Webdriver JS测试期间无法切换窗口

Question

在 Selenium Webdriver 使用 Jasmine JS 进行测试期间，我无法切换窗口。

跑步者：量角器 JS

平台：Node.JS 上的 Selenium Webdriver

代码框架：Jasmine JS

代码如下，请注意第二个代码块：

describe('payments', function() {

    // beforeEach(function() {
    //             browser.ignoreSynchronization = true;
    //         });

    // afterEach(function(){
    //     browser.ignoreSynchronization = false;
    //  });

    this.selectWindow = function (index) {

      browser.driver.wait(function() {
        return browser.driver.getAllWindowHandles().then(function (handles) {

            if(handles.length > index) {
              return true;
            }
          });
      });
      return browser.driver.getAllWindowHandles().then(function (handles) {
        return browser.driver.switchTo().window(handles[index]);
      });
    };


  it('Client LiveSite - Payments - Perform a payment', function() {

    browser.driver.get("https://www.vcita.com/v/bungee/home");
    browser.driver.sleep(5000);
    element(by.xpath("//div[@class='actions-row']//a[.='Make Payment']")).click();
    browser.driver.sleep(2000);
    element(by.name("amount")).sendKeys("5");
    // element(by.model("payou_request.payou.amount")).sendKeys("5");
    element(by.name("pay_for")).sendKeys("Mister Bungee");
    element(by.name("notes")).sendKeys("Please approve my payments. Thanks a lot, Dr. Kugler. +972545453435");
    element(by.name("email")).sendKeys("idanvcita@gmail.com");
    element(by.name("first_name")).click();
    browser.driver.sleep(5000);
    element(by.css("button.btn.ng-binding")).click();
      });

  it('paypal', function() {
    browser.ignoreSynchronization = false;
        browser.driver.getAllWindowHandles().then(function (handles) {
        browser.driver.switchTo().window(handles[1]);
    });
    element(by.id("pay_button")).click();
    browser.driver.sleep(10000);


  // it('Client LiveSite - Payments - PayPal Lightbox', function() {

    // handlePromise.then(function (handles) {
    //   var popUpHandle = handles[1];
    //   var handle = driver.switchTo().window(popUpHandle).getWindowHandle();
    //   expect (handle).toEqual(popUpHandle);
    //     });

    //expect (element(by.text("Your payment summary")).isPresent()).toBe(true);
    element(by.id("loadLogin")).click();
    browser.driver.sleep(1000);
    element(by.id("login_email")).sendKeys("email");
    element(by.id("login_password")).sendKeys("pass");
    element(by.id("submitLogin")).click();
    element(by.id("login_password")).click();
    element(by.id("submit.x")).click();
  });

});

来自 Node.JS 的错误：

这是相关的css代码：

Answer 1

UnknownError: null value in entry: name=null

此错误表示您正试图切换到具有undefined 名称或句柄的窗口。也就是说，此时窗口没有打开。

此外，您提供的代码存在多个问题：

• 您需要将两个 it 块组合成一个块，因为它们使用不同的浏览器窗口
• 打开paypal支付页面的逻辑有问题-需要依次点击Continue和Continue to payment按钮
• 您需要解析getAllWindowHandles() 并继续在then 功能块内工作
• 将explicit waits 与"Expected Conditions" 一起使用，而不是使用sleep()，这会使您的测试不可靠、缓慢且脆弱
• 无需使用browser.driver，使用browser（您正在测试角度页面）
• 在打开新的非角度窗口之前将ignoreSynchronization设置为true，在afterEach()(Non-angular page opened after a click)中将其设置回false

适合我的固定代码：

describe('payments', function () {

    afterEach(function () {
        browser.ignoreSynchronization = false;
    });

    it('Client LiveSite - Payments - Perform a payment', function () {
        var EC = protractor.ExpectedConditions;

        browser.get("https://www.vcita.com/v/bungee/home");

        var makePayment = element(by.xpath("//div[@class='actions-row']//a[.='Make Payment']"));
        browser.wait(EC.visibilityOf(makePayment), 5000);
        makePayment.click();

        var amount = element(by.name("amount"));
        browser.wait(EC.visibilityOf(amount), 5000);
        amount.sendKeys("5");

        element(by.name("pay_for")).sendKeys("Mister Bungee");
        element(by.name("notes")).sendKeys("Please approve my payments. Thanks a lot, Dr. Kugler. +972545453435");
        element(by.name("email")).sendKeys("idanvcita@gmail.com");
        element(by.name("first_name")).click();

        browser.sleep(5000);

        // Click "Continue"
        element(by.xpath("//button[. = 'Continue']")).click();

        // Click "Continue to Payment"
        element(by.xpath("//button[. = 'Continue to Payment']")).click();

        browser.ignoreSynchronization = true;
        browser.getAllWindowHandles().then(function (handles) {
            browser.switchTo().window(handles[1]);

            var loadLogin = element(by.id("loadLogin"));
            browser.wait(EC.visibilityOf(loadLogin), 15000);

            loadLogin.click();

            // TODO: continue with payment
        });
    });

});

初步答案：

括号未正确分组。替换：

expect (element(by.text("Your payment summary"))).isPresent().toBe(true);

with（注意isPresent()之后的结束)）：

expect (element(by.text("Your payment summary")).isPresent()).toBe(true);

此外，您还有一个额外的不带参数的 findElement 调用，您需要将其删除：

browser.driver.findElement();
