Selenium+Java显示等待和隐式等待

描述：用来操作界面上的等待时间，显示等待是等待某一条件满足，条件满足后进行后面的操作；隐式等待是给出一个等待时间，在时间到达之前若满足条件，则立即执行后续操作。

public class TestSelenium {

    WebDriver webDriver = null;

    @Before
    public void Setup(){
        File chromeDriverPath = new File("D:\\Selenium\\webdriver\\chromedriver.exe");
        System.setProperty("webdriver.chrome.driver", chromeDriverPath.getAbsolutePath());
        webDriver = new ChromeDriver();
    }
　　@Test
    public void testWait(){
        webDriver.get("http://www.baidu.com");

        WebElement webElement = webDriver.findElement(By.name("wd"));
        webElement.sendKeys("Selenium 2");
        webElement.submit();

        //1. 显示等待
        (new WebDriverWait(webDriver, 10)).until(new ExpectedCondition<Boolean>() {

            @Override
            public Boolean apply(WebDriver driver) {
                // TODO Auto-generated method stub
                return driver.getTitle().toLowerCase().startsWith("selenium");
            }

        });

        System.out.println("Page title is:"+webDriver.getTitle());

        webDriver.navigate().back();

        //2. 隐式等待
        webDriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        webDriver.findElement(By.xpath("//*[@id=\"u1\"]/a[1]")).click();

        webDriver.quit();
    }
}
