	*> If we are using the ChromeDriver driver it means we are invoking and act onlt the which implemented by the ChromeBrowser and Supported By ChromeBrowser;
	*> If We are using the WebDriveer driver it means we are creating an instance of WebDriver interface and casting it to ChromeDriver class.


	   driver object here has the access to the methods				driver object here has the access All the methods of ChromeDrover
	   Of ChromeDriver which are defined in the WebDriver Interface                  
	
		
	   Iska use kr k ham 1 code ko multiple browser m run kr skte h			 Iska use kr k ham 1 code ko only Chrome m run kr skte h kyu ki hm yha par

	  Yha par hm WebDriver Class k methods ko use kr skte hai                         Yha pa only ChromeDriver class k methods ko use kr skte hai. 
											 or code only chrome m chlega

	  WebDriver Class hai or ChromeDriver Interface					ChromeDriver Class hai or ChromeDriver Interface

	  *> Yha pr WebDrivere class ChromeDeriver() class m extendshoti h . or hm WebDrivere driver = new ChromeDeriver(); krte h , mtlb hm WebDriver ki properties access kr reh . Or ChromDriver driver =new ChromDriver() krenge to mtlb ChromeDeriver class ki properties access kr re h tabhi esa krne se test only chrome m chlte h .
	  *> WebDriver() parent class h or is classko sab classess access krti h , like Firefox chrome, edge etc.. tb Webdriver likhne se test sare browser m chlta h .
	  *> Is consept ko upcasting bhi khte h .

=> TYPES OF ANNOTATION HELPER FUNCTION IN TESTNG ?
ANSWER:
    1. timeout =500
    2. enabled = false
    3. depandsonMethod({"method", "method"});


1* depandsOnMethod	 :
	if we have method A and method B . and we are trying to excute method A  and method A is depends on method B in this case we will
	Use depandsOnMethod over method A. then the testNG excute method B first. we can pass multiple methods inside the depandsOnMethod
	liek:  depandsonMethod({"method", "method"});


2* enabled	 :
	if we want to skip ant particular methos while running testng.xml file in that case we will use enabled helper function.
	LIKE:  disable=true  or  disable=false;


2* timeOut	 :
	if we want to waite some time before execute any method in that case we will use @timeout=400 over that function.

QUESTION:
	 What is parameterization in TESTNG ?

ANSWER:
	if we want to set any global variables, then we can set that on our testng.xml file. 
	LIKE : <parameter name="URL" value="https://www.facebook.com/"/>
	ANd can access this URL variable on any function of suite. 
	before function use this keyword:   @Parameters({ "URL" })   and accessit as a argument. 

	*. <parameter/>  ko hm suite , test ya class  kisi base p bhi set kr skte hai.

QUESTION:
	WHAT IS PAGE OBJECT MODEL ?
	OR
	WHAT IS POM [Page Object Model] ?

ANSWER:
	 "Page object model" 1 'methology' hai , is  m hm sabhi locators k liye differenct class bna lete h or in class ko hm "Page object classes" kahte hai.
	 "Page object classes" ko hm reuse kr skte hai. or "page object methology" use krne se maintance problem resolve hoti h .
	 "Maintanance problem"  mtlb agr hm 1 hi class m sare locators lihk de to un m changes krne h kaafi issues aate hai. hme locators find krne m problem hoti h .

* => "Page object class" m hm 'driver.findElement(By.id("userID"));'   ko hm PageFactory ka use kr k likh skte h .
	-> @PageFactory 1 type ka annotation hota hai. 
	-> Syntax: @FindBy(id="userId"); // is ka mtlb [ driver.findElement(By.id("userID")) hi hota hai. ]
	->  @FindBy(id="userId"); iske liye hme  @PageFactory m driver pass krna hota h. kyu ki is syntax  m driver khi ni h .
	-> PageFactory.initElements(driver,driverValue) ->
	// ye syntax hm construct k ander krte hai. kyu ki driver ki value hm duri class se pass krte hai or contructor m likhne se class ka koi bhi @PageFactory call hone se phle use driver initilize hoga. 

