问题
If i need to run same one method with two different browser at the same time then how will i implement it? For example:
public class AppTest2{
@parameters("browser")
@Test(dataProvider="loginData")
public void login(String userName , String password, String param){
if(param.equals("firefox"){
//do something
}
if(param.equals("chrome"){
//do something else
}
}
}
in my testng.xml file contains:
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name ="My sutie" parallel = "methods", thread-count="5">
<parameter name="browser" value="firefox"/>
<test name ="My Test1">
<classes>
<class name="mq.demo.selenium.AppTest2"/>
</classes>
</test>
</suite>
So my target is to run the login method in two different browser at the same time using two different thread.
Can anyone Help?
Thanks

You can consider something like the below as a possible solution
package com.rationaleemotions.stackoverflow;
import org.testng.IAlterSuiteListener;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import org.testng.collections.Maps;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlSuite;
import org.testng.xml.XmlTest;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
public class MultiBrowserSample {
@Test
@Parameters("browser")
public void testMethod(String browser) {
System.err.println("Browser : " + browser + " on Thread [" + Thread.currentThread().getId() + "]");
}
public static class MySuiteAlterer implements IAlterSuiteListener {
@Override
public void alter(List<XmlSuite> suites) {
XmlSuite suite = suites.get(0);
//Check if there was a parameter named "browserFlavors" defined at the suite
String browserFlavors = suite.getParameter("browserFlavors");
if (browserFlavors == null || browserFlavors.trim().isEmpty()) {
//If no such parameter was found, then Try querying the JVM arguments to see if it contains
//value for it. Just to ensure we don't end up in a situation wherein there's no JVM also provided
//Lets add a default value for the JVM argument which in our case is "firefox"
browserFlavors = System.getProperty("browserFlavors", "firefox");
}
String[] browsers = browserFlavors.split(",");
List<XmlTest> xmlTests = new ArrayList<>();
for (String browser : browsers) {
XmlTest xmlTest = new XmlTest(suite);
xmlTest.setName(browser + "_test");
Map<String, String> parameters = Maps.newHashMap();
parameters.put("browser", browser);
xmlTest.setParameters(parameters);
XmlClass xmlClass = new XmlClass();
xmlClass.setName(MultiBrowserSample.class.getCanonicalName());
xmlTest.getClasses().add(xmlClass);
xmlTests.add(xmlTest);
}
suite.setTests(xmlTests);
}
}
}
The suite xml file can look like below
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="1265_Suite" parallel="tests" verbose="2">
<listeners>
<listener class-name="com.rationaleemotions.stackoverflow.MultiBrowserSample$MySuiteAlterer"/>
</listeners>
<!--
If the below line gets uncommented, then 3 <test> tags will be formed one for each browser flavor.
Since its now commented, you will have to provide a value for it via the JVM argument
-DbrowserFlavors=firefox,chrome,ie (or) the system will default to just working with firefox
-->
<!--<parameter name="browserFlavors" value="firefox,chrome,ie"/>-->
</suite>
So as you can see, here we are resorting to using a TestNG listener called IAlterSuiteListener
implementation which is going to help us construct the <test>
tags in the suite xml file dynamically and the number of <test>
tags in the suite xml file will be directly equal to the number of browsers specified either via the suite level parameter browserFlavors
(or) via the JVM argument -DbrowserFlavors
The output would be as below
