WebDriver - 使用Java等待元素 [英] WebDriver - wait for element using Java

问题描述

我正在寻找类似于 waitForElementPresent 的东西来检查元素是否在我点击之前显示。我认为这可以通过 implicitWait 来完成，所以我使用了以下内容：

I'm looking for something similar to waitForElementPresent to check whether element is displayed before I click it. I thought this can be done by implicitWait, so I used the following:

driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

然后点击

driver.findElement(By.id(prop.getProperty(vName))).click();

不幸的是，有时它等待元素，有时候不等。我找了一会儿找到了这个解决方案：

Unfortunately, sometimes it waits for the element and sometimes not. I looked for a while and found this solution :

for (int second = 0;; second++) {
            Thread.sleep(sleepTime);
            if (second >= 10)
                fail("timeout : " + vName);
            try {
                if (driver.findElement(By.id(prop.getProperty(vName)))
                        .isDisplayed())
                    break;
            } catch (Exception e) {
                writeToExcel("data.xls", e.toString(),
                        parameters.currentTestRow, 46);
            }
        }
        driver.findElement(By.id(prop.getProperty(vName))).click();

它等待好了，但在超时之前它必须等待5次，50秒。有点多。所以我将隐式等待设置为1秒，直到现在一切似乎都很好。因为现在有些东西会在超时前等待10秒，但有些东西会在1秒后超时。

And it waited all right, but before timing out it had to wait 10 times 5, 50 seconds. A bit much. So I set the implicitly wait to 1sec and all seemed fine until now. Because now some things wait 10s before timeout but some other things time out after 1s.

如何覆盖代码中等待的元素/可见元素？任何提示都很明显。

How do you cover the waiting for element present/visible in your code? Any hint is appreciable.

推荐答案

这就是我在代码中的做法。

This is how I do it in my code.

WebDriverWait wait = new WebDriverWait(webDriver, timeoutInSeconds);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id<locator>));

或

wait.until(ExpectedConditions.elementToBeClickable(By.id<locator>));

准确无误。
