How to Efficiently Track and Iterate Through Selenium WindowHandles in Unpredictable Order?

The best practice of high -efficiency management of the selenium window and label

Introduction

When using the SELENIUM Webdriver for the UI test of the Internet Explorer 11, managing multiple labels and windows may be tricky. In order to effectively track them, the use of attributes is very important. However, when the expected order of the window handle is unstable, common problems occur. This article will introduce how to solve this problem and explore a more effective solution.

Randomness of the order of the window handle WindowHandles

In contrast to expectations, the order of is not stable. Webdriver implements iteration in any way without any guarantee for insertion order. This may make it difficult to effectively manage multiple windows and switch between them.

Manage the dictionary

WindowHandles

A solution is to create a dictionary, using

GUID as the key, and the corresponding page type as a value. This method ensures correct switching between the windows. However, it requires additional maintenance, especially when closing the window. Introduction to webdriverwait

WindowHandle A better method is to use

. This allows you to pause before collecting . Collecting them by collecting new label/window every time you can create a series of serial lists and use

to switch to the required window. Example implementation

WebDriverWait The following is an example implementation in Java: WindowHandles switchTo().window(newly_opened)

This code automatically opens multiple tabs, wait for them to load, and then switch to the corresponding window with an orderly

list. Conclusion

Although it is feasible to use the dictionary window management, the introduction of

    public static void main(String[] args) {

        WebDriver driver = new InternetExplorerDriver();

        String first_tab = driver.getWindowHandle();

        ((JavascriptExecutor) driver).executeScript("window.open('http://facebook.com/');");

        WebDriverWait wait = new WebDriverWait(driver, 5);
        wait.until(ExpectedConditions.numberOfWindowsToBe(2));

        Set<String> s1 = driver.getWindowHandles();
        Iterator<String> i1 = s1.iterator();
        String next_tab;
        while (i1.hasNext()) {
            next_tab = i1.next();
            if (!first_tab.equalsIgnoreCase(next_tab)) {
                driver.switchTo().window(next_tab);
            }
        }
    }
}</code>
