javascript - 如何重写 Jasmine 2.0 自定义匹配器以与 Angular 1.5 一起使用？

Question

AngularJS tutorial有自定义匹配器在 Jasmine 中不起作用 starting from version 2.0 :

beforeEach(function(){
    this.addMatchers({
      toEqualData: function(expected) {
        return angular.equals(this.actual, expected);
      }
    });
  });

尝试修改匹配器失败并出现错误:

类型错误:未定义不是对象(正在评估“matcherCompare.apply”)

我的匹配器定义:

beforeEach(function(){
    jasmine.addMatchers({
      toEqualData: function(util, customEqualityTesters, actual, expected) {
        return angular.equals(actual, expected);
      }
    });
  });

Jasmine 2.0 custom matcher docs .

如何让它发挥作用？

Answer 1

beforeEach(function () {
    jasmine.addMatchers({
      toEqualData: function () {
        return {
          compare: function (actual, expected) {
            return {pass: angular.equals(actual, expected)};
          }
        };
      }
    });
  });
