Question

我写了一个像这样的测试

describe('execCommand', function () {
    it('should call document.execCommand', function () {
        spyOn(document, 'execCommand').and.callThrough();
        expect(document.execCommand).toHaveBeenCalledWith('foreColor', false, 'red');
        document.execCommand('foreColor', false, 'red');
    });
});

但是Expected spy execCommand to have been called with [ 'foreColor', false, 'red' ] but it was never called.失败了，我不知道为什么？

请帮忙。

注意：我使用grunt-contrib-jasmine 0.9.2

运行它

Jasmine的expect函数是当时的断言，而不是将在it块结束时运行的断言，切换顺序以使其工作：

describe('execCommand', function () {
  it('should call document.execCommand', function () {
    spyOn(document, 'execCommand').and.callThrough();
    document.execCommand('foreColor', false, 'red');
    expect(document.execCommand).toHaveBeenCalledWith('foreColor', false, 'red');
  });
});

不调用Jasmine spy document.execCommand
