testing - 使用 Webpack+karma+etc 进行 Redux 异步测试

Question

我试图做一个异步 Action 测试，但失败得很惨:(

有问题的测试是这个:https://github.com/persocon/destiny-weekly/blob/test/test/actions/index.spec.jsx

我收到此错误消息:

1) fill in GET_OPTIONS when fetching all options is done Async Actions undefined is not an object (evaluating 'store.dispatch(actions.getOptions()).then') /Users/persocon/Projects/destiny-weekly/test/test.bundle.js:14669:42 <- webpack:///test/actions/index.spec.jsx:49:7

我不知道那是什么意思，如果这是为了帮助我，我会比以往任何时候都更加困惑。

更新

必须在操作本身而不是我使用的 $.get 上实现获取，但现在我收到一个指向我的操作的新错误:v 即使它在浏览器上工作:

1) fill in GET_OPTIONS when fetching all options is done Async Actions Can't find variable: fetch /Users/persocon/Projects/destiny-weekly/test/test.bundle.js:42473:9 <- webpack:///src/app/javascript/actions/index.jsx:32:9 /Users/persocon/Projects/destiny-weekly/test/test.bundle.js:15691:23 <- webpack:///~/redux-thunk/lib/index.js:12:0 /Users/persocon/Projects/destiny-weekly/test/test.bundle.js:14669:20 <- webpack:///test/actions/index.spec.jsx:48:19

更新 2 Action 代码:

const setOptions = (result) => {
return {
    type: 'GET_OPTIONS',
    options: result
}
}

const getOptions = () => {


return dispatch => {
    dispatch(startLoading())
    return fetch('/api/selectActivity')
            .then(response => response.json())
            .then( json => {
                dispatch(doneLoading());
                json.unshift({advisorTypeCategory: "Selecione Uma Atividade", identifier: "", disabled: "disabled"});
                dispatch(setOptions(json));
            }
        )
 }
}

是的，Async Action Creators Example 使用的是“fetch”，这有点做作，但理论上应该可行。一个简单的解决方案可能是用这个 isomorphic fetch library 来实现它.祝你好运!
