【问题描述】：

我的测试运行良好，但是当在 OnComplete 方法中调用 browser.getCapabilities(); 时，它会引发错误。

    //HTMLReport called once tests are finished
  onComplete: function () {
    var browserName, browserVersion;
    browser.getCapabilities();
    capsPromise.then(function (caps) {
      browserName = caps.get('browserName');
      browserVersion = caps.get('version');
      platform = caps.get('platform');
      var HTMLReport = require('protractor-html-reporter-2');
      testConfig = {
        reportTitle: 'Protractor Test Execution Report',
        outputPath: './reports',
        outputFilename: 'ProtractorTestReport',
        screenshotPath: '..//screenshots',
        testBrowser: browserName,
        browserVersion: browserVersion,
        modifiedSuiteName: false,
        screenshotsOnlyOnFailure: true,
        testPlatform: platform
      };
      new HTMLReport().from('xmlresults.xml', testConfig);
    });

控制台：

【问题讨论】：

浏览器是否在此方法之前未定义？

标签： javascript selenium jasmine protractor

【解决方案1】：

我的 conf.js 文件顶部的以下代码是罪魁祸首。由于我没有添加它，因此不确定它是如何添加到那里的。

const { browser } = require('protractor');
