Static Keyword:

1. The static keyword is applicable for the Class Members.
2. The static Class Members are accessed using Class Name.
3. Non static members are accessed using through reference variable or object.
4. The static members are loaded once into the memory for program execution.
5. The static members are shared across the objects.
6. Non-static & Static Class Members are inherited to the subclass

Static Program:

Static Example
Java

package org.totalqa.java; public class Student { int rollno=1; char section='A'; static String schoolName="ABC"; public static void main(String[] args) { Student s1 = new Student(); s1.rollno=2; s1.section='B'; System.out.println(s1.rollno); System.out.println(s1.section); Student s2= new Student(); System.out.println(s2.rollno); System.out.println(s2.section); System.out.println(Student.schoolName); //Can we call static class members using objects?? Yes System.out.println(s1.schoolName); s1.schoolName="DEF"; System.out.println(s2.schoolName); //can we call non-static using ClassName?? No //System.out.println(Student.rollno); } }

Student s1 = new Student();
s1.rollno=2;
s1.section='B';
System.out.println(s1.rollno);
System.out.println(s1.section);

Student s2= new Student();
System.out.println(s2.rollno);
System.out.println(s2.section);
System.out.println(Student.schoolName);

//Can we call static class members using objects?? Yes
System.out.println(s1.schoolName);

s1.schoolName="DEF";
System.out.println(s2.schoolName);

//can we call non-static using ClassName?? No
//System.out.println(Student.rollno);

In Collection Framework they are mainly 4 interfaces which mentioned as follows:

List,Set,Map,Queue

List:

List Interface

List is a type of Collection useful to store duplicate objects. In List elements are stored in index based. List allows null value. ArrayList,Vector and LinkedList are the classes implementing the List interface.

Iterator Interface:

Iterator Interface
Java

Collection API provides an iterator to Iterate each element of any collection type. Iterator has 3 methods: next():This method iterates to next Element and returns the element. If there is no next Element then NoSuchElementException thrown. hasNext():This method checks whether next element exists or not. If next element is present it returns true otherwise it returns false. remove():This method removes the Element from the Collection. When an Element is removed,the previous element point to the next Element.

Headless Browser-Selenium,HTMLUnitDriver

Headless Browser-Selenium,HTMLUnitDriver

Refer to the below Links for Practise

HtmlUnit

is a “GUI-Less browser for Java programs”. It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating Chrome, Firefox or Internet Explorer depending on the configuration used.
It is typically used for testing purposes or to retrieve information from web sites. HtmlUnit is not a generic unit testing framework. It is specifically a way to simulate a browser for testing purposes and is intended to be used within another testing framework such as JUnit or TestNG.

Refer to the document “Getting Started with HtmlUnit” for an introduction.

Selenium WebDriver Example:

1. Add the “htmlunit-driver-xxx-jar” from maven repository using the Download Link.
http://central.maven.org/maven2/net/sourceforge/htmlunit/htmlunit/2.13/htmlunit-2.13.jar
2. Add the downloaded jar to the build path of the project.
3. Execute the below program:

import org.openqa.selenium.By;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import com.gargoylesoftware.htmlunit.BrowserVersion;
public class HeadlessBrowser {
	public static void main(String[] args) {
		
		HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME);
		driver.get("https://www.indeed.co.in");
		String title = driver.getTitle();
		System.out.println("Title:"+ title);
	 	//Identify the element using id "what" and clear it
		driver.findElement(By.id("what")).clear();
		driver.findElement(By.id("what")).sendKeys("Selenium");
		//Identify the Element using id "where" and clear it
		driver.findElement(By.id("where")).clear();
		driver.findElement(By.id("where")).sendKeys("Bangalore");
		driver.findElement(By.id("fj")).submit();
	     title = driver.getTitle();
		System.out.println("Title:"+ title);
	}

}

import org.openqa.selenium.By;

import org.openqa.selenium.htmlunit.HtmlUnitDriver;

import com.gargoylesoftware.htmlunit.BrowserVersion;

public class HeadlessBrowser {

public static void main(String[] args) {

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME);

driver.get("https://www.indeed.co.in");

String title = driver.getTitle();

System.out.println("Title:"+ title);

