我在我的主模板中定义了一个全局变量，我用它来存储来自后端的信息位，例如环境上下文路径。我不能在服务中移动该变量。

I have a global variable defined in my main template, which I use to store information bits from the back end, such as the environment context path. I can't move that variable inside a service.

当我运行单元测试时，如何将该变量公开给Karma？

How can I expose that variable to Karma when I run the unit tests?

推荐答案

您可以在测试文件中声明该全局变量：

You either declare that global variable within your test file:

var global = "something"; describe('Your test suit', function() { ... });

或添加一个Javascript文件，将其定义到 karma.conf.js file：

or add a Javascript file where it's defined to your karma.conf.js file:

// list of files / patterns to load in the browser files: [ ..., 'file-containing-the-global-variable.js' ],
