error-handling - 哪一行导致此 Protractor 错误？

Question

Protractor 有没有办法在控制台日志中显示错误发生在哪一行？我只收到这种类型的消息:

Message:
    Failed: Cannot call method 'click' of undefined
  Stack:
    Error: Failed: Cannot call method 'click' of undefined
        at /usr/local/lib/node_modules/protractor/node_modules/jasminewd2/index.js:104:16
        at /usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/goog/base.js:1582:15
        at [object Object].webdriver.promise.ControlFlow.runInNewFrame_ (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/promise.js:1654:20)
        at notify (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/promise.js:465:12)

1 spec, 1 failure

很难弄清楚我是否有这么多的点击命令。我正在运行 Protractor 1.8.0。

这是我的 protractor.conf.js :

exports.config = {
  framework: 'jasmine2',

  seleniumAddress: 'http://11.111.1.11:4444/wd/hub',

  multiCapabilities: [{
    'browserName': 'chrome',
    'chromeOptions': {
        args: ['--test-type']
    }
  }],

  specs: ['./tests/my_test/*_spec.js'],

  onPrepare: function(){

      global.EC = protractor.ExpectedConditions;

      browser.manage().window().maximize();

      var jasmineReporters = require('jasmine-reporters');

      jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
        consolidateAll: true,
        filePrefix: 'tests_xmloutput',
        savePath: './test_results_report'
      }));
  },

  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000
  }
};

完整的错误消息是:

Failures:

  Message:

规范文件/测试的内容将是:

HeaderNavigationPartialPage.myAppButton.click();
LeftNavigationPartialPage.myAppToolsLink.ERROR-ON-PURPOSE.click();  
browser.wait(EC.elementToBeClickable(LeftNavigationPartialPage.myAppSearchLink), 10000);
LeftNavigationPartialPage.myAppSearchLink.click();

Answer 1

这是 jasminewd 的相关问题项目protractor在幕后使用:

Stack traces for Jasmine2 don't include asynchronous events

该问题现已修复，使用 jasmine升级到 >=2.3.1 .

你应该做的是 升级 protractor至 >=2.1.0 .

旧答案:

作为解决方法，请返回 jasmine 1.x :

exports.config = {
    framework: 'jasmine',

    ...
}
