我在导航回测试网址时遇到错误（低于3行代码）。在这些行中使用的等待低于前3行代码。 堆栈跟踪粘贴在等待代码下面。
我在IE11中运行Selenium 2.45，在Win 7机器上使用Java。
driver.navigate().to(testURL);
if (!Utils.waitForElementToBeVisibleByLocator(driver,
driver.findElement(By.xpath("locator")))) {}
public static boolean waitForElementToBeVisibleByLocator(WebDriver driver,
By locator) {
boolean webElement = false;
try {
driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);
wait = new WebDriverWait(driver, 60).ignoring(NoSuchElementException.class, StaleElementReferenceException.class).pollingEvery(12,TimeUnit.SECONDS);
wait.until(ExpectedConditions.presenceOfElementLocated(locator));
Log.info(locator + " is visible");
webElement = true;
} catch (Exception e) {
Log.error(locator + " is not visible | " + new Object() {
}.getClass().toString() + " | method " + new Object() {
}.getClass().getEnclosingMethod().getName());
Log.debug(e.getMessage());
webElement = false;
} finally {
driver.manage().timeouts().implicitlyWait(Constants.implicitWaitTime, TimeUnit.SECONDS);
}
return webElement;
}
