Testng opens only one browser for parallel config

I want to run multiple tests in chrome. i.e 2 tests parallel in 2 chrome. I do have a maven project defined by the POM (testing.xml):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="mytestsuite" parallel="tests" >
<test name="case1">
<classes>
<class name="Testcases.hello1Test"></class>
</classes>
</test>
<test name="case2">
<classes>
<class name="Testcases.hello2.Test"></class>
</classes>
</test>
</suite>
Code to invoke browse is within my baseTest :
public hello1Page1 hellopage1;
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setJavascriptEnabled(true);
cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
cap.setCapability(ChromeOptions.CAPABILITY, options);
chromePath = System.getProperty("user.dir") + prop.getProperty("driverrPath");
System.setProperty("webdriver.chrome.driver", chromePath);
driver = new ChromeDriver(options);
driver.get(Prop.getProperty("URL"));
hellopage1 = PageFactory.initElements(driver, helloPage1.class);
This is page class :
public class hello1Page extends BaseTest {
WebDriver driver;
public hello1Page(WebDriver driver){
this.driver = driver;
}
public hello1Page method1 {... return this;}
public hello1Page method2 {... return this;}
}
This is test class :
public class hello1Test extends BaseTest
{
#Test(priority = 0)
public void methodT1(){
hello1page.method1();
}
}
I have other tests that follow this same pattern.
What I am assuming is when I run testng.xml, It should go to baseTest 2 times and open 2 chrome then run my 2 tests in separate chrome. But somehow this is not happening. It opens only 1 chrome browser and run only 1 test.
Normally everything works fine like run single test case using maven command but issue is with parallel.

I am expecting this is root cause
hellopage1 = PageFactory.initElements(driver, helloPage1.class);
In BaseTest.
In Pages, declare
WebDriver driver;
also
public className(WebDriver driver){
this.driver = driver;
}
In Test Case
WebDriver driver;
PageClassName obj;
#Test(priority=0)
public void test(){
//Create Login Page object
objLogin = new PageClassName(driver);

List item
Try with following steps :-
Create Threadsafe Webdriver instance like this :
private static ThreadLocal webDriver = new ThreadLocal();
Use getter and setter to use driver like this :-
public static WebDriver getDriver() {
return webDriver.get();
}
static void setWebDriver(WebDriver driver) {
webDriver.set(driver);
}
Add thread-count=2 (TestNg xml file) like this :-
Hope this will help .Thank You! Refer this for more info - https://rationaleemotions.wordpress.com/2013/07/31/parallel-webdriver-executions-using-testng/

Test framework architecture using Selenium WebDriver and TestNG

guys. I trying to solve a problem with parallel running using RC Webdriver and TestNG, but unfortunately, I can't find solution last few hours. Maby you will see the code, and show me what, I actually doing wrong.
Goal:
Create architecture using RC WebDriver and TestNG, with an ability to run tests on a remote machine.
Main settings class is Sut:
private RemoteWebDriver driver = null;
#BeforeClass
public WebDriver getWebDriver() {
DesiredCapabilities dc = new DesiredCapabilities();
FirefoxProfile fp = new FirefoxProfile();
dc.setCapability(FirefoxDriver.PROFILE, fp);
dc.setBrowserName(DesiredCapabilities.firefox().getBrowserName());
try {
driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), dc);
} catch (MalformedURLException e) {
e.printStackTrace();
}
return driver;
}
#AfterClass
public void tearDown() {
driver.quit();
}
In this class we have two methods: getWebDriver() - for setup our remote webdriver, and tearDown() - for close web-page, when a test will be complete.
Class BaseStep:
private static ThreadLocal<Sut> sut = new ThreadLocal<Sut>();
public static Sut getSut() {
Sut currentSut = sut.get();
if (currentSut == null) {
currentSut = new Sut();
}
return currentSut;
}
It's an additional layer, which create 'new state for each new thread'.
Few page objects:
public class FacebookPage {
public void testLink() {
getSut().getWebDriver().get("http://facebook.com");
}
}
public class GooglePage {
public void testLink() {
getSut().getWebDriver().get("http://google.com");
}
}
And scenarious classes:
public class VerifyGooglePage {
GooglePage googlePage = new GooglePage();
#Test
public void verifyGoogleMainPage() {
googlePage.testLink();
}
}
public class VerifyFacebookPage {
Facebook facebookPage = new Facebook();
#Test
public void verifyFacebookeMainPage() {
facebookPage.testLink();
}
}
And my and testNG.xml file for running
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite thread-count="1" name="Suite" parallel="tests">
<test name="FirstTest">
<classes>
<class name="scenarious.VerifyGooglePage"/>
</classes>
</test> <!-- Test -->
<test name="SecondTest">
<classes>
<class name="scenarious.VerifyFacebookPage"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
The problems is: When test complete, browser is not closed.
the Picture
I watched a lot of tutorials and articles in internet about it, but in no-one I cant found solution for my case. Could you please help me to find what I doing wrong.

