如何解决量角器测试无限期挂起的问题?

How can I resolve an issue where a Protractor test hangs indefinitely?

我遇到了一个问题，我以前运行过一个测试用例，我知道它正在工作，现在在执行时无限期地卡住了。每次测试单击一个特定的元素时都会发生这种情况。测试只是挂起，无法继续执行脚本。除了超时错误外，不发生任何错误。当我运行测试时，我得到常规提示:

[11:58:20] I/direct - Using ChromeDriver directly...
[11:58:20] I/launcher - Running 1 instances of WebDriver
Started
A Jasmine spec timed out. Resetting the Webdriver Control Flow.

Failures:
1) clicks menu buttons
Message:
Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.
Stack:

[12:48:47] I/launcher - overall: 1 failed spec(s)
[12:48:47] E/launcher - Process exited with error code 1

然后它就挂在那里，直到达到我设置的超时。以下是我正在使用的配置和部分测试脚本的副本。

config.js 

 exports.config = {
    seleniumAddress: 'http://localhost:4444/wd/hub',
    directConnect: true,
    //getPageTimeout: timeout_in_millis
    // Capabilities to be passed to the webdriver instance.
    capabilities: {
    'browserName': 'chrome'
    //'browserName': 'firefox'
    },
    //suites:{},
    specs: ['basic_testing.js'],
    allScriptsTimeout: 3000000,
   //framework: 'jasmine2',
    onPrepare: function() { 
                browser.driver.manage().window().maximize();
    var jasmineReporters = require('jasmine-reporters');
    jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
        consolidateAll: true,
        savePath: 'testresults',
        filePrefix: new Date().toJSON().substring(0,10).replace(/-/g , "")  + '_xmloutput'
    }))
},
    //Options to be passed to Jasmine.
    jasmineNodeOpts: {
       defaultTimeoutInterval: 3000000
    }
};

basic_testing.js 

describe('menu page', function()
{
    it('clicks menu buttons', function()
    {
        element(by.id("nav-group-ServiceOrders")).click();
        element(by.id("nav-item-Dashboard")).click();
        //This element is clicked but then the test hangs here
        element(by.id("nav-item-OrdersConsole")).click();
        element(by.id("nav-item-PersonnelConsole")).click();
        element(by.id("nav-item-PriorityPoints")).click();
    });
});

如果您已经探索了超时，并且仍然面临问题，那么如果点击第一个元素后的结果页面加载了第二个要点击的元素，但需要花时间加载页面中的所有元素，然后停止进一步加载元素并继续点击第二个元素，则使用browser.executeScript('window.stop();');。您的代码将如下所示。

var EC = protractor.ExpectedConditions;
1stElement.click();
browser.wait(EC.presenceOf(2ndElement), 5000);
browser.wait(EC.visibilityOf(2ndElement), 5000);
browser.executeScript('window.stop();');
2ndElement.click();
