How to do parameterization in Selenium Webdriver?
提问by Tufan
How to do parameterization in Selenium 2 (WebDriver)? I use Eclipse with maven plugins and I have no previous experience on Selenium Webdriver. When I google for it then every thing shows about testNG and JUnit. Is there any method through which we can parameterized the Webdriver?

I am going to make assumption - you would like to pass some parameter to the Webdriver. That can be done via two ways:
我要做一个假设——你想将一些参数传递给 Webdriver。这可以通过两种方式完成：
Make class which extends Webdriver and make its constructor to have the parameter which you need to pass. However, this is the hardway, because you have to implement/override all (needed) functions from webdriver:
public class MyWebdriver extends Webdriver{ private String theParameter; public MyWebdriver(String parameter){ //... initialize the Webdriver //store the parameter theParameter = parameter }Make your own wrapper, which will contain instance off WebDriver. That is easy(-ier). For example: In my own tests, I need to tell the Webdriver which environment I am testing. So I created my own class for the Environment:
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; } }
创建扩展 Webdriver 的类并使其构造函数具有您需要传递的参数。但是，这是困难的方法，因为您必须从 webdriver 实现/覆盖所有（需要的）功能：
public class MyWebdriver extends Webdriver{ private String theParameter; public MyWebdriver(String parameter){ //... initialize the Webdriver //store the parameter theParameter = parameter }制作您自己的包装器，其中将包含 WebDriver 的实例。这很容易（-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; } }
and then I have my own WebDriver wrapper, where I initialize it like this:
然后我有我自己的 WebDriver 包装器，在那里我像这样初始化它：
public class TestUI{
private Webdriver driver;
private Environment env;
public TestUI(Environment e){
this.env = e;
driver = new FirefoxDriver;
driver.get(env.getBaseUrl());
}
}
And in the test:
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
}
}

My suggestion would be to try to use a testing framework (TestNG or Junit) which gives many more features than just parametrization. Probably a little effort in setting up the framework in the beginning will save a lot of effort when your test code grows.
我的建议是尝试使用一个测试框架（TestNG 或 Junit），它提供了比参数化更多的功能。可能一开始就设置框架的一点努力，当您的测试代码增长时会节省很多精力。

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();
}
}
and to pass the values from the properties file use property(); in main class. and execute
并从属性文件使用 property() 传递值；在主班。并执行

@Parameters({ "first-name" })
@Test
public void testSingleString(String firstName) {
System.out.println("Invoked testString " + firstName);
assert "Cedric".equals(firstName);
}
In this code, we specify that the parameter firstName of your Java method should receive the value of the XML parameter called first-name. This XML parameter is defined in testng.xml: <-- ... -->
在此代码中，我们指定 Java 方法的参数 firstName 应接收名为 first-name 的 XML 参数的值。这个 XML 参数在 testng.xml 中定义：<-- ... -->

/* 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
