Can't switch windows during testing by Webdriv

问题:

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

Runner: Protractor JS

Platform: Selenium Webdriver on Node.JS

Code framework: Jasmine JS

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. [phone]");
    element(by.name("email")).sendKeys("[e-mail]");
    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();
  });

});

This is the relevant css code:

UnknownError: null value in entry: name=null

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.

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

• 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)

Fixed code that works for me:

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. [phone]");
        element(by.name("email")).sendKeys("[e-mail]");
        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
        });
    });

});

Initial answer:

The parenthesis are not grouped correctly. Replace:

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

with (note the closing ) after isPresent()):

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

Also, you have an extra findElement call with no arguments, which you need to remove:

browser.driver.findElement();