Parellel testing with TestNG - Tests only run on one browser

I have created a test suite using
DataProvider
DataFactory
and my TestNG file is sending browser details as parameters. In testNG XML I'm calling my data factory class. I'm also using browsestack for testing (although I doubt this has anything to do with the problem I"m having)
Tests run without any issues when I don't add parrellel="true" to testng file.
I have a feeling it has something to do with same driver being used by each browser, but I'm out of depth to solve this at the moment.
Any guidance is appreciated.
Here's the code.
TestNG.XML
<suite name="Suite" verbose="1" parallel="tests">
<!-- Test with Chrome -->
<test name="ChromeTest" group-by-instances="true">
<parameter name="browser" value="Chrome"></parameter>
<parameter name="browserVersion" value="47"></parameter>
<parameter name="platform" value="Windows"></parameter>
<parameter name="platformVersion" value="7"></parameter>
<classes>
<class name="Resources.TestFactory"/>
</classes>
</test>
<!-- Test with Firefox -->
<test name="FirefoxTest" group-by-instances="true">
<parameter name="browser" value="Firefox"></parameter>
<parameter name="browserVersion" value="43"></parameter>
<parameter name="platform" value="Windows"></parameter>
<parameter name="platformVersion" value="7"></parameter>
<classes>
<class name="Resources.TestFactory"/>
</classes>
</test>
</suite>
Data Factory Class
public class TestFactory {
#Factory(dataProvider = "LoginCredentials", dataProviderClass=TestData.class)
public Object[] createInstances(int testNo, String userName, String password) {
Object[] result = new Object[1];
int i=0;
System.out.println("Inside LoginCredentials Factory - " + userName + "---" + password);
if(testNo==1){
result[i] = new Test_BookingEngine_Login(userName, password);
i++;
System.out.println("Object Array : " + Arrays.deepToString(result));
}
else if(testNo==2){
result[i] = new Test_BookingManagement_OpenBooking(userName);
i++;
System.out.println("Object Array : " + Arrays.deepToString(result));
}
System.out.println("outside for");
return result;
}
}
Suite - Driver Initialization
#BeforeTest
#Parameters(value ={"browser", "browserVersion", "platform", "platformVersion"})
public void initBrowser(String browser, String browserVersion, String platform, String platformVersion) throws Exception{
//Initializing browser in cloud
cloudCaps = new DesiredCapabilities();
cloudCaps.setCapability("browser", browser);
cloudCaps.setCapability("browser_version", browserVersion);
cloudCaps.setCapability("os", platform);
cloudCaps.setCapability("os_version", platformVersion);
cloudCaps.setCapability("browserstack.debug", "true");
cloudCaps.setCapability("browserstack.local", "true");
driver = new RemoteWebDriver(new URL(URL), cloudCaps);
}
Sample Test
public Test_BookingEngine_Login(String userName, String password) {
this.userName = userName;
this.password = password;
}
#Test (groups = {"Login"})
public void testHomePageAppearCorrect() throws InterruptedException{
//Starting test and assigning test category
test = logger.startTest("Login to Temptation", "<b>Successful user login or Pop up advising incorrect login details</b><br/><br/>" + browserInfo)
.assignCategory("Regression", "Booking Engine")
.assignAuthor("Dinesh Cooray");
System.out.println("Inside login test");
System.out.println("Browser inside login test : ");
driver.get("http://dev-thor2.tempoholidays.com/");
test.log(LogStatus.INFO, "HTML", "Navigated to http://dev-thor2.tempoholidays.com/");
//create Login Page object
objLogin = new BookingEngine_Login(driver);
//login to application
objLogin.loginToTemptationBookingEngine(userName, password, test);
//check if alert advising username or password is is incorrect
try {
//incorrect login details, user should not allow login
if(driver.switchTo().alert().getText().toLowerCase().contains("user name or password is wrong")){
test.log(LogStatus.INFO, "HTML", "<b>Popup - </b>" + driver.switchTo().alert().getText());
driver.switchTo().alert().accept();
Assert.assertTrue(true);
}
}

