Question

我在 firefox 上执行我的脚本并收到一个 Firefox 升级通知，我关闭了。再次开始执行，但出现如下错误，

我的配置文件如下，

var HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter');

var reporter = new HtmlScreenshotReporter({
  dest: 'target/screenshots',
  filename: 'Report.html',
  reportTitle: 'Execution Report',
  showSummary: true,
  showQuickLinks: true,
  pathBuilder: function(currentSpec, suites, browserCapabilities) {
  // will return chrome/your-spec-name.png
  return browserCapabilities.get('browserName') + '/' + currentSpec.fullName;
 }
 });

exports.config = {

directConnect: true,
//seleniumAddress: 'http://localhost:4444/wd/hub',
capabilities: {'browserName': 'firefox'},
framework: 'jasmine',
specs: ['Login_spec2.js','Article_spec.js'],
allScriptsTimeout: 200000,
getPageTimeout: 200000,
jasmineNodeOpts: {
    defaultTimeoutInterval: 200000
},

 // Setup the report before any tests start
  beforeLaunch: function() {
    return new Promise(function(resolve){
    reporter.beforeLaunch(resolve);
  });
 },
  // Close the report after all tests finish
  afterLaunch: function(exitCode) {
   return new Promise(function(resolve){
    reporter.afterLaunch(resolve.bind(this, exitCode));
  });
},

onPrepare: function() {
    var width = 1300;
    var height = 1200;
    browser.driver.manage().window().setSize(width,height);
    jasmine.getEnv().addReporter(reporter);
    afterAll(function(done) {
        process.nextTick(done);
    })
 }

 };

其他细节是:其他细节如下:protractor@3.2.2, nodeVersion: 4.2.4, npmVersion: 2.14.12, jasmine: 2.4.1, selenium-webdriver: 2.52.0, firefox: 47

请帮我解决这个问题。

您必须执行以下操作才能使其正常工作:

• 将 protractor 升级到最新的 3.3.0 版本，该版本还将带来 selenium-webdriver 2.53
• 降级firefox to version 46并且暂时不要让它更新(有 compatibility issues )
