Compatibility Testing using BrowserStack & Selenium – TestNG

What is Compatibility Testing?

Compatibility testing is a non-functional test to ensure that an application’s compatibility within different environments such various web browsers with various versions, Operating Systems (Windows, Linux, Mac…). In order to pass this test, we also need to check Forward and Backward Compatibility. Here i’m using Browserstack to perform Compatiblity testing.

BrowserStack allows users to make manual and automation testing on different browsers and operation systems.To execute your test scripts using BrowserStack, you need to set parameters of Browsers and Platforms.
There are few steps to be followed to integrate Selenium with BrowserStack.

Step 1 : SignUp for BrowserStack account (Free Trail)
Step 2 : Get your UserName and Access Key (Click on Account at the top and click on ‘Automate‘)
Step 3 : Create your Test scripts using TestNG
Step 4 : Create a TestNG.xml file to run tests in parallel (set platforms and browsers with desired versions).
Step 5 : Execute TestNG.xml.
Step 6 : To view your results, Login and click on ‘Automate‘ link. You can view your project results.

Here I’m providing a sample code. I’m using TestNG to run tests in parallel.

package package1;

import java.io.File;
import java.io.IOException;
import java.net.URL;

import org.apache.commons.io.FileUtils;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.Assert;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class BrowserStackTestCase {

private WebDriver driver;
public static final String USERNAME = “YourUserName”;
public static final String AUTOMATE_KEY = “YourAccessKey”;
public static final String URL = “http://” + USERNAME + “:” + AUTOMATE_KEY
+ “@hub.browserstack.com/wd/hub”;

@BeforeTest
@Parameters(value = { “browser”, “version”, “platform” })
public void setUp(String browser, String version, String platform)
throws Exception {
DesiredCapabilities capability = new DesiredCapabilities();
capability.setCapability(“platform”, platform);
capability.setCapability(“browserName”, browser);
capability.setCapability(“browserVersion”, version);
capability.setCapability(“project”, “MyProject”);
capability.setCapability(“build”, “2.01”);
driver = new RemoteWebDriver(new URL(URL), capability);
}

@Test(priority = 1)
public void testcase001() throws Exception {
driver.get(“http://www.google.com”);
System.out.println(“Page title : ” + driver.getTitle());
Assert.assertEquals(“Google”, driver.getTitle());
WebElement element = driver.findElement(By.name(“q”));
element.sendKeys(“Merry christmas”);
element.sendKeys(Keys.ENTER);

}

@Test(priority = 2)
public void testcase002() {
driver.get(“http://seleniumhq.org”);
System.out.println(“Page title : ” + driver.getTitle());
Assert.assertEquals(“Selenium – Web Browser Automation”,
driver.getTitle());
}

@AfterMethod
public void takeScreenShot(ITestResult result) {
if (result.getStatus() == ITestResult.FAILURE) {
driver = new Augmenter().augment(driver);

File srcFile = ((TakesScreenshot) driver)
.getScreenshotAs(OutputType.FILE);
try {
FileUtils.copyFile(srcFile, new File(“D:\\Screenshot”
+ result.getParameters().toString() + “.png”));
} catch (IOException e) {
e.printStackTrace();
}
}
}

@AfterTest
public void tearDown() throws Exception {
driver.quit();
}

}

Now setup your configuration in xml file. Copy the below code.

<suite thread-count=”3″ name=”Suite” parallel=”tests”>
<test name=”FirstTest”>
<parameter name=”browser” value=”firefox” />
<parameter name=”version” value=”38″ />
<parameter name=”platform” value=”Windows” />
<classes>
<class name=”package1.BrowserStackTestCase” />
</classes>
</test>
<test name=”SecondTest”>
<parameter name=”browser” value=”safari” />
<parameter name=”version” value=”6.0″ />
<parameter name=”platform” value=”MAC” />
<classes>
<class name=”package1.BrowserStackTestCase” />
</classes>
</test>
<test name=”ThirdTest”>
<parameter name=”browser” value=”Internet Explorer” />
<parameter name=”version” value=”11″ />
<parameter name=”platform” value=”Windows” />
<classes>
<class name=”package1.BrowserStackTestCase” />
</classes>
</test>
</suite>

That’s it, your Testcases were executed. Just login and click on ‘Automate’ link, you will see your results.
I really thank BrowserStack team for making our job simpler.

