注意：只有满足显式等待要求，代码才会向后执行，当显式等待条件未满足时，在设定的最大显式等待时间区间内，会停在当前代码位置进行等待，直到设定的条件被满足，

才能继续执行后续的测试逻辑。如果超过设定的最大显式等待时间区间，程序会抛出异常，测试用例被认为执行失败。

driver.manage().window().maximize();new WebDriverWait(driver,5).until(ExpectedConditions.titleIs("百度一下，你就知道")); //标题是不是“百度一下，你就知道”

System.out.println(new WebDriverWait(driver,5).until(ExpectedConditions.titleIs("百度一下，你就知道")));new WebDriverWait(driver,5).until(ExpectedConditions.titleContains("百度一下")); //标题是不是包含“百度一下”

System.out.println(new WebDriverWait(driver,5).until(ExpectedConditions.titleContains("百度一下")));
