如何对 Leaflet JS 地图进行单元测试?

How can you unit test Leaflet JS maps?

推荐答案

我真的在同一个问题上挣扎.这是使用js测试库"mocha"进行的一些测试的链接: http://blog.mathieu-leplatre.info/test-your-leaflet-applications-with-mocha.html

I am really struggling with the same issue. Here is a link to some testing with the js test library 'mocha': http://blog.mathieu-leplatre.info/test-your-leaflet-applications-with-mocha.html

但是，我遇到了进一步的问题，试图调用传单的catch all'L'函数.首先是这样:

However, I ran into further issues trying to call leaflet's sort of catch all 'L' function. The first was this:

}(window, document));
  ^

ReferenceError: window is not defined

我用以下代码纠正了该问题:

I remedied that issue with this bit of code:

// Create globals so leaflet can load
GLOBAL.window = {};
GLOBAL.document = {
  documentElement: {
    style: {}
  },
  getElementsByTagName: function() { return []; },
  createElement: function() { return {}; }
};
GLOBAL.navigator = {
  userAgent: 'nodejs'
};
GLOBAL.L = require('leaflet');

Node.js传单错误

在处理了该问题之后，我遇到了诸如'L.map('')之类的实际功能的问题.该函数似乎需要一个具有id的元素才能正常运行.

After I dealt with that issue, I am running into a problem with the actual functions, such as 'L.map(''). It seems that the function needs an element with an id to function correctly.

这是我收到的该函数的错误:

Here is the error I received for that function:

        return (typeof id === 'string' ? document.getElementById(id) : id);
                                                  ^

TypeError: document.getElementById is not a function

我希望这对您有所帮助，我当然还没有弄清楚.

I hope this helps you a little bit, I certainly still haven't figured it out.