//Identify the element using id "what" and clear it

driver.findElement(By.id("what")).clear();

driver.findElement(By.id("what")).sendKeys("Selenium");

//Identify the Element using id "where" and clear it

driver.findElement(By.id("where")).clear();

driver.findElement(By.id("where")).sendKeys("Bangalore");

driver.findElement(By.id("fj")).submit();

title = driver.getTitle();

System.out.println("Title:"+ title);

}

String value = driver.findElement(By.xpath("//span[text()='Create an account'")).getText();
System.out.println(value);
}
}

Console Output:

Exception in thread "main" org.openqa.selenium.InvalidSelectorException: Given xpath expression "//span[text()='Create an account'" is invalid: SyntaxError: The expression is not a legal expression. at org.openqa.selenium.remote.RemoteWebDriver.findElement(RemoteWebDriver.java:311) at Facebook.main(Facebook.java:12)

This exception is occurred due to the syntax error in Xpath.
Update the Xpath mentioned below:
//span[text()=’Create an acount’”]

Run-Time Exception: org.openqa.selenium.StaleElementReferenceException Indicates that a reference to an element is now “stale” — the element no longer appears on the DOM of the page.

public class Facebook { public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "geckodriver.exe"); WebDriver driver = newFirefoxDriver(); driver.get("http://www.facebook.com"); List<WebElement>inputList=driver.findElements(By.xpath("//input[@type='text']")); System.out.println("Number of input Elements:" + inputList.size()); driver.navigate().refresh();//Refresh the Page inputList.get(0).sendKeys("Fname"); } }

}

Console Output:

Number of input Elements:5 Exception in thread "main" org.openqa.selenium.StaleElementReferenceException: The element reference of <input id="u_0_j" class="inputtext _58mg _5dba _2ph-" name="firstname" type="text"> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

is stale; either the element is no longer attached to the DOM,
it is not in the current frame context, or the document has been refreshed

Solution:

In Selenium when the page is getting refreshed, the existing elements in the DOM removed and new elements are added. All the refernces to the previous elements are lost. We should try to find again once the refresh is done. driver.navigate().refresh(); inputList = driver.findElements(By.xpath("//input[@type='text']")); inputList.get(0).sendKeys("Fname");

Cucumber BDD with Selenium WebDriver and Testng Framework

Cucumber is a Behavior Driven Development (BDD) testing framework that helps the non technical members of the team can easily understand the scenario’s automating by testers. In Cucumber, the feature files plays very important role that contains plain English text written using gherkin language which is easy to understand. Refer to the Cucumber Basics

Cucumber-BDD using Page Object Model and Testng Framework:

1. Create a Maven Project with name as ‘cucumbermvn’. Refer to the steps->

https://total-qa.com/advanced-selenium/maven/

2. Add the following dependencies and plugins required for Cucumber,Selenium,Testng.
Refer to the dependencies for Cucumber – Java project

import org.testng.annotations.Test;

import cucumber.api.CucumberOptions;
import cucumber.api.testng.CucumberFeatureWrapper;
import cucumber.api.testng.TestNGCucumberRunner;

@CucumberOptions(
		features="src/test/resources/features",
		glue={"org.cucumber.stepdefs"},
		format=
				{"pretty",
				"html:target/cucumber-reports/cucumber-pretty",
				"json:target/cucumber-reports/CucumberTestReport.json",
				"rerun:target/cucumber-reports/re-run.txt"}
		)
public class OpenMRSTests  
{
	public static WebDriver driver;
	private TestNGCucumberRunner testRunner;
	
	@BeforeClass
	public void setUP()
	{
		System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
		driver = new ChromeDriver();
		testRunner = new TestNGCucumberRunner(OpenMRSTests.class);
		
	}
	@Test(description="login",dataProvider="features")
	public void login(CucumberFeatureWrapper cFeature)
	{
		testRunner.runCucumber(cFeature.getCucumberFeature());
	}
	@DataProvider(name="features")
	public Object[][] getFeatures()
	{
		return testRunner.provideFeatures();
	}
	@AfterClass
	public void tearDown()

format=

{"pretty",

"html:target/cucumber-reports/cucumber-pretty",

"json:target/cucumber-reports/CucumberTestReport.json",

"rerun:target/cucumber-reports/re-run.txt"}

)

public class OpenMRSTests

{

public static WebDriver driver;

private TestNGCucumberRunner testRunner;

