如何验证一个元素是否在 Selenium 中显示在屏幕上?
我们可以借助以下列出的方法帮助验证 Web 元素(如编辑框、复选框和单选按钮等)是否可见 −
isDisplayed()
此方法检查 Web 元素是否显示在屏幕上。
语法 −
Boolean result = driver.findElement(By.xpath("//span[text()=’Coding Ground’]")).isDispayed();
isSelected()
此方法检查静态下拉菜单中单选按钮、复选框和选项的状态。
语法 −
Boolean btnresult = driver.findElement(By.xpath("//xpath[contains(@class,’gsc-search-button’)]")).isSelected();
isEnabled()
语法 −
Boolean btnresult = driver.findElement(By.xpath("//xpath[contains(@class,’gsc-search-button’)]")).isEnabled();
此方法检查一个元素是否已启用。
示例
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class ElementStatus{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://tutorialspoint.com/tutor_connect/index.php"; // to verify if a static dropdown is selected with option isSelected() boolean drpdwnStatus = driver.findElement(By.xpath("//select[@name=’selType’]")) .isSelected(); // to verify if an element is present on page with isDisplayed() boolean editStatus = driver.findElement(By.xpath("//input[@id=’txtSearchText’]")) .isDisplayed(); // to verify if a button is enabled with isEnabled() boolean butnStatus = driver.findElement(By.xpath("//input[@id=’searchSubmit’]")) .isEnabled(); System.out.println("The button status is " + butnStatus); System.out.println ("The dropdown selected status is" + drpdwnStatus); System.out.println("The edit box display status is " + editStatus); driver.close(); } }