Question:
	CAN WE APPLY @PageFactory WITH WebElement.findElement. like this ?

ANSWER:
	NO, it is not possible.

QUESTION:
	HOW CAN DISABLE WINDOWS ALERT/NOTIFICATIONS USING SELENIUM ?

ANSWER:
	By using addArgument(); method of chromeOptions class.
	SYNTAX: 

		ChromeOptions option=new ChromeOptions();
		option.addArguments("--disable-notifications");

Question:
	How can we change browserNameon run time.?

ANSWER:
	1*. Uske liye hmne 1 " .properties " extensions ki file bnani hoti h . like : "GlobalData.properties".
	2*. Fir us file ko "Basetest class"  m access kr lete hai [ prop.load(filesName); : ka use kr k ]. "Properties();" class ka object bna k 
	3*. Fir us file ko FileInputStream m convert krna hota hai.  kyu ki "prop.load()" function "FileInputStream" ko accept krta h .
	4*. prop.getProperty("browser"); ka use kr k browser ka name get kr lete h .
	5*. baseTest class ko hm  mainTest class  m extends kr lete h .

QUESTION:
	How can we un tests PAARALLELY?

ANSWER:
	Iske liye hmne "testng.xml" file m. <suite> tag  m [ parallel="test" ]  lihkna hoga. [ise likhne se jitne testCse honge utne browser 1sath open ho jayenge ]
	Agr hm chahte h ki 1 bar 2 ya3 browser hi open ho . to uske liye hm [ thread-count="3"  ]de skte h . <suite> tag m 
	
=> Agr hmne test cases ki grouping ki or kuchh methods m @BeforeMethod lga h to to vha p " alwaysRun=true" krna hotah.
   @beforeTest/@beforeMethods vale test ki grouping ni krte h is case m .

=> JB hme gunction bnate time data ka pta nahi hota h ki kis type ka data return hoga. tb hm data type "object" lete hai.
   -> Kyu ki "object" data type  sare type k data ko accpet krta hai.

=> 'DataProvidor' ka use kr k hm testcase ko multiple sest of data k sath test kr skte hai.
	EXAMPLE: 
	@DataProvider
	public Object[][] getTestData(){
		
		return new Object[][] {{"tom@example.com","Tom@1234","ZARA COAT 3"},{"sanjay@qa.com","Admin@123","ADIDAS ORIGINAL"}};
	}

	Access data ->  public void submitOrder(String email,String password,String productName) {
		/// logic
	 }

=> Jab hmate pass data jada hota h to hm Object se send nahi karte h kyuki object m jitne data hota h un sab ko
	-> access krne k liye function m utne hi argument pass krne hote h . line no. 1042 m example h. 
-> jada data send krne k liye hm HashMap ka use krte h .HashMap 1 array hota h JAVA M 
	Example:
		public Object[][] getTestData() {
		HashMap<String,String> map = new HashMap<String,String>();
		map.put("email","tom@example.com");
		map.put("password","Tom@123");
		
		HashMap<String,String> map1 = new HashMap<String,String>();
		map1.put("email","sanjay@qa.com");
		map1.put("password","Admin@123");
		
		return new Object[][] {{map},{map1}};
	}

-> For access : HashMap<String,String> input
		1. input.get("email); 2. input.get("password);, input.get("productName");

QUESTION:
	HOW CAN WE SEND DATA USING JSONN FILE ?

ANSWER:
	iske liye below steps follow krne ohhte hai .
	
	1. Phle hm 1 json file m sara testData likh lete hai.
	2. Phle hm JSON data ko string m convert krenge. "FileUtils.readFileToString()" ka use kr k.
	 Like: String jsonContent = 	FileUtils.readFileToString(new File(filePath),StandardCharsets.UTF_8);

	2. Fir String ko HashMap convert krenge "Jackson Databind" ka use kr k.
	   *. iske liye phle iski dependancy add krenge POM.XML file m  maven repo. se.
			[https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.13.4]
		-> iske liye phle "ObjectMapper()" class ka object bnayenge.
		   -:  ObjectMapper mapper = new ObjectMapper();
		List<HashMap<String, String>> data = mapper.readValue(jsonContent, new TypeReference<List<HashMap<String, String>>>() {
	    });
	3.  return data; [ ye data variable hme alag alag HashMap return krega like: //{map, map}  fir ise retun kr ]	

QUESTION:
	DIFFERENCE BETWEEEN "Assert" and "verify" comand ?

