使用JavaScript禁用地理位置浏览器

Question

I'm writing an integration test using QUnit, and in my webapp if geolocation is not available, (I use if (navigator.geolocation) to detect if is present or not, but I want to disable it in order to implement the test when geolocation is not available.

I tried navigator.geolocation = undefined but unfortunately it didn't work.

You can't really "disable" navigator.geolocation since it's a read-only property.

Instead, you could create a wrapper that checks for certain functionality and then mock it up for your tests.

var supports = {
  geolocation: !!navigator.geolocation // will be `true` if geolocation is defined
};

// In your tests...
supports.geolocation = false;
executeTest();
