How to execute a particular test method multiple times (say 5 times) in
TestNG?

We can execute a particular test method multiple times (say 5 times) with the help of the invocationCount helper attribute.

Example

@Test
public void PaymentDetails(){
   System.out.println("Payment details validation is successful”);
}
@Test(invocationCount=5)
public void LoginAdmin(){
   System.out.println("Login in admin is successful”);
}
@Test
public void LeaseDetails(){
   System.out.println("Lease details verification is successful”);
}

In the Java class file, the LoginAdmin() method with invocationCount set to 5 will result in Login in admin is a successful message to be printed five times on the console.