ANSWER:
	Assert : Jb bhi kois test case fail hoga to sctipt ka execution ruk jayega

QUESTION
	WHAT IS ExtendRport?

ANSWER:
	ExtendRport is graphical Representation of result of test casees.
	
		---[CONFIGURATION ]  OR STEPS FOR IMPLEMENT ----
	1. Sabse phle iski dependancy import hoti h pom.XML file m :
		LINK:-: https://mvnrepository.com/artifact/com.aventstack/extentreports/5.0.9
	2. 	ExtendRport bnane k liye hme [ExtentReports OR ExtentSparkReporter ] class ka use krna hota h.
	3. ExtentSparkReporter() is class se hm reprtName or page title set krte h .
	4. ExtentReports() is class se main report generate hoti h. IS m hm  "ExtentSparkReporter" class ka obj as a parameter pass krte h. jise ki hm reprtName or page title get ke skte hai.
	5. ExtentReports() se hm tester ka name bhi set kr skte hai.
	6. Jis test case ki extentReport bnani hoti h us k starting "ExtentReports" class k  " createTest("Test-Name"); " function use krte h ExtentReports class k ovj. ka use kr k.
	7. or last m ExtentReports() class k obj se flush(); function ko use krteh last test k bad. is se ye pta chl jata h ki ye last test case h
	
	--- IMPLEMENET --
	1. agr hm Ise testng k sath implement kr re h to sabse phle phle hme itest listener ko use krna hotah
	2. Fix IestListener ko apni testng.xml file m registre krna hota h .Like below.
		<listeners> <listener class-name="TestNG.Listener"></listener> </listeners>
	
	Example:  https://github.com/SanjuDeveloper/SeleniumFullCourse/blob/master/ExtentRport/src/test/java/core/ExtentRport/ExtentReportDemo.java



QUESTION:
	How can impement Extendt with testNG  ITestLISTENER?

ANSWER:
	1. Sabse ple hm 1 class bna lenge jiske ander 1 static function bnayenge jis m ectentReport bnane ka code hoga.
		Or is function m hm ExtentReports() Class ka object return krengge. kyu ki hm is object ko listeners m get krte h.
	EXAMPLE: https://github.com/SanjuDeveloper/SeleniumFullCourse/blob/master/MavenScrach/src/main/java/resources/ExtentReporterNG.java

	2. Fir hm 1 Class or bnayenge is m ITestLISTENER  interface ko implement kr lenge. 
	  ITestLISTENER interface m sare function hote h like :onTestStart() ,onTestSuccess()... ect..
	
	3. Fir hm onTestStart() function m ExtentReports k abject ko get kr k createTest() function ka use kr report bna lenge.

		EXAMPLE: https://github.com/SanjuDeveloper/SeleniumFullCourse/blob/master/MavenScrach/src/test/java/testComponents/Listeners.java#L18


--> WHAT ARE CONCURRENCY ISSUES  ?
	* Jb Hm Listeners ka use kr k extentReport bnate h or testCases ko parallely run krte h to . 
	-> TestCase ki report kbhi kabhi wrong aati h jo pass hota h vo fail show hota h or jo fail vo pass.
	-> KYU ki hm Hm extentreports ka 1 object get krte h listeners.java class m . m listeners m multiple testcase 
	->  sat h aate h . jb 1 test casee executehora h tb 2nd bhi aa jata h to extentReport confuse ho jati h
	-> ki knsa pass h or knsa fail kyuki object ki valuchange ho jati h . kyu ki object onTest Start m get krte h
	-> hm. jb tk 1st test case onFinish() vale function m pahuchta h tb tk object 2nd test case ko assign ho jata h
	-> to extenet report ko lgta h ki 2nd vala fail ho gya kyu ki usi time 2nd testcase OntestStart() function m
	->  hota h or use extentReport ka object assign ho jata h
	-> Is type k issue ko hi Cuncurrency issue khte h.

