javascript - Protractor - 打开弹出窗口时，它不会等待此窗口内的所有元素

Question

我试图让我的测试稳定，但有时它没有等待集成弹出窗口中的所有元素并且失败了。

这个测试用例有点复杂，因为它在另一个 if 语句中包含 if 语句，以便为 FireFox 和 Chrome 运行相关代码(它们对弹出窗口有不同的处理)，

第二个条件是用户已经登录并且不应该点击 id="loadlogin"的元素。

被测元素的CSS:

<input type="submit" value="Log in to your PayPal account" id="loadLogin" name="login_button" class="parentSubmit">

测试用例-代码:

 it('Exisiting Client LiveSite - Payments - Continue To Payment', function () {
    element(by.binding("client_zone.payous.new.continue")).click();
    waitPageToLoad();
});

it('Exisiting Client LiveSite - Payments - Perform a payment by PayPal', function () {
    var loadLogin = element(by.id("loadLogin"));

    browser.wait(EC.visibilityOf(element(by.binding("buttonText"))), 15000);
    element(by.binding("buttonText")).click();

  if (browser === 'firefox') {
        browser.getAllWindowHandles().then(function (handles) {      
            browser.switchTo().window(handles[handles.length - 1]);

            element.all(by.id('loadLogin')).then(function(){

            // expect(browser.driver.getCurrentUrl()).toContain('www.paypal.com');
              if (loadLogin) {
                    loadLogin.click();
                    browser.driver.sleep(3000);
                                             element(by.id("login_email")).sendKeys("username");
                     element(by.id("login_password")).sendKeys("password");
                    browser.driver.sleep(1000);
                    element(by.id("submitLogin")).click();
                    browser.driver.sleep(5000);
                    element(by.id("submit.x")).click();
                    browser.driver.sleep(10000);
                    console.log("-=-=- first condition - FF -=-=-");
                } else {
                     element(by.id("login_email")).clear();
                     browser.driver.sleep(1000);
                                              element(by.id("login_email")).sendKeys("username");
                     element(by.id("login_password")).sendKeys("password");
                     browser.driver.sleep(1000);
                     element(by.id("submitLogin")).click();
                     browser.driver.sleep(10000);
                     element(by.id("submit.x")).click();
                     browser.driver.sleep(10000);
                     console.log("-=-=- second condition - FF -=-=-")
                }
            });

            browser.getAllWindowHandles().then(function (handles) {
                browser.switchTo().window(handles[0]);
            });
        });
    }

    else {
        browser.getAllWindowHandles().then(function (handles) {      
            browser.switchTo().window(handles[1]);

             element.all(by.id('loadLogin')).then(function(){
            // expect(browser.driver.getCurrentUrl()).toContain('www.paypal.com');
              if (loadLogin) {
                    loadLogin.click();
                    browser.driver.sleep(3000);
                                             element(by.id("login_email")).sendKeys("username");

Answer 1

我认为问题可能在于您没有切换到正确的窗口，因为窗口的顺序可能是动态的。这是我的建议，

1. Before clicking on the loadLogin button I would save the main window handle. After all window handles are nothing but an array of hash
2. When you click on the login, just switch to the window that is NOT main window. This way you can perform login without having to blindly switching to a window. I think this will also simplify your firefox vs chrome logic

像这样的伪代码，

var mainWindow;
browser.getAllWindowHandles().then(
    function(handles) {
        mainWindow = handles[0]; //at this point there should be only 1 window
    }
);

browser.getAllWindowHandles().then(function (handles) {      
   handles.forEach(function(handle) {
     if (handle !== mainWindow) {
        browser.switchTo().window(handle);
        element.all(by.id('loadLogin')).then(function(){ 
            //do more stuff
        }
     }
   }
});
