Visual Studio中的JS测试与Chutzpah失败，但在浏览器中执行时成功

Question

我在Visual Studio 2017中遇到了Chutzpah的问题。我在浏览器（Firefox，Edge＆amp; Chrome）中成功运行了jQuery代码，但在使用Chutzpah在VS中运行时失败了。< / p>

首先我的设置：

• Jasmin版本2.5.2
• Jasmin-jQuery版本2.1.1
• jQuery版本3.1.1
• Chutzpah 4.3.4
• Visual Studio 2017版本15.1

我的测试用Jasmin编写，扩展名为Jasmin-jQuery。

var progressbarHTML = '<a id="progressbarCaption"></a>' +
       '<div id="progressContainer">' +
       '<div id="progressArea">' +
       '<div id="progressbar">' +
       '<div id="progresslabel" class="progress-label">' +
       '</div></div></div></div>';

describe("CSS Classes are loaded?", function() {
  beforeEach(function() {
    var html = '<div id="controlAddIn">' + progressbarHTML + '</div>';
    setFixtures(html);
    environment = {"Platform" : 0};
    InitializeControl();
  });

  it("Is CSS for progressbarCaption set", function() {
    expect($("#progressbarCaption")).toHaveClass("progressbarCaptionWidowsClient");
  });

  it("Is CSS for progressContainer set", function() {
    expect($("#progressContainer")).toHaveClass("progressContainerWindowsClient");
  });

  it("Is CSS for progresslabel set", function() {
    expect($("#progresslabel")).toHaveCss({'top': "1px"});
  });

});

当我在浏览器中运行测试时，我得到了

Test in Browser

这完全没问题。但是当我在VS中运行测试时，右键单击HTML文件并“运行JS测试”。我得到了

Test 'CSS Classes are loaded?:Is CSS for progresslabel set' failed
    Expected ({ 0: HTMLNode, length: 1 }) to have css Object({ top: '1px' }).

突然间，最后一次测试失败，我不明白为什么。