* Is problem ko fix krne k liye hm ThreadLocal() ka use krte h .
-> Iska use kr k hm hr 1 test case ko 1 usique ID dete h or fir listener sare function usi ID k throught execute hote h.
-> Ab  Listener m jo case phle aayega use uski ID milegi or vo fir 2nd vale ko uski ID or usi ID se baki listener k function execute hoge.
Example:
-> SeleniumFrameworkDesign\src\test\java\rahulshettyacademy\TestComponents\Listeners.java  [IS M H ]
ThreadLocal<ExtentTest> extentTest = new ThreadLocal<ExtentTest>(); //Thread safe	test = extent.createTest(result.getMethod().getMethodName());
extentTest.set(test);//unique thread id(ErrorValidationTest)->test


QUESTION:
	HOW TO RERUN THEFAILED TEST CASE:

ANSWER:
	By implement the "IRetryAnalyzer" interface.

	1. hm 1 calss retry.java name se bna lenge. or Is class m IRetryAnalyzer interface ko implement kr lenge. 
	2. isme retry() function hota h jo testcase ko rerun krta h . 
	3. jb tk ye funtion true return krega tk tk test case rerun hoga.
	4. ByDefault isme false return hota h .
	5. Hm if condition lga k jitni bar test case rerun krana h utni bar true return kra denge.
	6. Fir jis test case ko rerun krana h us m [ retryAnalyzer=Retry.class]  lga denge.

	EXAMPLE:
		LINK: https://github.com/SanjuDeveloper/SeleniumFullCourse/blob/master/MavenScrach/src/test/java/testComponents/Retry.java
		LINK: https://github.com/SanjuDeveloper/SeleniumFullCourse/blob/master/MavenScrach/src/test/java/seleium/MavenScrach/ErrorValidationsTest.java#L14


=> Why we use MAVEN ?
-> Maven se hm test cases ko command se run kr skte h .

QUESTION:
	HOW CAN WE RUN TESTCASE USING COMMAND:

	1. sabse phle hme apne system maven install krna hota h :
	
	  link: https://www.qamadness.com/knowledge-base/how-to-install-maven-and-configure-environment-variables/

		Private WebElement submit; // encapsulation

	1. Hmne PageFactory element ko private bna diya ab jo bhi is class ko inherite krega vo only methonds ko access kr payega.
	   submit WebElement element ko access ni kr payega. hmne submit WebElement ko hinde kr diya.
	   [ encapsulation ka example hota h ki methods 1 class m bna lo or fir us calss ko inherite kr object se onmy method call kr lo . method ka logic hide rhega.]		

QUESTION:
	Do your framework support  run parallel test ? How can you write Thread safe code ?

ANSWER:
	Yes, Our framework support parallely run test. 
	For Thread safe code . hm ThreadLocale class ka use krte h .

	HOW CAN YOU SOLVE CONCURRENCY ISSUE ? 

ANSWER:
	By uing ThreadLocale method. 
	CONCURRENCY issue tb aata h jb hm every test case ki a sigle report bnate h parallely run rk k to ItestListener class m WhentestStart method.
	Variable ki value override ho jati h . fir ThreadLocale class ka use kr k variable ko saparaly identifiy kra dete h.


Question:
	Do you have static keywords in your framework. ?

ANSWER:
	Yes we can mark static only  thoes varialbes which are common for all test case. like Properties object [Properties object se .properties file ko read krte h ] 
	1. HME driver object ko static nahi mark krna hota h kyu ki agr driver ko static mark kr denge to every test case k liye smae driver kaam krege or test cases m issue aayenge
	2. Agr driver object static mark kr denge to Cuncurrency issue aayega.

