使用Jasmine模拟chrome.storage.local函数

我在名为options.js的文件中包含以下代码。我需要使用Jasmine来模拟它。我需要测试在调用chrome.storage.local.set函数时是否调用save

在spec文件中,我有以下代码。但它不会调用options.js文件中的chrome函数。有人可以指出错误吗?

  beforeEach(function() {
    ctrl = new OptionCtrl(scope);
    chrome: {
      storage: {
        local: {
          set: function() {
          }
        }
      }
    }
  });

  it('should call storage on save', function() {
    spyOn(chrome.storage.local, 'set').and.callThrough();
    ctrl.save({data: 'check'}, 'check');
    expect(chrome.storage.local.set).toHaveBeenCalled();
  });

更新1 :保存功能实施

  save(data, successMessage) {
    chrome.storage.local.set(data, (error) => {
      if (error) {
        this.status('Error Occurred. Please refresh.', 1000, 100, 'danger');
      } else {
        this.status(successMessage, 1000, 100, 'success');
      }
    });
  }

茉莉花的收藏很简单:

var chrome = {
  storage: {
    local: {
      set: function() {}
    }
  }
}

function OptionCtrl() {
  this.save = function(data, callbackStr) {
    chrome.storage.local.set(data)
  }
}

describe('OptionCtrl', function() {
  var ctrl;

  beforeEach(function() {
    ctrl = new OptionCtrl({});
  });

  it('calls storage on save', function() {
    spyOn(chrome.storage.local, 'set').and.callThrough();
    var dataStub = {
      data: 'check'
    }

    ctrl.save(dataStub, 'check');

    expect(chrome.storage.local.set).toHaveBeenCalledWith(dataStub);
  });