Get Attribute Values Using Webdriver

There are cases where you want to get the attributes values and then perform any action.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class GetAttributes {

public WebDriver driver;
private By bySearchButton = By.name(“btnK”);

@BeforeClass
public void setUp() {
driver = new FirefoxDriver();
driver.get(“http://www.google.com/&#8221;);
}

@Test
public void getAttribute_ButtonName() {
WebElement googleSearchBtn = driver.findElement(bySearchButton);
System.out.println(“Name of the button is:- ” +googleSearchBtn.getAttribute(“name”));
}

@Test
public void getAttribute_Id() {
WebElement googleSearchBtn = driver.findElement(bySearchButton);
System.out.println(“Id of the button is:- “+ googleSearchBtn.getAttribute(“id”));
}

@Test
public void getAttribute_class() {

WebElement googleSearchBtn = driver.findElement(bySearchButton);
System.out.println(“Class of the button is:- “+ googleSearchBtn.getAttribute(“class”));

}

@Test
public void getAttribute_InvalidAttribute() {

WebElement googleSearchBtn = driver.findElement(bySearchButton);
//Will return null value as the ‘status’ attribute doesn’t exists
System.out.println(“Invalid Attribute status of the button is:- “+ googleSearchBtn.getAttribute(“status”));
}

@Test
public void getAttribute_ButtonLabel() {

WebElement googleSearchBtn = driver.findElement(bySearchButton);
System.out.println(“Label of the button is:- “+ googleSearchBtn.getAttribute(“aria-label”));
}

@AfterClass
public void tearDown() {
driver.quit();
}
}

How To Write Data in NotePad Using Selenium

Sometimes we have to print some data into Notepad according to our need.So this post helps you to write data into Notepad.

import java.io.BufferedWriter;
import java.io.FileWriter;
public class txt_write
{

public static void main(String[] args) throws Exception
{
FileWriter fr=new FileWriter(“e:\\data.txt”);
BufferedWriter br=new BufferedWriter(fr);

br.write(“This is sample”);
br.newLine();
br.write(“Testing tools”);
br.newLine();

br.close();

}

}

Test Case Grouping using TestNG ‘Groups’ Annotations

TestNG allows us to group several tests together. You can group certain tests based on what behavior/aspect they are actually testing. You may have a scenario where few tests belong to a certain group(say Regression) and other ones belong to other group(say Sanity) and yet another one belong to other group(say Login). With this approach you may decide to execute only certain group of test and skip other ones(let’s say there was a regression on related code, so we prefer to only execute Sanity related tests).The group test is a new innovative feature in TestNG, it doesn’t exist in Junit framework

Method annotated with @BeforeGroups gets executed only once for a group before any of the test of that group executes. Method annotated with @AfterGroups gets executed only once for a group only after all of the tests of that group finished execution.

Let’s see this with a simple example:

Review a test group example.

1. checkMail(),deleteMail() and composeMail() are belong to group ‘Sanity’.
2. checkDrafts(), checkAccountDetails() and checkPromotions() are belong to group ‘Regression’.
3. If i chose to execute only ‘Sanity’ then Step1 should be  executed.

package samples;

import org.testng.annotations.AfterGroups;
import org.testng.annotations.BeforeGroups;
import org.testng.annotations.Test;

public class TestNG_Groups {
@BeforeGroups(“Login”)
public void login_Account() {
System.out.println(“Account Login”);
}

@Test(groups = “Sanity”)
public void checkMail() {
System.out.println(“Checking Mail in the Inbox”);
}

@Test(groups = “Regression”)
public void checkDrafts() {
System.out.println(“Checking Drafts”);
}

@Test(groups = “Regression”)
public void checkPromotions() {
System.out.println(“Checking Promotions”);
}
@Test(groups = “Regression”)
public void checkAccountDetails() {
System.out.println(“Checking Account Details”);
}

@Test(groups = “Sanity”)
public void composeMail() {
System.out.println(“Send a Mail “);
}

@Test(groups = “Sanity”)
public void deleteMail() {
System.out.println(“Delete a Mail”);
}
@AfterGroups(“Login”)
public void logout_Account() {
System.out.println(“Account Logout”);
}
}

Now create testng.xml file,

<suite name=”Build 2.0.1″>

<test name=”groups Test”>
<classes>
<class name=”samples.TestNG_Groups” />
</classes>
<groups>
<run>
<include name=”Sanity” />
</run>
</groups>
</test>
</suite>

When you run this xml only the Sanity testcases should be executed.We can also use ‘exclude’ to exclude desired testcases.