	---------  OOPS Interview questions  --------

1. What are the core concepts of OOPS?
	ANSWER:
		OOPS core concepts are;
		Abstraction
		Encapsulation
		Polymorphism
		Inheritance
		Composition
		Association
		Aggregation

2. What is Abstraction?
	ANSWER:
		Abstraction is an OOPS concept to construct the structure of the real world objects. During this construction only the general states and behaviors are taken and more specific states and behaviors are left aside for the implementers.

3.  What is Encapsulation?
	ANSWER:
		Encapsulation is an OOPS concept to create and define the permissions and restrictions of an object and its member variables and methods. A very simple example to explain the concept is to make the member variables of a class private and providing public getter and setter methods. Java provides four types of access level modifiers: public, protected, no modifier and private.

5. What is Polymorphism?
	ANSWER:
		Polymorphism is the occurrence of something in various forms. Java supports various forms of polymorphism like polymorphic reference variables, polymorphic method, polymorphic return types and polymorphic argument types.

6. What is Inheritance?
	ANSWER:
		A subclass can inherit the states and behaviors of it’s super class is known as inheritance.

7. What is multiple inheritance?
	ANSWER:
		A child class inheriting states and behaviors from multiple parent classes is known as multiple inheritance.

8. What is the diamond problem in inheritance?
	ANSWER:
		In case of multiple inheritance, suppose class A has two subclasses B and C, and a class D has two super classes B and C.If a method present in A is overridden by both B and C but not by D then from which class D will inherit that method B or C? This problem is known as diamond problem.

9. Why Java does not support multiple inheritance?
	ANSWER:
	Java was designed to be a simple language and multiple inheritance introduces complexities like diamond problem. Inheriting states or behaviors from two different type of classes is a case which in reality very rare and it can be achieved easily through an object association.

10. What is Static Binding and Dynamic Binding?
	
	ANSWER:
		Static or early binding is resolved at compile time. Method overloading is an example of static binding.
		Dynamic or late or virtual binding is resolved at run time. Method overriding is an example of dynamic binding.

11. What is a Class?
	ANSWER:
		A class is the specification or template of an object.

12 What is an Object?
	
	ANSWER:
		Object is instance of class.

	--------------  Java interview questions  -----------

1. What is Runtime Polymorphism?

	ANSWER:
		Runtime polymorphism or dynamic method dispatch is a process in which a call to an overridden method is resolved at runtime rather than at compile-time.
		In this process, an overridden method is called through the reference variable of a super class. The 

3. What is abstract class?
	
	ANSWER:
		A class that is declared as abstract is known as abstract class. It needs to be extended and its method implemented. It cannot be instantiated.

 4. Can there be any abstract method without abstract class?
		ANSWER:
		No, if there is any abstract method in a class, that class must be abstract.

5. Can you use abstract and final both with a method?
	
	ANSWER:
		No, because abstract method needs to be overridden whereas you can't override final method.

6. Is it possible to instantiate the abstract class?
	
	ANSWER:
		No, abstract class can never be instantiated.
7. What is interface?
	
	ANSWER:
		Interface is a blueprint of a class that have static constants and abstract methods.It can be used to achieve fully abstraction and multiple inheritance.

 8. Can you declare an interface method static?

	ANSWER:
		No, because methods of an interface is abstract by default, and static and abstract keywords can't be used together.

 9. Can an Interface be final?
	ANSWER:
		No, because its implementation is provided by another class.

 10 What is marker interface?

	ANSWER:
		An interface that have no data member and method is known as a marker interface.For example Serializable, Cloneable etc.

 11. What is difference between abstract class and interface?
	
	ANSWER:
		Abstract class	Interface
		1)An abstract class can have method body (non-abstract methods).	Interface have only abstract methods.
		2)An abstract class can have instance variables.	An interface cannot have instance variables.
		3)An abstract class can have constructor.	Interface cannot have constructor.
		4)An abstract class can have static methods.	Interface cannot have static methods.
		5)You can extends one abstract class.	You can implement multiple interfaces.
	
12.Can we define private and protected modifiers for variables in interfaces?
		ANSWER:
	No, they are implicitly public.

 13. When can an object reference be cast to an interface reference?

	ANSWER:
		An object reference can be cast to an interface reference when the object implements the referenced interface.