I am guessing RemoteWebDriver driver; would be a line you added at the class level.
What is happening is that you have already declared the variable at class level. i.e. memory is already allocated to it.When you do something like this driver = new RemoteWebDriver(new URL(URL), cloudCaps); you are just setting and resetting the values of the same variable in every #BeforeTest
What you need to do is create a factory that will return an instance of RemoteWebDriver based on a parameter you pass to it.Essentially the factory will create a new object and return only if an existing object doesn't exist.
Declare and initialise the driver (from factory) in your #Test Methods
Sample code for the factory would be something like
static RemoteWebDriver firefoxDriver;
static RemoteWebDriver someOtherDriver;
static synchronized RemoteWebDriver getDriver(String browser, String browserVersion, String platform, String platformVersion)
{
if (browser == 'firefox')
{
if (firefoxDriver == null)
{
DesiredCapabilities cloudCaps = new DesiredCapabilities();
cloudCaps.setCapability("browser", browser);
cloudCaps.setCapability("browser_version", browserVersion);
cloudCaps.setCapability("os", platform);
cloudCaps.setCapability("os_version", platformVersion);
cloudCaps.setCapability("browserstack.debug", "true");
cloudCaps.setCapability("browserstack.local", "true");
firefoxDriver = new RemoteWebDriver(new URL(URL),cloudCaps);
}
}
else
{
if (someOtherDriver == null)
{
DesiredCapabilities cloudCaps = new DesiredCapabilities();
cloudCaps.setCapability("browser", browser);
cloudCaps.setCapability("browser_version", browserVersion);
cloudCaps.setCapability("os", platform);
cloudCaps.setCapability("os_version", platformVersion);
cloudCaps.setCapability("browserstack.debug", "true");
cloudCaps.setCapability("browserstack.local", "true");
someOtherDriver = new RemoteWebDriver(new URL(URL),cloudCaps);
}
return someOtherDriver;
}
}
}

Webdriver object gets overwritten when tests are run in parallel

I'm writing Java based selenium-web-driver tests to run a parallel cross browser test using testng .
I have set the tests to run parallel on my xml file.The file looks like this :
<suite name="TestSuite" thread-count="2" parallel="tests" >
<test name="ChromeTest">
<parameter name="browser" value="Chrome" />
<classes>
<class name="test.login"/>
<class name="test.main"/>
<class name="test.logout"/>
</classes>
</test>
<test name="FirefoxTest">
<parameter name="browser" value="Firefox" />
<classes>
<class name="test.login"/>
<class name="test.main"/>
<class name="test.logout"/>
</classes>
</test>
But when i run test, both browser instances gets opened (Chrome opens first and starts execution and after a delay Firefox is opened).
In that case , the driver object gets overwritten by Firefox driver and chrome stops execution.Tests continue execution on Firefox and
gets completed successfully.
The structure of the project is like this :
Created a driverbase.class to load driver corresponding to browser which has my #Beforesuite.
Crteated individual classes for pages.(Eg: login.class , main.class etc) which has only #Test method and have extended driverbase class to get driver.
Test are run suceessfully when i set parallel to none on xml file
<suite name="TestSuite" thread-count="2" parallel="none" >
How can i overcome this issue? How to run tests in parallel without this issue?
The driverbase class is like this :
public class driverbase {
private String baseUrl;
private String nodeUrl;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();
public static WebDriver driver = null;
/**
* This function will execute before each Test tag in testng.xml
* #param browser
* #throws Exception
*/
#BeforeSuite
#Parameters("browser")
public WebDriver setup(String browser) throws Exception{
//Check if parameter passed from TestNG is 'firefox'
if(browser.equalsIgnoreCase("firefox")){
System.out.println("Browser : "+browser);
FirefoxProfile profile = new FirefoxProfile();
profile.setAcceptUntrustedCertificates(true);
//create firefox instance
driver = new FirefoxDriver(profile);
}
//Check if parameter passed as 'chrome'
else if(browser.equalsIgnoreCase("chrome")){
System.out.println("Browser : "+browser);
//set path to chromedriver.exe You may need to download it from http://code.google.com/p/selenium/wiki/ChromeDriver
System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--test-type");
//create chrome instance
driver = new ChromeDriver(options);
}
else{
//If no browser passed throw exception
System.out.println("Browser is incorrect");
throw new Exception("Browser is not correct");
}
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.manage().window().maximize();
return driver;
}
Thanks for the help :)

