How can I externalise my selenium setup in order to make my selenium tests configurable - selenium-webdriver

Question

I would like to externalise my selenium tests setting in order to make them more configurable.
I would like to externalise my testURL and my node URLS.
Here is my code :
public void setup () throws MalformedURLException
{ //the URL of the application to be tested
TestURL = "http://frstmwarwebsrv2.orsyptst.com:9000";
//Hub URL
BaseURL = "http://10.2.128.126";
//Node1 URL
winURL = "http://10.2.128.120:5556/wd/hub";
//Node2 URL
androidURL ="http://10.2.128.120:5555/wd/hub";
At the moment I have added this setup function in every test I would like to have it in an XML file for an example in order to make it configurable, any suggestions?
Thanks
Thanks for your help
Update :
Here is what i did so far :
Added a config.properties file with this content :
# This is my test.properties file
AppURL = http://************
HubURL= http://*****************
WinURL= http://*********/wd/hub
AndroidURL =
iOSURL
And created a classe to read properties :
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Properties;
public class ReadPropertiesFile {
public static void main(String[] args) {
try {
File file = new File("config.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);
System.out.println(key + ": " + value);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
when running this i get this error :
java.io.FileNotFoundException: config.properties (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at ReadPropertiesFile.main(ReadPropertiesFile.java:15)
my properties file is under src folder

Answer 1

Two basic ways you could do this are:
Pass in JVM argument and access it using System.getProperty(...)
Externalize your configuration in to properties files, like here
I recently implemented the second one in my Selenium tests and can expand this answer to give more details if you need them.

Answer 2

In my tests, I resolved it that I created Java class called Environment to store information about given Environment:
Few snippets of code:
public enum NameOfEnvironment {
SYSTEMTEST, ACCEPTANCE
}
stores the Name of given Environment :)
public String getBaseUrl() {
switch (actualEnvironment) {
case SYSTEMTEST: {
baseUrl = getPrefix() + "172.23.32.251:9092/pages/index.html";
break;
}
will return me the URL to the environment. And on beginning of the test I have something like this:
public static final Environment USED_ENVIRONMENT = new Environment(Environment.NameOfEnvironment.SYSTEMTEST);
And later on I just call USED_ENVIRONMENT.getBaseUrl() which will return me the link which is being actual for current run
Btw, to fill in the blanks, here is the constructor f the class
public Environment(NameOfEnvironment env) {
this.actualEnvironment = env;
}
