How to improve performance of the script in selenium webdriver?

1.How to improve performance of the script in selenium webdriver?
2.isDiplayed() takes more time when element is not present how to over come this?

Ans-  1. use By.id(String arg) locator while locating any element. Avoid to use xpath in script because that always take time and reduce the performance but if xpath is required then use xpath.
2. isDisplayed() obviously will wait till the time webelement will not be visible so for this also use By.id to locate the element fast. One reason could be your internet speed.

There are 100 testcases i want to execute only 3 test cases without using testng groups?

Note- just include those methods in testng.xml which you want to execute.

For ex- inside com.CC.scripts.Login class there are 100 test cases but you want to execute only 3 methods- at_loginValid, at_loginBlank and at_loginInValid. In that case you can edit your xml as below-

<suite name="Suite" parallel="none">
<test name="Test">
<classes>
<class name="com.CC.scripts.Login">
<methods>
<include name="at_loginValid"></include>
<include name="at_loginInValid"></include>
<include name="at_loginBlank"></include>
</methods>
</class>
</classes>
</test>
</suite>


Login class- Here hello method will not execute by using above testng.xml

package com.CC.scripts;
import org.testng.annotations.Test;

public class Login {
    @Test
    public void at_loginValid(){
        System.out.println("at_loginValid");
    }
    @Test
    public void at_loginInValid(){
        System.out.println("at_loginInValid");
    }
    @Test
    public void at_loginBlank(){
        System.out.println("at_loginBlank");
    }
    @Test
    public void hello(){
        System.out.println("hello");
    }
}

What is the alternate way to send text in textbox of webpage with out using sendKeys() method ?

Note- Use Javascript to send text.

syntax-

((JavascriptExecutor)driver).executeScript("document.getElementById('attribute value of id').value='text which you want to pass'");

ex-
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class WithoutSendKeys {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("https://accounts.google.com/ServiceLogin?sacu=1&scc=1...");
((JavascriptExecutor)driver).executeScript("document.getElementById('Email').value='sanjay'");
}
}

How to execute a test case multiple times or use of 'invocationCount'

Note- invocationCount , this determined how many times the test case should execute.

ex- This will execute 5 times.

import org.testng.annotations.Test;

public class RunTestMultipleTimes {
    @Test(invocationCount=5)
    public void runMultipleTimes(){
        System.out.println("run this test");
    }
}

Output
---------

run this test
run this test
run this test
run this test
run this test
PASSED: runMultipleTimes
PASSED: runMultipleTimes
PASSED: runMultipleTimes
PASSED: runMultipleTimes
PASSED: runMultipleTimes

How to skip a test case in TestNG or use of parameter 'enabled'

Note- By default every @Test has enabled=true.

ex-

import org.testng.annotations.Test;

public class Enabled {
    @Test                            
    public void defaultEnabled(){
        System.out.println("by default enabled=true");
    }
    @Test(enabled=true)
    public void trueEnabled(){
        System.out.println("hard coded enabled=true");
    }
    @Test(enabled=false)
    public void falseEnabled(){
        System.out.println("this test case will be skipped because enabled=false");
    }
}

How to change the position of the open browser window.

Note - use command -> driver.manage().window().setPosition(new Point(int value1,int value2));

import java.awt.AWTException;
import org.openqa.selenium.Point;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class MoveWindow
{
public static void main(String[] args) throws InterruptedException, AWTException
{
    WebDriver driver = new FirefoxDriver();
    driver.manage().window().setPosition(new Point(0,0)); //move the window to top right corner
    Thread.sleep(2000);
    driver.manage().window().setPosition(new Point(500,400)); //move the window to 500unit horizontally and 400unit vertical
}
}

How to execute the testcases parallely in TestNG

Test cases can be run parallel by updating testng.xml.

ex- Here two browsers will open as thread-count = "2" (you can change it according to your requirement). In one browser all the classes will be executed which are under 1st test and in 2nd browser, all the classes will be executed which are under 2nd test.

<suite name="Suite" parallel="tests" thread-count="2">
  <test name="Test1">
    <classes>
      <class name="Library.Module1"/>
    </classes>
  </test>
  <test name="Test2">
    <classes>
      <class name="Library.Module2"/>
    </classes>
  </test>
</suite>

Integrate Automation framework with Build using Jenkins.

‘Jenkins’ is a tool which is used for continuous integration testing.

Please follow the below steps to configure the Jenkins with your Automation Framework-

Step1- click on this link : http://jenkins-ci.org/
Step2- click on ‘Long term support release’ tab which is there in right side.
Step3- click on 'older but stable' then one pop-up will come to save the file & there in pop-up click ‘OK’ which will save Jenkins the war file in the Downloads folder, copy paste the downloaded file inside the project.
Step4- Open the command prompt (cmd) and go to project directory.
For ex- say your project directory is -> C:\selenium\SpiceJet\Owler
so here you open cmd, then give command as cd C:\selenium\SpiceJet\Owler and hit enter
Step5- Then type the command ‘java –jar jenkins.war’ & hit enter.
Step6- If Jenkins server is loaded successfully it will display following message in command prompt.      Jenkins is fully up and running

Step7- Now open the browser & enter the following URL in the address bar “local host:8080” which will display homepage of the Jenkins server.
Step8- Click on New Job & specify the job name
For ex: AutomationFramework
Step9- Select the first radio button ‘Build a free-style software project’ then click on OK.
Step10- Click on ‘Advanced’ & select last checkbox 'use custom workspace' under ‘Advanced Project options’ section.
Step11- Type the java project path in the directory (For ex- the java project path –
C:\selenium\SpiceJet\Owler)
Step12- Go down, There you will find Build section, there click on ‘Add Build Step’ & select ‘Execute Windows Batch Command’ & type ‘RunMe.bat’ in the command field.
**How to create RunMe.bat file -
             a) open notepad
             b) paste this command- java -cp bin;jars/* org.testng.TestNG testng.xml
             c) save the file as RunMe.bat
Step13- Go down and click on Save button.
Step14- Now you are all set to use Jenkins. Click on Build Now. It will start the execution of your framework.
Note- In order to create a Build, Developer clicks on ‘Build Now’ which will start the Build creation process once the build is created it will start Framework execution automatically. Every time when we run the build, Jenkins will display a link under Build History, the name of the link will be current system Date & Time, when we click that link it will take us to Build details page where if we click on ‘Console output’ link it will display output of the Automation Framework which is printed on the command prompt.

Please find snapshot below, where you should put .bat file and jenkins.war
