量角器点击功能并不总是有效

Question

我是量角器的新手.我已经为第一个用户登录应用程序编写了一个角度测试,然后单击特定按钮来计算一个数字.有时它有效,有时不行!

这是代码:

describe('Protractor Demo App', function () {

    it('should login to app', function () {
        browser.get('http://localhost:8080/main');
        var userName = element(by.id('username'));
        var passWord = element(by.id('pwd'));
        var loginBtn = element(by.id('loginBtn'));
        userName.sendKeys('user');
        passWord.sendKeys('1');
        loginBtn.click();
        expect(browser.getCurrentUrl()).toEqual('http://localhost:8080/main/#/intro');
    });


   it('should calculate something', function () {
        browser.get('http://localhost:8080/main/#/something');
        var next = element(by.css('[ng-click="calculate()"]'));
        element(by.model('accountNo')).sendKeys('0293949223008');
        next.click();  
        expect(element(by.binding('result')).getText()).toEqual('55017000000029');
    });

    it('should show error for invalid input no', function () {
        browser.get('http://localhost:8080/main/#/something');
        var next = element(by.css('[ng-click="calculate()"]'));
        element(by.model('accountNo')).sendKeys('9999456123789');
        next.click();
        expect(element(by.css('[class="messageObject warning"]')).getText()).toEqual('message for invalid input');
    });
});

首先"它"总是有效,但第二和第三,有时是工作.碰巧只有一个人没有工作;

这是错误:

我不知道问题是什么.谁能帮我？提前致谢.

在执行单击操作之前,使用ExpectedConditions.isElementToBeClickable()方法实现browser.wait().你遵循如下:

   var EC = protractor.ExpectedConditions;

 it('should show error for invalid input no', function (){
    browser.get('http://localhost:8080/main/#/something');
    var next = element(by.css('[ng-click="calculate()"]'));
    element(by.model('accountNo')).sendKeys('9999456123789');

    browser.wait(EC.elementToBeClickable(next ), 10000,'Element not  
                                                  clickable');
    next.click();
    expect(element(by.css('[class="messageObject  
    warning"]')).getText()).toEqual('message for invalid input');
   });