@BeforeClass

public void setUP()

{

System.setProperty("webdriver.chrome.driver", "chromedriver.exe");

driver = new ChromeDriver();

testRunner = new TestNGCucumberRunner(OpenMRSTests.class);

}

@Test(description="login",dataProvider="features")

public void login(CucumberFeatureWrapper cFeature)

{

testRunner.runCucumber(cFeature.getCucumberFeature());

}

@DataProvider(name="features")

public Object[][] getFeatures()

{

return testRunner.provideFeatures();

}

@AfterClass

public void tearDown()

{

testRunner.finish();

}

5. Refer to the Step Definitions file LoginPage.java as mentioned below:

package org.cucumber.stepdefs;

 
import org.cucumber.tests.OpenMRSTests;
import org.openqa.selenium.By;
import org.testng.Assert;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;
 

public class LoginPage  
{
	@Given("^Open Application and Enter url$")
	public void open_Application_and_Enter_url() throws Throwable {
	  OpenMRSTests.driver.get("https://demo.openmrs.org/openmrs/login.htm");
	  
	}

	@When("^enter username$")
	public void enter_username() throws Throwable {
		OpenMRSTests.driver.findElement(By.id("username")).sendKeys("Admin");
	}

	@When("^enter password$")
	public void enter_password() throws Throwable {
		OpenMRSTests.driver.findElement(By.id("password")).sendKeys("Admin123");
		OpenMRSTests.driver.findElement(By.id("Inpatient Ward")).click();
		OpenMRSTests.driver.findElement(By.id("loginButton")).click();
	}

	@Then("^verify Msg$")
	public void verify_Msg() throws Throwable {
	   boolean result =  OpenMRSTests.driver.findElement(By.tagName("h4")).getText().contains("Logged");
	   Assert.assertTrue(result);
	}
}

package org.cucumber.stepdefs;

import org.cucumber.tests.OpenMRSTests;

import org.openqa.selenium.By;

import org.testng.Assert;

import cucumber.api.java.en.Given;

import cucumber.api.java.en.Then;

import cucumber.api.java.en.When;

public class LoginPage

{

@Given("^Open Application and Enter url$")

public void open_Application_and_Enter_url() throws Throwable {

OpenMRSTests.driver.get("https://demo.openmrs.org/openmrs/login.htm");

}

@When("^enter username$")

public void enter_username() throws Throwable {

OpenMRSTests.driver.findElement(By.id("username")).sendKeys("Admin");

}

@When("^enter password$")

public void enter_password() throws Throwable {

OpenMRSTests.driver.findElement(By.id("password")).sendKeys("Admin123");

OpenMRSTests.driver.findElement(By.id("Inpatient Ward")).click();

OpenMRSTests.driver.findElement(By.id("loginButton")).click();

Refer to the below Links for Practise

Access the URL to learn Maven Basics: https://total-qa.com/advanced-selenium/maven/
Maven is a Build Automation Tool helps in packaging different build types as Jar,War,EAR.
EAR -> Enterprise Archive
JAR -> JAVA Archive
WAR-> Web Archive
Refer to the link for more details: https://stackoverflow.com/questions/1594667/war-vs-ear-file

Sometimes, its require to run the Selenium WebDriver Automation tests against the Multiple Environments as DEV and QA. Maven has a provision of profiles which helps to run the test with multiple environments.

Configure the pom.xml with different profiles as mentioned below:

As we all familiar with different types of reporting Tools like XSLT Reporting,Allure Reporting mentioned below:
XSLT Report: https://total-qa.com/generate-xslt-report-ant-build/
Allure Report: https://total-qa.com/advanced-selenium/allure-reporting/

We will explore a new open source reporting tool Extent Reports in selenium webdriver.
Extent Reports is a logger-style API written for Java and .NET environments which allows creating HTML reports from tests.

Steps to Configure Extent Reports:

Access the link extent reports for maven dependency information

selenium webdriver headless chrome

total-qa    March 13, 2018 July 21, 2018    1 Comment on selenium webdriver headless chrome

Why Headless Chrome?

