Dear all I am using Selenium EventFiringWebDriver to record the called web driver methods. I recognised that I often get a "StaleReferenceException" while when I just use the HtmlUnitDriver alone I don't have the issue.
I also recognised that the call i.e. "click()" has been performed in the browser although the "StaleElementReferenceException" got thrown.
Has anybody an idea while the EventFiringWebDriver runs into such problems while using the HtmlUnitDriver or FirefoxDriver standalone not? Could it be that the WebElements get updated by the origin drivers at runtime while the wrapped WebElements of the EventFiringWebDriver not? Or should we raise this as a bug for the EventFiringWebDriver implementation?
Example code with EventFiringWebDriver - throws StaleElementReferenceException
HtmlUnitDriver driver = new HtmlUnitDriver();
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
ExtentReports extent = new ExtentReports ("report.html", true);
ExtentTest logger = extent.startTest("test");
EventFiringWebDriver eventDriver = new EventFiringWebDriver(driver);
eventDriver.register(new MyWebDriverEventListener(logger));
try {
WebElement element = null;
eventDriver.get("https://www.google.com");
element = eventDriver.findElement(By.xpath("//input[@type='text']"));
element.sendKeys("Test");
element.submit();
Thread.sleep(2000);
element = eventDriver.findElement(By.xpath("//div[@id='search']//a"));
String title = element.getText();
// HERE the StaleElementReferenceException get thrown ALTHOUGH the "click" event get processed by the browser, it loads already the page
try {
element.click();
} catch(StaleElementReferenceException ex) {
}
Thread.sleep(2000);
Assert.assertEquals(title, eventDriver.getTitle());
logger.log(LogStatus.PASS,"end","Test passed");
} catch(AssertionError error) {
logger.log(LogStatus.FAIL,"end","Test failed:" + error.getMessage());
throw error;
}
finally {
extent.endTest(logger);
extent.flush();
extent.close();
eventDriver.quit();
}
The same code - just using the HtmlUnitDriver directly, works without any problems
HtmlUnitDriver driver = new HtmlUnitDriver();
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
ExtentReports extent = new ExtentReports ("report.html", true);
ExtentTest logger = extent.startTest("test");
try {
WebElement element = null;
driver.get("https://www.google.com");
element = driver.findElement(By.xpath("//input[@type='text']"));
element.sendKeys("Test");
element.submit();
Thread.sleep(2000);
element = driver.findElement(By.xpath("//div[@id='search']//a"));
String title = element.getText();
element.click();
Thread.sleep(2000);
Assert.assertEquals(title, driver.getTitle());
logger.log(LogStatus.PASS,"end","Test passed");
} catch(AssertionError error) {
logger.log(LogStatus.FAIL,"end","Test failed:" + error.getMessage());
throw error;
}
finally {
extent.endTest(logger);
extent.flush();
extent.close();
driver.quit();
}
