error");
});
但它不工作,因爲錯誤沒有被抓到throws(...)
和泡沫到測試框架,這標誌着本次測試爲失敗。
這是測試輸出:

由於visit('/missing')
回報的承諾,人們會認爲使用.then(success, error)
會的工作,但事實並非如此。
截至Ember 2.11,斷言拋出似乎不再是一件事情。 https://github.com/emberjs/ember.js/pull/14898 – snewcomer 2017-04-09 01:44:05
