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

I can't switch windows during my testing by Selenium Webdriver using Jasmine JS.

跑步者:量角器 JS

平台:Node.JS 上的 Selenium Webdriver

Platform: Selenium Webdriver on Node.JS

代码框架:Jasmine JS

Code framework: Jasmine JS

代码如下，请注意第二个代码块:

The code is below, Please note the second code block:

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:

This is the relevant css code:

<title>Pay with a PayPal account - PayPal</title><meta name="description" content="PayPal is the safer, easier way to pay online without revealing your credit card number."><meta http-equiv="X-UA-Compatible" content="IE=9"><link media="screen" rel="stylesheet" type="text/css" href="https&#x3a;&#x2f;&#x2f;www&#x2e;paypalobjects&#x2e;com&#x2f;WEBSCR&#x2d;640&#x2d;20150318&#x2d;1/css/core/global.css"><link rel="stylesheet" type="text/css" href="https&#x3a;&#x2f;&#x2f;www&#x2e;paypalobjects&#x2e;com&#x2f;WEBSCR&#x2d;640&#x2d;20150318&#x2d;1/Merchant/css/AP/checkout.css">

推荐答案

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.

This error means you are trying to switch to a window with undefined name or handle. In other words, the window is not opened at the moment.

此外，您提供的代码存在多个问题:

Also, there are multiple issues with the code you've presented:

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
将显式等待与"预期条件" 而不是使用 sleep() 进行测试不可靠、缓慢且脆弱
无需使用browser.driver，使用browser(你正在测试一个角度页面)
在打开一个新的非角度窗口之前将 ignoreSynchronization 设置为 true，在 afterEach()<中将其设置回 false/code> (点击后打开的非角度页面)



you need to group two it blocks into single one since they use different browser windows
there is a problem in logic that opens the paypal payment page - you need to click Continue and Continue to payment buttons sequentually
you need to resolve the getAllWindowHandles() and continue working inside the then function block
use explicit waits with "Expected Conditions" instead of using sleep() that makes your test unreliable, slow and fragile
no need to use browser.driver, use browser (you are testing an angular page)
set ignoreSynchronization to true before opening a new non-angular window, set it back to false in afterEach() (Non-angular page opened after a click)

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:




Initial answer:
括号未正确分组.替换:
The parenthesis are not grouped correctly. Replace:
expect (element(by.text("Your payment summary"))).isPresent().toBe(true);

在isPresent()之后加上(注意结束的)):
with (note the closing ) after isPresent()):
expect (element(by.text("Your payment summary")).isPresent()).toBe(true);

另外，你有一个额外的 findElement 调用，没有参数，你需要删除它:
Also, you have an extra findElement call with no arguments, which you need to remove:
browser.driver.findElement();
