Selenium有哪些不同的等待类型?
隐式等待
这是Selenium中动态等待的一种,其语法为-
driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
明确等待
这是Selenium中动态等待的一种,其语法为-
WebDriverWait w = new WebDriverWait(driver,); w.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("<<xpath expression>>")));
流利的等待
这是Selenium中动态等待的一种,其语法为-
Wait<WebDriver> w = new FluentWait<WebDriver>(driver).withTimeout(Duration.ofSeconds(30)) .pollingEvery(Duration.ofSeconds(3)).ignoring(NoSuchElementException.class);
静态等待
这用于将执行暂停指定的时间。
示例
import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class ThreadWait { public static void main(String[] args) throws InterruptedException { long start = System.currentTimeMillis(); //暂停执行1秒 Thread.sleep(1000); long startaftersleep = System.currentTimeMillis(); System.out.println("Sleep time in ms = "+ startaftersleep - start); } }
