Question

如何在Selenium 2（WebDriver）中进行参数化？我使用Eclipse和maven插件，我以前没有使用Selenium Webdriver。当我谷歌为它，然后每件事显示testNG和JUnit。我们可以通过哪种方法参数化Webdriver吗？

Answer 1

我要做出假设 - 你想将一些参数传递给Webdriver。这可以通过两种方式完成：

创建扩展Webdriver并使其构造函数具有您需要传递的参数的类。但是，这是 hard 方式，因为你必须从webdriver实现/覆盖所有（需要的）函数：

public class MyWebdriver extends Webdriver{
      private String theParameter;

     public MyWebdriver(String parameter){
       //... initialize the Webdriver

       //store the parameter
       theParameter = parameter
}

制作自己的包装器，它将包含WebDriver的实例。那是容易（ - ier）。例如：在我自己的测试中，我需要告诉Webdriver我正在测试哪个环境。所以我为环境创建了自己的类：

public class Environment{
  private String baseUrl;
  public enum NameOfEnvironment {DEV, ACC}
  private NameOfEnvironment environment;

  public Environment(NameOfEnvironment envName){
     environment = envName;
  }

  public String getBaseUrl(){
      switch (environment){
         case DEV: baseUrl = "https://10.10.11.12:9080/test/";
                   break;
         case ACC: baseUrl = "https://acceptance.our-official-site.com";
                   break;
      }
    return baseUrl;
  }
 }

然后我有自己的WebDriver包装器，我在这里初始化它：

public class TestUI{
      private Webdriver driver;
      private Environment env;

   public TestUI(Environment e){
       this.env = e;
       driver = new FirefoxDriver;
       driver.get(env.getBaseUrl());
   }
}

在测试中：

 public class TestCases{

   public static final Environment USED_ENVIRONMENT = new Environment(Environment.NameOfEnvironment.ACC);

 @Test
 public void testSomething(){
    testUI test = new testUI(USED_ENVIRONMENT);
    //.. further steps
 }
 }

我的建议是尝试使用测试框架（TestNG或Junit），它提供了比参数化更多的功能。在测试代码增长时，在开始时设置框架可能需要花费很多精力。

Answer 3

public void property(){
    try {

        File file = new File("login.properties");
        FileInputStream fileInput = new FileInputStream(file);
        Properties properties = new Properties();
        properties.load(fileInput);
        fileInput.close();

        Enumeration enuKeys = properties.keys();
        while (enuKeys.hasMoreElements()) {
            String key = (String) enuKeys.nextElement();
            String value = properties.getProperty(key);
            driver.findElement(By.id(key)).sendKeys(value);
            System.out.println(key + ": " + value);
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

并传递属性文件中的值使用property（）;在主要班级。并执行

Answer 4

@Parameters({ "first-name" })
@Test
public void testSingleString(String firstName) {
  System.out.println("Invoked testString " + firstName);
  assert "Cedric".equals(firstName);
}

在此代码中，我们指定Java方法的参数firstName应该接收名为first-name的XML参数的值。此XML参数在testng.xml中定义：＆lt; - ... - ＆gt;

我在这里提供一个可能有用的测试用例

 package pac1;
 import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.Wait;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
  import javax.xml.parsers.DocumentBuilderFactory;
 import org.w3c.dom.*;

public class test extends sut  {
static WebDriver driver;
static Wait<WebDriver> wait;
  public static boolean run(WebDriver driverArg, Wait<WebDriver> waitArg)
{
    driver = driverArg;
    wait = waitArg;
   // Run all the methods and return false if any fails
    return (test1() );
                  } 
   private static boolean test1()
   {



  driver.get("https://accounts.google.com");

    try {
        File file = new File("emaildata.xml"); //file location should be specified correctly put your xml in the same folder of the source code.
        // Prepare XML
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document document = db.parse(file);
        document.getDocumentElement().normalize();
        NodeList emailNodeElementList = document.getElementsByTagName("test");//test is the name of the child tag 
        for(int j=0;j<emailNodeElementList.getLength(); j++)//loop for the multiple data
    {
       String client = "The username or password you entered is incorrect. ?";
        Element emailNodeElement = (Element)emailNodeElementList.item(j);
        NodeList details = emailNodeElement.getChildNodes();
        String emailAddress=((Node) details.item(0)).getNodeValue();
        System.out.println("email :" + emailAddress);//it just prints which email is going to be parsed
        WebElement element = driver.findElement(By.cssSelector("body"));
            boolean feedBack = driver.findElement(By.cssSelector("body")).getText().contains(client);
            boolean feedbackVisible = element.isDisplayed();


    WebElement e1 = driver.findElement(By.id("Email"));//getting the location from the web
    e1.sendKeys(emailAddress);//sending keys to the server
    WebElement e3 = driver.findElement(By.id("signIn"));
    e3.click();


    if(feedBack==true){
        System.out.println(client+ "is present");
        if(feedbackVisible==true){
            System.out.println(client+ "is visible");
        }
        else{
            System.out.println(client+ "is not visible");
        }

    }
    else{
        System.out.println(client+ "is not present");

    }
    }
  }
 catch (Exception e) {e.printStackTrace();}

  return true;
  }}

您可以使用Apache或Jexcel的POI软件。

请查看下面的这些链接，它可能对您有帮助;

对于POI

和JExcel http://www.youtube.com/watch?v=yOGGdv8eT80

我希望它可以帮助你。我也不是专业人士，但在尝试学习参数化时，我用Google搜索并找到了这些链接。

Answer 7

/* You can pass parameters by creating two classes.
The first class, which you can call Main Class, will be public static void.
It will contain code such as:
*/
WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.com");
Parameters id = new Parameters();   //this is referring to second class
driver.findElement(By.name("q")).sendKeys(id.x);
//****************************************************************
//this is the second class [separate page] - here you can declare int or string varibale as public [so you can share them with other class while defining them]  - 
//when you make this class - don't need to add public static void

public String x = "username"
//if you look at the first page, I'm passing this string in the main script

public class ReadExcel {
       public String readData (String strSheetName, int strRowNo, int strCellNo) throws Exception {

              FileInputStream fis = new FileInputStream("D:\\Selenium\\TestData.xlsx");
              Workbook wb = WorkbookFactory.create(fis);
              Sheet sh = wb.getSheet(strSheetName);
              Row rw = sh.getRow(strRowNo);
              String val = rw.getCell(strCellNo).getStringCellValue();

              return val;

              }
