Question

我正在使用量角器和茉莉花进行自动化测试。我正在注册页面上进行测试，代码如下：

               it('Verify Alert  message when New user registered itself for the first time',function() {
    FuncLib.ButtonClick('Close'); //Close the error message displayed in previous scenario
    Registration.Email.clear(); //Clear valid E-mail Id
    Registration.Password.clear(); //Clear Password
    Registration.ConfirmPassword.clear(); //Clear   Confirm Password 
    Registration.Firstname.clear(); //clear Firstname Password
    Registration.Lastname.clear(); //clear Lastname Password
    Registration.Phonenumber.clear(); //clear phonenumber
    browser.sleep(500);
    Registration.Email.sendKeys('Forfirmtestuser+user217@gmail.com'); //Enter valid E-mail Id
    Registration.Password.sendKeys('Hello1'); //Enter Password
    Registration.ConfirmPassword.sendKeys('Hello1'); //Enter wrong  Confirm Password 
    Registration.Firstname.sendKeys('candy'); //Enter Firstname Password
    Registration.Lastname.sendKeys('smith'); //Enter Lastname Password
    Registration.Phonenumber.sendKeys('9191919106'); //Enter phone number.
    expect(Registration.Checkbox.isPresent()).toBe(true); // Terms and condition checkbox should display
    Registration.Checkbox.click(); // select the Terms and condition checkbox
    Registration.Checkbox.click(); // select the Terms and condition checkbox
    browser.sleep(200);
        expect(Registration.RegisterButton.isPresent()).toBe(true);
        Registration.RegisterButton.click(); //click Register button
        browser.sleep(200);
            browser.driver.wait(function() {  // Wait for the current URL to change to Home page
                return browser.driver.getCurrentUrl().then(function(url) {
                    return (/home/).test(url);
                });
            });


            expect(browser.getCurrentUrl()).toEqual(Registration.HomeURL);
            console.log('When New user registered itself for the first time:');
                expect(Registration.AlertMsg.getText()).toEqual(Registration.msg6);
                Registration.AlertMsg.getText().then(function(text) {
                console.log(' When New user registered itself for the first time:');    //Jasmine expect statement : compare actual and expected value
                });
});

一切正常，直到这部分代码：

                  expect(Registration.RegisterButton.isPresent()).toBe(true);
    Registration.RegisterButton.click(); //click Register button
    browser.sleep(200);
        browser.driver.wait(function() {  // Wait for the current URL to change to Home page
            return browser.driver.getCurrentUrl().then(function(url) {
                return (/home/).test(url);
            });
        });


        expect(browser.getCurrentUrl()).toEqual(Registration.HomeURL);
        console.log('When New user registered itself for the first time:');
            expect(Registration.AlertMsg.getText()).toEqual(Registration.msg6);
            Registration.AlertMsg.getText().then(function(text) {
            console.log(' When New user registered itself for the first time:');    //Jasmine expect statement : compare actual and expected value
            });

这里我在最后的报告中得到了这个错误：错误：超时 - 在jasmine.DEFAULT_TIMEOUT_INTERVAL指定的超时内未调用异步回调

我真的不明白为什么。

Answer 1

首先是browser.sleep（200）;使用起来不是好事。等待元素加载总是好的。在量角器中，这可以使用then函数完成。检查下面的样本，这将给你和想法

element(by.xpath("xpath_locator")).click().then(function(){
  var list = element(by.id('id_locator'));
  var until = protractor.ExpectedConditions;
  browser.wait(until.presenceOf(list), 80000, 'Element taking too long to appear in the DOM');
});

你有没有尝试过：
1.增加配置文件中的默认超时？
2.增加睡眠时间？ 3.在睡眠中插入期望值？

expect(Registration.RegisterButton.isPresent()).toBe(true);
Registration.RegisterButton.click(); //click Register button
browser.sleep(2000).then(function() {  // Wait for the current URL to change to Home page
    browser.getCurrentUrl().then(function(url) {
        expect(url).toEqual(Registration.HomeURL);
        console.log('When New user registered itself for the first time:');
        expect(Registration.AlertMsg.getText()).toEqual(Registration.msg6);
        Registration.AlertMsg.getText().then(function(text) {
            console.log(' When New user registered itself for the first time:');    //Jasmine expect statement : compare actual and expected value
        });
    });
});

Answer 3

您可以使用 Jasmine 回调来断言异步行为。 Jasmine 测试提供了额外的参数作为回调参数。完成断言后，您可以调用回调 API。

示例：

it('should have a button element present', function(done) {
browser.get('http://juliemr.github.io/protractor-demo/');

var gobtn = element(by.id('gobutton'));

gobtn.isPresent().then( (result) => {
 expect(result).toBe(true);    
 done();
 });    
});

量角器测试时出现错误超时
