Question

我遇到了一个带有以下e2e测试的量角器的奇怪错误：

it('should render vehicle title', () => {
  expect(vehicleTitle.getText()).toBeTruthy();
});

it('should have color dropdown', () => {
  expect(colorDropdown.isDisplayed()).toBeTruthy();
});

it('should have title and color dropdown', () => {
  expect(vehicleTitle.getText()).toBeTruthy();
  expect(colorDropdown.isDisplayed()).toBeTruthy();
});

结果：

  ✓ should render vehicle title
  ✓ should have color dropdown
  ✗ sould have title and color dropdown

我的量角器配置：

// Protractor configuration file, see link for more information
// https://github.com/angular/protractor/blob/master/lib/config.ts

/*global jasmine */
const { SpecReporter } = require('jasmine-spec-reporter');
const HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter');
const reporter = new HtmlScreenshotReporter({
  dest: 'e2e/reporter/screenshots',
  filename: 'protractor-report.html',
  userCss: '../style.css',
  ignoreSkippedSpecs: true,
  reportOnlyFailedSpecs: false,
  captureOnlyFailedSpecs: true
});

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/*.e2e-spec.ts'
  ],
  capabilities: {
    browserName: 'chrome',
    chromeOptions: {
      args: [
        'incognito',
        'disable-extensions'
      ]
    }
  },
  directConnect: true,
  baseUrl: 'http://127.0.0.1:9000/',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  },
  // Setup the report before any tests start
  beforeLaunch: function() {
    return new Promise(function(resolve){
      reporter.beforeLaunch(resolve);
    });
  },
  afterLaunch: function(exitCode) {
    return new Promise(function(resolve){
      reporter.afterLaunch(resolve.bind(this, exitCode));
    });
  },
  onPrepare() {
    require('ts-node').register({
      project: 'e2e'
    });
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
    jasmine.getEnv().addReporter(reporter);
  }
};

我已经尝试增加量角器配置中可用的多个超时，并使用browser.sleep（n），browser.ignoreSynchronization = true和/或browser.waitForAngularEnabled（false）但没有任何效果..

提前感谢您的时间！

Answer 1

确定Angular环境中有$超时。 要求前端开发人员查看$timeout并将其替换为$ interval。

如果您的AngularJS应用程序不断轮询$ timeout或$ http，Protractor将无限期地等待并超时。您应该将$ interval用于连续轮询的任何内容（在Angular 1.2rc3中引入）。

Answer 2

您需要使用更高的值来增加allScriptsTimeout。在你的情况下，量角器等了11秒，它就抛出了一个错误。