#BeforeSuite methods are not supposed to return something. => replace by void
Your testng has 2 differents tests, but #BeforeSuite will always be run once by suite what your comment shows you doesn't expect it. => replace by #BeforeTest
When you run in //, 2 threads are settings the driver value (one with firefox, one with chrome) which explains your problem.
You can try something like:
public class driverbase {
private String baseUrl;
private String nodeUrl;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();
public WebDriver driver;
#BeforeTest
#Parameters("browser")
public void setup(String browser) throws Exception {
if(browser.equalsIgnoreCase("firefox")) {
FirefoxProfile profile = new FirefoxProfile();
profile.setAcceptUntrustedCertificates(true);
driver = new FirefoxDriver(profile);
} else if(browser.equalsIgnoreCase("chrome")) {
System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--test-type");
driver = new ChromeDriver(options);
} else {
throw new Exception("Browser is not correct");
}
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.manage().window().maximize();
}
You should have a look on http://fluentlenium.org/ too.

To sure that same instance of webdriver won't be assigned to multiple tests. The method where driver instances are being created should be synchronized. This should solve the issue.
public synchronized void setup(String browser) throws Exception {
if(browser.equalsIgnoreCase("firefox")) {
FirefoxProfile profile = new FirefoxProfile();
profile.setAcceptUntrustedCertificates(true);
driver = new FirefoxDriver(profile);
} else if(browser.equalsIgnoreCase("chrome")) {
System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--test-type");
driver = new ChromeDriver(options);
} else {
throw new Exception("Browser is not correct");
}
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.manage().window().maximize();
}

NullPointer exception in TestNG while run test using xml

Try to automate my test using TESTNG framework in eclipse.
In Project I use one packet iEDGE and write all test methods in single Class named eLogin.
But when I try to execute the code it shows nullPointer exceptions.
Following is my sample code and xml settings that I use to run my test case.
Can any one help me to resolve my problem.
Package com.iEDGE;
public class eLogIn {
private WebDriver driver;
private String baseUrl;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();
#Parameters ( { "platform", "browser", "ver" } )
#BeforeMethod (alwaysRun=true )
public void setUp(#Optional String platform , #Optional String browser , #Optional String version ) throws Exception {
baseUrl = "Gmail URL";
DesiredCapabilities mCapability = new DesiredCapabilities();
if (platform.equalsIgnoreCase("WINDOWS")){
mCapability.setPlatform(org.openqa.selenium.Platform.WINDOWS);
}
if (browser.equalsIgnoreCase("Firefox")) {
mCapability = DesiredCapabilities.firefox();
mCapability.setVersion("40");
}
driver = new RemoteWebDriver(new URL(baseUrl), mCapability);
driver.manage().timeouts().implicitlyWait(1000, TimeUnit.MILLISECONDS);
driver.get(baseUrl);
driver.findElement(By.cssSelector("input[name=username]")).clear();
driver.findElement(By.cssSelector("input[name=username]")).sendKeys("username");
driver.findElement(By.cssSelector("input[name=password]")).clear();
driver.findElement(By.cssSelector("input[name=password]")).sendKeys("password");
driver.findElement(By.id("button-1015-btnInnerEl")).click();
}
//OTEHR TEST METHODS ....
}
TESTSuite.xml Settings
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite guice-stage="DEVELOPMENT" name="Default suite">
<test verbose="2" name="Default test">
<parameter name="platform" value="Windows"/>
<parameter name="browser" value="Firefox"/>
<parameter name="ver" value="40.0.3"/>
<classes>
<class name="com.iEDGE.eLogIn"/>
</classes>
</test> <!-- Default test -->
</suite> <!-- Default suite -->

Since all your parameter are annotated with #Optional, you will have to check if they are null before calling their methods. So, for example, you will have to do something like this:
if(platform != null){
if (platform.equalsIgnoreCase("WINDOWS")){
mCapability.setPlatform(org.openqa.selenium.Platform.WINDOWS);
}
}
Do this for all the instructions that involves these optional parameters.

You are passing wrong URL into " RemoteWebDriver(new URL(baseUrl), mCapability); "
You should pass selenium server url like below:
new RemoteWebDriver( new URL("http://localhost:4444/wd/hub"),
mCapability);
For more details follow:
seleniumHq
Let me know if you have any concern
Thanks
Sadik

you are intializing wrong Base url.
is supposed to be
baseUrl = "http://127.0.0.1:4888/wd/hub";
you have to mention which transfer protocol is used in your local host.
