Question

 public static void clickOnElement(By element, String comment, WebDriver driver) {
    WebDriverWait wait = new WebDriverWait(driver, 120);
    wait.pollingEvery(1000, TimeUnit.MILLISECONDS);
    wait.ignoring(NoSuchElementException.class);
    wait.ignoring(StaleElementReferenceException.class);
    wait.until(ExpectedConditions.and(ExpectedConditions.visibilityOfAllElementsLocatedBy(element),
            ExpectedConditions.elementToBeClickable(element)));
    WebElement context = driver.findElement(element);
    wait.until(new ExpectedCondition<Boolean>() {
    @Override
        public Boolean apply(WebDriver driver) {
            return ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("complete");
        }
    });
    driver.manage().timeouts().pageLoadTimeout(120,TimeUnit.SECONDS);
    context.click();

Answer 1

问题似乎出在这段代码wait.toil(expectedconditions.and(expectedconditions.visibilityofAllelementsLocatedby(element)，expectedConditions.ElementTobeclickable(element))；

这两个条件都不能同时得到完全填充，在达到阈值时间限制后抛出超时异常。

解决方案：

wait.until(ExpectedConditions.visibilityOfAllElementsLocatedBy(element));
wait.until(ExpectedConditions.elementToBeClickable(element));

wait.until(ExpectedConditions.visibilityOfElementLocated(element));
