在找到元素并执行元素上的操作后找到元素找不到元素

Question

我正在使用量角器，并且出现一个奇怪的问题。我登录并执行一些测试并注销。一切工作正常。我需要重新登录才能使用其他用户标识执行相同的测试。第二次即使在用户名和密码输入到其各自的字段并且登录成功完成但进程退出而未执行剩余测试并且我收到错误消息。下面是我的代码和错误，我得到

代码片段：

ar testData = require('./Test Data/Users.json'); 

describe('SSUE Login', function() { 

    it('Verifies user access', function() { 


     browser.driver.get('https://url'); 
     browser.ignoreSynchronization = true; 
     element(by.id('userInput')).sendKeys(testData[1].username); 
     element(by.id('passwordInput')).sendKeys(testData[1].passwordField); 
     element(by.id('login-button')).click(); 
     browser.driver.sleep(9000); 
     browser.waitForAngular(); 

     element(by.css('.AtlanticIcon_header_logout')).getText().then(function(text){ 
     console.log('Login Successful '+text+' icon visible in UI'); 

     }); 
     if(element(by.xpath('//div[@class="walkme-custom-balloon-content-wrapper"]')).isPresent().then(function(){ 
       element(by.xpath('//div[@class="walkme-custom-balloon-content-wrapper"]/div[1]')).click(); 
     })); 

     browser.driver.sleep(2000); 
     } 
    }, 90000); 
}); 

下面是我的配置文件 通知我登录，并执行6测试。在最后的6个测试中'gridFilter.js'我有一个注销操作。接下来，我使用另一个用户ID再次登录，通过'login2.js'。用户成功loged中，但登录后的下一个测试不执行和浏览器反复加载自身，最后进程退出，并得到结果输出JSON，我也加入了结果到底

exports.config = { 
    seleniumAddress : 'http://localhost:4444/wd/hub', 
    specs    : ['login.js', 'userType.js', 'globalFilterOptions.js', 'languageTest.js', 'loadDatagrid.js', 'datagridicons.js', 'gridFilter.js', 'login2.js', 'userType.js', 'globalFilterOptions.js', 'languageTest.js', 'loadDatagrid.js', 'datagridicons.js', 'gridFilter.js', 'login3.js', 'userType.js', 'globalFilterOptions.js', 'languageTest.js', 'loadDatagrid.js', 'datagridicons.js', 'gridFilter.js', 'login4.js', 'userType.js', 'globalFilterOptions.js', 'languageTest.js', 'loadDatagrid.js', 'datagridicons.js', 'gridFilter.js', 'login5.js', 'userType.js', 'globalFilterOptions.js', 'languageTest.js', 'loadDatagrid.js', 'datagridicons.js', 'gridFilter.js', 'login6.js', 'userType.js', 'globalFilterOptions.js', 'languageTest.js', 'loadDatagrid.js', 'datagridicons.js', 'gridFilter.js'], 
    // Exclude files if needed 
    exclude: [], 


    baseUrl: 'http://localhost:8000', 
    rootElement: 'html', 

    framework   : 'jasmine2', 

    jasmineNodeOpts: { 
    showColors: true, 
    defaultTimeoutInterval: 30000 
    ,print: function() {} 
    }, 

    onPrepare: function() { 
    var SpecReporter = require('jasmine-spec-reporter'); 
    // add jasmine spec reporter 
    jasmine.getEnv().addReporter(new SpecReporter({displayStacktrace: true})); 
    }, 

    onPrepare: function() { 
    var JSONReporter = require('jasmine-json-test-reporter'); 
    jasmine.getEnv().addReporter(new JSONReporter({ 
     file: 'SSUE-Daily-Satus-Report.json', 
     beautify: true, 
     indentationLevel: 4 // used if beautify === true 
    })); 
}, 


    // An array of capability objects 
    multiCapabilities : [ 
    { 
     browserName : 'chrome' 

     // Add another set of specs for this browser only 
     // specs: [] 
    } 
    ] 
}; 

这里在测试结果，我正在转化为JSON

Answer 1

你可以在你的代码中添加browser.pause，看看说明你的浏览器中，你可能会发现，你仍然登录或用户名的输入没有按不存在（也许应用程序的工作流程会记住用户名）。这不能从你的代码或你的堆栈跟踪得出结论，而是尝试它。

这是我想尝试：

• 导航到登录页面
• 登录使用用户0
• 注销
• browser.pause和检查浏览器的状态

---

类似于：

describe('login and logout',() => { 
    beforeEach(() => { 
    // navigate to login page 
    }); 

    it('should be logged in user 0',() => { 
    element(by.id('userInput')).sendKeys(testData[0].username); 
    element(by.id('passwordInput')).sendKeys(testData[0].passwordField); 
    element(by.id('login-button')).click(); 

    // assertions about logging in 
    // process to log out 
    // assertions about logging out 
    }); 

    // this spec should not run but we'll leave it in. 
    it('should be logged in user 1',() => { 
    element(by.id('userInput')).sendKeys(testData[1].username); 
    element(by.id('passwordInput')).sendKeys(testData[1].passwordField); 
    element(by.id('login-button')).click(); 

    // assertions about logging in 
    // process to log out 
    // assertions about logging out 
    }); 

    afterEach(() => { 
    // stop here to see what's going on with your browser. 
    // in the window, navigate to your login page. possibly your 
    // username input does not exist for various reasons. maybe this 
    // is a bug. 
    browser.pause(); 
    }); 
});
