Hi Ambika,

For effective debugging in Selenium WebDriver, use explicit waits to handle synchronization issues, check for incorrect locators or URLs, and use tools like browser developer consoles for error insights.

Also , please refer to this blog for more info:

Hey Salman,

Thanks for the resource. It’s valuable, but debugging can always be hectic for developers and testers.

There is one more tip I would like to share that will help you in debugging.

Take Screenshots of Failure: Capturing screenshots of test failure can provide visual clues about what went wrong. This can help you quickly identify missing elements, incorrect page loads, or other UI problems.

Solution: Screenshot Capture:

File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenshot, new File("path/to/save/screenshot.png"));

Automate Screenshot on Failure: Integrate this into your test framework to automatically take screenshots of test failure.

@AfterMethod
public void takeScreenshotOnFailure(ITestResult result) {
    if (ITestResult.FAILURE == result.getStatus()) {
        File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        FileUtils.copyFile(screenshot, new File("path/to/save/screenshot.png"));
    }
}

Hey Ambikha,

Use Browser Developer Tools : Leverage the browser’s built-in developer tools to inspect elements, debug JavaScript errors, and monitor network traffic. This can help you understand why certain elements are not found or interactions fail.

Solution:

Inspect Elements: Right-click on the web element and select “Inspect” to open the developer tools. Check the element’s properties and ensure your locators are correct. Console Logs: Check for JavaScript errors in the “Console” tab of the developer tools. You can also capture these logs in your Selenium tests.

LogEntries logs = driver.manage().logs().get(LogType.BROWSER);
for (LogEntry log : logs) {
    System.out.println(log.getMessage());
}

Network Tab: The “Network” tab monitors network requests and responses. This can help identify issues related to AJAX calls or resource loading.
