StepsToFollow

Create a maven project
Download basic dependecies, selenium-java and testng. Other dependencies will be added later
Create Base class, Global Env properties file, download browser drivers.
Create Base Test
If MacOS --> Navigatet to the folder where chromedriver is present and run the following command in terminal: xattr -d com.apple.quarantine chromedriver
Implement PageObject mechanism - create com.pageObjects and add pageObject classes to store objects of that page
Parameterizing test data with help of TestNG Dataprovider
Assertions
Create testng.xml file and create a testng suite containing all the tests.
Add @BeforeTest and @AfterTest methods
Integrate testng.xml into maven pom.xml. So that when use maven test...it triggers testng.xml...it inturn triggers all our test cases.
Adding logs using log4j
Modify testng.xml to create individual tests instead of all tests wrapped into a single test tag
Intialize a local webdriver instance to support parallel execution
Add parallel='tests' attribure in testng.xml to run tests parallely
Add screenshots on failures using TestNG Listeners
Add TestNG listener information to testng.xml file
Add extent reports to TestNG listener
Making f/w and extent reports thread safe uisng ThreadLocal<ExtentTest> class
