Onprepare with jasmine reporters在使用IE执行时导致失败

在花了一段时间试图找出为什么我的测试一开始就失败了（仅适用于IE，chrome可以正常工作）之后，我发现这是由on prepare函数在代码的这一部分导致的：

  jasmine.getEnv().addReporter({
    specDone: function (result) {
      browser.getCapabilities().then(function (caps) 
      {
        var browserName = caps.get('browserName');
        browser.takeScreenshot().then(function (png) {
          var stream = fs.createWriteStream('./execution_results/reports/results/screenshots/' + browserName + '-' + result.fullName+ '.png');
          stream.write(new Buffer.from(png, 'base64'));
          stream.end();
        });
      });
    }
  });

如果我评论这一部分，测试将顺利进行。 我的登录页面没有角度，所以我关闭了登录的同步，然后再次打开，不确定这是否相关

在继续运行之前，如何强制量角器等待此部分完成

我已经尝试在promise（conf文件）中添加此代码以使量角器等待，但即使这样，我也得到了jasmine timeout“TimeoutError:wait timed out after 20000ms”，因此我相信我做得不对

我得到的错误是：

谢谢

最近，我在一个Jasmine reporter中也遇到了异步操作的问题，不幸的是，我不知道如何让他们在继续之前正确地等待承诺结果。如果其他人有这方面的信息，我也将非常感谢

我确实实现了一个使用全局变量和AfterAll钩子的工作，它能够正确地等待可能对您有用的承诺。 我假设您只需要结果的“fullname”属性，这样您就可以尝试这个

在onPrepare中声明全局属性，可以在reporter中为该全局变量赋值。在specStarted中为其指定spec fullname值，而不是specDone。然后，您可以在测试中创建屏幕截图，所有语句都可以正确地等待承诺结果

onPrepare: function () {   
   global.currentlyExecutingSpec = 'tbd';

  jasmine.getEnv().addReporter({
    specStarted: function (result) {
      currentlyExecutingSpec = result.fullName
    }
  })
  jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
    consolidateAll: true,
    savePath: './execution_results/reports/xml/',
    filePrefix: 'xmlresults'
  }));
}

在您的测试文件中

afterEach(function(){
  browser.getCapabilities().then(function (caps) 
  {
      var browserName = caps.get('browserName');
      browser.takeScreenshot().then(function (png) {
        var stream = 
        fs.createWriteStream('./execution_results/reports/results/screenshots/' + browserName + '-' + currentlyExecutingSpec + '.png');
        stream.write(new Buffer.from(png, 'base64'));
        stream.end();
      });
  };
});

你好非常感谢你。。这成功了！只是不得不从AfterAll改为afterEach，以便每个“It”都有一个屏幕截图，谢谢你的帮助