A headless browser is a great tool for automated testing and server environments where you don’t need a visible UI shell. This can be achieved by using Selenium Java Class org.openqa.selenium.chrome.ChromeOptions.

Refer to the Google Chrome Capabilities Link

Pre-requisites:

Chrome version installed should be greater then 59 version.

Use the latest version of chromedriver.exe downloaded from the link https://chromedriver.storage.googleapis.com/index.html?path=2.36/

Exception 1: unknown error: Chrome failed to start: was killed
Resolution:
Remove the following options from the code while running in windows.
options.addArguments(“–print-to-pdf”);
options.addArguments(“–screenshot”);

Exception 2: “unknown error: call function result missing ‘value'”
Resolution:
Download the latest version of chromedriver.exe solves this Issue.

Why Agile Methodology different from Other Methodologies??
Agile projects build software incrementally using short iterations of 1-4 weeks, to keep development aligned with changing business needs as compare to traditional Software Development Life Cycle mentioned below:

I1,I2,I3 are iterations mentioned below. This Iteration based “approach called as scrum. An Iteration also called as Sprint. The duration of the Iteration is 2-weeks.

Different Roles in Agile Methodology:

Scrum Master:

Facilitate Team Meetings and decision-making sessions.

Remove blocks and work with Organization to track progress.

Product Owner:

Defines the requirements.

Determine the release date.

Define the acceptance criteria.

Accept the Stories and the team definition of done.

What is a User Story?
A user story is a requirement that defines what functionality a user needs.

What is a task?
A task is how the functionality is implemented. Stories are implemented by tasks.

Agile FAQ’s
What is the right team size?

The team size is between five to nine people.

For 5 developers one tester is dedicated

for 9 developers two testers are dedicated.

They are lot of project management tools like Rally, Jira and Zephyr . For understanding the concepts in a better way we follow the steps on Jira Software.

Introduction:
Jira Software is an agile project management tool that supports any agile methodology . From agile boards to reports, you can plan, track, and manage all your agile software development projects from a single tool. Pick a framework to see how Jira Software can help your team release higher quality software, faster.

Try the downloading the Jira Software using the link -> https://www.atlassian.com/software/jira/try

Generate XSLT Report+ Ant build.xml+TestNG Fatal Error! Could not find function: if Issue +No suites, classes, methods or jar file was specified.

total-qa    March 9, 2018 July 21, 2018    1 Comment on Generate XSLT Report+ Ant build.xml+TestNG Fatal Error! Could not find function: if Issue +No suites, classes, methods or jar file was specified.

We usually depend on Testng for generating the default reports. Apart from that we use XSLT reports as well to generate PIE Charts based on Failed,Passed,Skipped Testcases.
During this process we face lot of issues. Few of the most commonly observed issues are as follows:

[xslt] Unknown file:23:146: Fatal Error! Could not find function: if
[xslt] : Fatal Error! Fatal error during transformation Cause: Fatal error during transformation

In order to resolve this we have to follow the below steps. At every step we will check and see whether issues are resolved or not.
Step 1 :
Make sure the build.xml file contains ‘SaxonLiaison’ processor added.
Example:

Java

<xslt in="${outputdir}/test-output/testng-results.xml" style="${basedir}/testng-results.xsl" out="${outputdir}/testng-xslt/index.html" processor="SaxonLiaison">

1

<xslt in="${outputdir}/test-output/testng-results.xml" style="${basedir}/testng-results.xsl" out="${outputdir}/testng-xslt/index.html"  processor="SaxonLiaison">

Re-run the build.xml and verify the issue is resolved. If still the issue is not resolved try performing Step2.
Step 2 :
Make sure the following jars added to the lib folder and Project build path as well.
saxon-8.7.jar -> Link to download the saxon jar-> Click here
SaxonLiaison.jar ->Link to download the SaxonLiaison jar-> Click here
guice-3.0.jar->Link to download guice-3.0.jar-> Click here

Re-run the build.xml and verify the issue is resolved. If the issue is not resolved goto Step3.
Step 3:

Refer to the build.xml mentioned below .Try to do necessary changes.
Re-run the build.xml and verify the issue is resolved.

Ant build.xml
