Section: Framework Building from Scratch - Real Time Project

Building Framework From Scratch

1. Creating of Maven Project

2. Creating Base and Utility Functions

3. Organize Page Objects

4. Adding Tests

5. Data Driving and Parameterizing Tests

6. Converting into TestNG Framework

7. TestNG Listeners

8. Screenshot on Test Failures

9. Creating Excellent HTML reports for Test Results

10. Jenkins - Continuous Integration

Creation of Maven Project

1. Create a Maven Project

	>cd <eclipse-workspace>
	>mvn archetype:generate -DgroupId=Academy -DartifactId=E2EProject -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

2. Compatible with Eclipse

	>cd <root directory of the new project>
	>mvn eclipse:eclipse

3. Import the project to Eclipse

• Open Eclipse
• Files ==> Import...
• Select ==> Maven//Existing Maven Project ==> Next
• Maven Projects ==> Browse ==> Project Root Folder ==> Select Folder ==> Finish
• The project will be imported into Eclipse shortly.

• src/test/java - All the test cases created here
• src/main/java - All the utilities, base objects, data and etc.
• pom.xml - the maven configure file

4. Add All Dependencies and Plugins to pom.xml

• Selenium Dependency ==> search "Selenium Maven Information"

    <dependency>
    	<groupId>org.seleniumhq.selenium</groupId>
    	<artifactId>selenium-java</artifactId>
    	<version>3.141.59</version>
    </dependency>
  

• TestNG Dependency ==> search "TestNG Maven Dependency"

    <dependency>
    	<groupId>org.testng</groupId>
    	<artifactId>testng</artifactId>
    	<version>6.8</version>
    	<scope>test</scope>
    </dependency>
  

• Save "pom.xml" will get all the dependencies added to the project local repository.

Creating Base and Utility Functions

1. Create base java class in src/main/java

2. Create public void initializeDriver() method

3. java.lang.NullPointerException

if (browserName == "chrome") - wrong. shouldn't use "==".

extract the value from property file, need use browserName.equalsTo("String");

• == is a reference comparison, i.e. both objects point to the same memory location
• .equals() evaluates to the comparison of values in the objects

4. data.properties

• each line ended without semicolon otherwise will cause the problem.

Creation page objects

1. Create base java class in src/main/java

2. Create public void initializeDriver() method

3. java.lang.NullPointerException

if (browserName == "chrome") - wrong. shouldn't use "==".

extract the value from property file, need use browserName.equalsTo("String");

• == is a reference comparison, i.e. both objects point to the same memory location

• .equals() evaluates to the comparison of values in the objects

• need give the live of driver in LandingPage class

    public WebDriver driver;
    public LandingPage(WebDriver driver) {
    	this.driver = driver;
    }
  

4. data.properties

• each line ended without semicolon otherwise will cause the problem.

5. TestNG maven integration

• Right click the Project-Name ==> TestNG ==> Convert to TestNG

• "testng.xml" file will be created.

• Right click "testng.xml" ==> Run As ==> TestNG Suite

• Running as mvn project from command line

    >cd <project root directory>
    >mvn compile
    >mvn test
  

6. Integrate Log4j to Maven build

• Search log4j maven dependency

• Append the dependency to pom.xml

• Check if Project//Build Automatically is selected.

• Add resource folder of "log4j.xml" to "pom.xml" file

  src/main/recources true

• Add the source file to java build path - otherwise the system does not know where to find the log4j2.xml configuration file.2

• right click project ==> Build Path ==> Configure Build Path... ==> Java Build Path//Source Folde

7. Fix the framework issues by tweaking TestNG configuration file.

• The 1st and 2nd windows are not closed before the 3rd window opens. They all closed after the tests are completed.
• This is because the TestNG configured the 3 classes inside 1 test.
• Define each class under 1 set of the test to avoid the windows closing issue.
• put "driver = null;" after driver.close(); -- release the memory.
• Change the driver initialize to static that has more advantages.

8. Screenshot on Failure - TestNG Listeners

• Add Apache commons-io maven dependency to pom.xml

• Add getScreenshot() method in base class

• Create a listener class and implements ITestListener

• Invoke getScreenshot() in Failed Listener.

• Configure testng.xml - adding the listener.

    	<listeners>
    		<listener class-name="Academy.Listeners"/>
    	</listeners> 
  

9. Excellent HTML Reports on Test Execution - Extent - Report API & Dashboard

• Get the dependency of "extentreports" and add it to pom.xml
• Get the ExtentReporterNG.java class to be added to the project
• Add ExtentReporterNG as a listener.

10. Integrate the project to Jenkins CI tool

• Jenkins installation
• http://localhost:8080/ - Jenkins console
• Jenkins ==> Manage Jenkins ==> Global Tool Configuration

• JDK setup
• GIT setup
• Maven setup

• New Item ==> Enter"E2EProject" ==> General ==> Advanced ==> Use custom workspace
• Build ==> Add build step ==> Invoke top-level Maven targets ==> put the mvn command to the Goals
• Optional - Build Triggers ==> Build periodically

11. Parameterize Jenkins Build with different browsers execution

12. Coding Standards - Private locators & Public methods to achieving Encapsulation

• OOPS Principle Framework

13. Remove hard coded Paths from everywhere in the Project

14. Achieve Chrome Headless Execution Mechanism

15. How Inheritance is achieved in Framework

16. Where are Interfaces used in the framework

17. Can there be multiple @Test methods in one single class? What changes needed in Testng.xml file to club multiple @Test methods into one single Test Tag.

18. Can driver be static without initializing it form every Test?

19. Enhancement

• Add the timestamp to the screenshot file.

• Add the webdrivers to resources folder and change the path to dynamic path