How To Set Proxy Settings In Selenium WebDriver Test

How To Set Proxy Settings In Selenium WebDriver Test
Sometimes, You need to set proxy settings of browser to run your selenium webdriver test.
 As you know, selenium launch fresh browser every time you run test so default proxy setting
will be No Proxy. You can set It In two ways.
1. Creating firefox profile and then use that profile In selenium test.
2. Using DesiredCapabilities. We will use DesiredCapabilities of selenium to set proxy.
What is DesiredCapabilities?
Using DesiredCapabilities, we can set and configure webdriver browser driver Instance
settings before launching It. Simplest example Is -> I wants to set proxy settings for
my webdriver browser Instance. I can do It using DesiredCapabilities.

How to set proxy settings of browser using DesiredCapabilities
I have created simple example to set proxy settings for firefox browser. It will set firefox driver
 browser Instance proxy settings as bellow.

HTTP Proxy = localhost, Port = 8080
SSL Proxy = localhost, Port = 8080
FTP Proxy = localhost, Port = 8080
SOCKS Host = localhost, Port = 8080

Example to set proxy for firefox driver Instance.
package Testing_Pack;

import java.io.IOException;
import org.openqa.selenium.Proxy;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class ProxySettings {

 WebDriver driver;

 @BeforeTest
 public void setUpDriver() {
  //Set proxy IP and port. Here localhost Is proxy IP and 8080 Is Port number.
  //You can change both values as per your requirement.
  String PROXY = "localhost:8080";
  //Bellow given syntaxes will set browser proxy settings using DesiredCapabilities.
  Proxy proxy = new Proxy();
  proxy.setHttpProxy(PROXY).setFtpProxy(PROXY).setSslProxy(PROXY)
    .setSocksProxy(PROXY);
  DesiredCapabilities cap = new DesiredCapabilities();
  cap.setCapability(CapabilityType.PROXY, proxy);
  //Use Capabilities when launch browser driver Instance.
  driver = new FirefoxDriver(cap);
 }

 @Test
 public void start() throws IOException {
  System.out.println("Check your webdriver driver Instance's proxy setttings.");
 }
}

Run above example In your eclipse. It will open firefox browser driver Instance.
Check proxy settings for It from browser menu Tools -> Options -> Advanced tab -> Network tab -> Settings button. Click on Settings button. It will open connection settings popup as bellow.

You can see that proxy settings are set as given In test DesiredCapabilities configuration.

 You can change proxy IP and port number as per your requirement.

Maximize browser window using webdriver

Maximize browser window using webdriver

There are times when we want to to maximize the browser window during the execution of our script .For this purpose webdriver providers a built-in method and here is the syntax :

WebDriver driver;
driver.manage().window().maximize();

Here is the sample code using TestNG framework. :

import java.awt.Toolkit;
import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Reporter;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class MaximizeWindow {

WebDriver driver;

@BeforeTest
public void setUpDriver() {
driver = new FirefoxDriver();
      }
  

@Test
public void maximize() {
 //declare varibales for windows
org.openqa.selenium.Dimension defaultDim;
org.openqa.selenium.Dimension maximizeDim;
//Load google website on browser
driver.get("http://google.com");
//Display the current screen dimensions
defaultDim=driver.manage().window().getSize();
System.out.println("screenHeight before maximizing"+defaultDim.getHeight());
System.out.println("screenWidth before maximizing"+defaultDim.getWidth());
//maximize the window using webdriver method
driver.manage().window().maximize();
//Display the maximized window dimensions
maximizeDim=driver.manage().window().getSize();
System.out.println("screenHeight after maximizing:"+maximizeDim.getHeight());
System.out.println("screenWidth after maximizing:"+maximizeDim.getWidth());

      }


  }

Advanced Real time Grouping Test Methods | TestNG Process

Test Methods are annotated with @Test;  These methods can be grouped and executed separately using TestNG framework.
The methods can also be executed based on the priority.

Please find a Test Suite with real-time implementation as given below,

public class classname{
private WebDriver driver;
private String baseUrl;

  @BeforeTest(groups = { "Group1", "Group2" })
  public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "http://www.justdial.com";
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
  }

  @Test(groups = { "Group1" }, priority=3)
  public void test1() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G1a");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G1a");
  }

  @Test(groups = { "Group1" }, priority=2)
  public void test2() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G1b");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G1b");
  }

  @Test(groups = { "Group2" })
  public void test3() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G2a");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G2a");
  }

  @Test(groups = { "Group1" }, priority=1)
  public void test4() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G1c");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G1c");
  }

  @Test(groups = { "Group2" })
  public void test5() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G2b");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G2b");
  }

  @AfterTest(groups = { "Group1", "Group2" })
  public void tearDown() throws Exception {
    driver.quit();  
  }
