1) What is TestNG?
TestNG is a testing framework inspired from JUnit as well as NUnit exactly introducing about novel functionalities that arrive to a greater extent than powerful as well as easier to use.
2) What is TestNG inwards Selenium?
Using TestNG framework inwards Selenium nosotros can,
> Generate Detailed (HTML) Test Reports.
> Group Test cases.
> Parallel Test execution.
> Parameterize Tests
> Execute multiple classes / programs using XML file etc...
3) How to install TestNG inwards Eclipse?
In Eclipse IDE,
Help bill of fare -> Install New Software -> Click Add
> Enter refer every bit "TestNG"
> Enter url as: "http://beust.com/eclipse/"
> Select "TestNG"
> Next > Next > stimulate got the Agreement > finish
4) Give a TestNG Program example?
public cast TestNGexample {
@Test
public void verifyTitle() {
WebDriver driver = novel FirefoxDriver();
driver.get("http:\\gmail.com");
String Actual = driver.getTitle();
Assert.assertEquals(Actual, "Gmail");
}
}
Note:
> primary method is non required for TestNG programs.
> TestNG programme contains methods that incorporate @ annotations.
> If nosotros don't write @Test Annotation as well as thus the method won't endure executed.
5) What are the of import TestNG Annotations?
Important TestNG Annotations are:
@Test - Annotation for every Test (Method)
@BeforeMethod - pre-condition for every try illustration inwards a program.
@AfterMethod - Post status for every try illustration inwards a program.
@BeforeClass - pre status for all try cases inwards a program/class
@AfterClass - post status for all try cases inwards a program/class
@BeforeTest - pre status for all try cases inwards multiple classes/programs
@AfterTest - post status for all try cases inwards multiple classes / programs
6) How to practice multiple Test cases inwards a program/class?
public cast TestNGexample {
@Test
public void testA () {
Assert.assertEquals("Gmail", "Gmail");
}
@Test
public void testC() {
Assert.assertEquals("Gmail", "Gmail");
}
@Test
public void testB() {
Assert.assertEquals("abc", "abc");
}
}
As per TestNG program:
A
C
B
---------------------
Execution Flow:
A
B
C
-------------------------
If yous desire to command the Test execution catamenia as well as thus utilization "priority" Attribute.
Syntax:
@Test (priority = number")
Example:
public cast TestNGexample {
@Test (priority=1)
public void testA () {
Assert.assertEquals("Gmail", "Gmail");
}
@Test (priority=2)
public void testC() {
Assert.assertEquals("Gmail", "Gmail");
}
@Test(priority=3)
public void testB() {
Assert.assertEquals("abc", "abc");
}
}
7) How to execute multiple programme or classes?
Using XML file nosotros tin execute multiple Java programs or classes at a time.
8) How to practice XML file?
Create XML file
Select Java Project as well as Right click
> New
> Other
> Enter XML as well as Select XML file
> Enter File Name
> Finish
9) Give an illustration for executing multiple programs or classes?

<test refer ="Sanity Tests">
<classes>
<class name="javaExamples.Class1"/>
<class name="javaExamples.Class2"/>
</classes>
</test>
</suite>
---------------------
Class 1:
public cast Class1 {

populace void advancedSearch(){
System.out.println("Advanced Search Successful");
}
@Test(priority=3)
populace void buyProducts(){
System.out.println("Buying Products Successful");
}
}
-------------------------------
Class 2:

populace void logout(){
System.out.println("Logout Successful");
}
@Test
populace void accountSummary(){
System.out.println("Account Summary Successful");
}
@Test
populace void fundTransfer(){
System.out.println("Fund Transfer Successful");
}
@Test
populace void billPayment(){
System.out.println("Bill Payment Successful");
}
}
--------------------------------
10) Give an illustration for parallel Test execution?
XML File
<suite refer = "Parallel Test suite" parallel = "classes" thread-count = "2">
<test refer = "Sanity Test">
<classes>
<class refer = "seleniumTests.Class1"/>
<class refer = "seleniumTests.Class2"/>
</classes>
</test>
</suite>
------------------------
parallel = "methods": TestNG volition run all the methods inwards split upwards threads.
parallel = "classes" : TestNG volition run all the methods inwards the same cast inwards the same thread.
parallel = "tests" : TestNG volition run all the methods inwards the same <test> tag inwards the same thread.
------------------------
Class 1
public cast Class1 {
@BeforeTest
populace void login(){
System.out.println("Login Successful");
}
@AfterTest
populace void logout(){
System.out.println("Logout Successful");
}
@Test (priority = 1)
populace void search(){
System.out.println("Search Successful");
}
@Test (priority = 2)
populace void advancedSearch(){
System.out.println("Advanced Search Successful");
}
@Test (priority = 3)
populace void buyProducts(){
System.out.println("Buying Products Successful");
}
@Test (priority = 4)
populace void testCase(){
System.out.println("Test Case inwards "+getClass().getSimpleName()
+ " With Thread id: " + Thread.currentThread().getId());
}
}
-----------------------------------------
Class 2

<class refer = "seleniumTests.GroupTests"/>
<class refer = "seleniumTests.GroupTests2"/>
</classes>
</test>
</suite>
-------------------------------
Java Program/Class file
@BeforeTest (groups ={"sanity","regression"})
populace void login(){
System.out.println("Login Successful");
}
@AfterTest (groups ={"sanity","regression"})
populace void logout(){
System.out.println("Logout Successful");
}
@Test (groups ={"sanity"})
populace void search(){
System.out.println("Search Successful");
}
@Test (groups ={"sanity","regression"})
populace void advancedSearch(){
System.out.println("Advanced Search Successful");
}
@Test (groups ={"sanity", "regression"})
populace void buyProducts(){
System.out.println("Buying Products Successful");
}
@Test (groups ={"regression"})
populace void abcd(){
System.out.println("Abcd Successful");
}
@Test (groups ={"regression"})
populace void xyza(){
System.out.println("Xyza Successful");
}
@Test (groups ={"regression"})
populace void asdf(){
System.out.println("Asdf Successful");
}
}
------------
12) Give an illustration for Data Driven Testing?
If yous desire piece of employment amongst excel, as well as thus download tertiary political party jolt files
Ex: jxl
public cast DataDriven {
@Test (dataProvider="testdata")
populace void Addition(String val1, String val2, String val3){
int a = Integer.parseInt(val1);
int b = Integer.parseInt(val2);
int c = Integer.parseInt(val3);
int trial = a + b + c;
System.out.println(result);
}
@DataProvider(name="testdata")
populace Object [] [] readExcel() throws BiffException, IOException {
File f = novel File("C:/Users/gcreddy/Desktop/Input.xls");
Workbook w = Workbook.getWorkbook(f);
Sheet sec = w.getSheet(0);
int rows = s.getRows();
int columns = s.getColumns();
//System.out.println(rows);
//System.out.println(columns);
String Inputdata [] [] = novel String [rows] [columns];
for (int i = 0; i<rows; i++){
for (int j = 0; j<columns; j++){
Cell c = s.getCell(j, i);
Inputdata [i] [j] = c.getContents();
//System.out.println(Inputdata[i][j]);
}
}
provide Inputdata;
}
}
