Why TestNG?
Testframework influnced by JUnit
- Annotations
- Assertions
- Attributes (priority, dependsOnMethods, and dependsOnGroups)
- Data-driven testing
- Cross-browser testing
Install TestNG
in your IDE

Basic Test-Annotation
@Test followed by a Method to write a test:
public class Basics {
@Test
public void Demo(){
System.out.println("hello");
}
@Test
public void Second(){....
}
multiple Testcases in one Class with each @Test Annotation
Create an XML
(IntelliJ XML Plugin):
xml Hierachy: Test Cuit -> Test Folder (Shell)-> Test Cases
- to compose different Testexecutions
- exclude/include specific tests in the execution
- RegEx Wildcard
.*(use Name Conventions!)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
<test name="basics">
<classes>
<class name="TestNG.Basics"/>
<class name="TestNG.day3"/>
</classes>
</test>
<test name="later in the day">
<classes>
<class name="TestNG.day2">
<methods>
<include name="SecondTest"/>
</methods>
</class>
</classes>
</test>
<test name="later">
<classes>
<class name="TestNG.day3" >
<methods>
<exclude name="Demo*"/>
</methods>
</class>
</classes>
</test>
</suite>
Refere to packages
e.g. for Regressiontests
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Packages">
<test name="basics">
<packages>
<package name="TestNG"/>
</packages>
</test>
</suite>
Before/ After - Annotations
Before: First Execution to wipe System clean, delete Data or execute Testdata in Database. API: BaseURl put in Test, Mobile: start appium automation server
After: Last Execution to delete Cookies, stop processes, read reports, APIs: close connections
xml-Level
@BeforeTest Before Folder (<test> .... </test>)
@AfterTest After Folder (<test> .... </test>)
Scope: Folder in which it is defined
@BeforeSuite Before everthing which is in xml file (<suite> .... </suite>)
@AfterSuite After everthing which is in xml file (<suite> .... </suite>)
Scope: xml
Class-Level
@BeforeMethod Before each and every Method (e.g. Delete Cookies, REST API- Authenticate each + every time)
@AfterMethod After each and every Method
Scope: class only(runs several times for each method)
write the annotation in any class in the folder (<test> .... </test>)
@BeforeClass
@AfterClass
public class Basics {
@Test
public void Demo(){ System.out.println("hello"); }
@BeforeTest
public void prerequisite() {
System.out.println("first execution");
}
@AfterTest
public void lastExecution(){
System.out.println("execute last");
}
}
run specific Tests with groups
to run a specific subset of tests spread through the classes
e.g. Smoke Tests
<suite name="Suite">
<test name="basics">
<groups>
<run>
<include name="smoke"/>
</run>
</groups>
<classes>
<class name="TestNG.Basics"/>
<class name="TestNG.day2"/>
<class name="TestNG.day3"/>
</classes>
</test>
</suite>
exclude is possible too
with a little help of attributes
Order Methods
TestNG executes the tests in alphabetic Order
Tweak order with ... @Test(dependsOnMethods = {"Demo", "Demo2"})
Skip Test
if you already reported a Bug and can go on
@Test(enabled = false)
TimeOut
in ms
@Test(timeOut = 4000)
Parametrizing
in XML file (global environment variables)
in xml
<suite name="Suite">
<parameter name="URL" value="qaclickacademy.com" />
<parameter name="APIKey/usrname" value="123" />
<test name="basics">
<parameter name="URL" value="basic.com" />
<classes>
<class name="TestNG.Basics"/>
<class name="TestNG.day3"/>
</classes>
</test>
<test name="later in the day">
<parameter name="URL" value="day.com" />
<classes>
<class name="TestNG.day2">
<methods>
<include name="SecondTest"/>
</methods>
</class>
</classes>
</test>
you determine which URL is passed to which class with where it is put in the xml
in java-class
@Parameters("URL", "APIKey/usrname")
@Test
public void Demo(String urlname, String key){ System.out.println(urlname + key); }
with DataProvider Annotation
@Test(dataProvider = "getData")
public void SecondTest(String username, String password){
System.out.println(username);
System.out.println(password);
}
@DataProvider
public Object[][] getData() {
Object[][] data = new Object[3][2];
//1st set
data[0][0] = "firstusername";
data[0][1] = "password";
//2nd set
data[1][0] = "secondusername";
data[1][1] = "password";
//3rd set
data[2][0] = "thirdusername";
data[2][1] = "password";
return data;
}
ITestListener Interface
import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;
public class Listeners implements ITestListener {
@Override
public void onTestSuccess(ITestResult result) {
System.out.println("Successfully passed - as you can hopefully see.");
}
@Override
public void onTestFailure(ITestResult result) {
System.out.println("Successfully failed the test " + result.getName());
}
}
add to XML file
<suite name="Suite">
<listeners>
<listener class-name="TestNG.Listeners"/>
</listeners>
<parameter name="URL" value="qaclickacademy.com" />
Run Tests parallel
e.g. for Performance Testing
in xml File
<suite name="Suite" parallel="tests" thread-count="2">
which means 2 tests run at a time
for mobile testing you have to have multiply devices, for API fine
or <test parallel="classes" thread-count="2" >
Reporting
then you'll find a testoutput Folder with a index.html, you can generate the report with
