How to get the current invocation count in TestNG?

TestNG supports multi-invocation of a test method, i.e., a @Test method can be invoked multiple times sequentially or in parallel. If we want to run single @Test 10 times at a single thread, then invocationCount can be used.

To invoke a method multiple times, the keyword invocationCount = is required. For example −

@Test(invocationCount = 10)

In this example, the @Test method will execute for 10 times each on a single thread.

In this article, we will illustrate how to get the current invocation count.

Approach/Algorithm to solve this problem

• Step 1 − Create a TestNG class, NewTestngClass.

• Step 2 − Write two @Test methods in the class NewTestngClass as shown in the programming code section below. Add invocationCount=10

• Step 3 − Create the testNG.xml as given below to run the TestNG classes.

• Step 4 − Now, run the testNG.xml or directly testNG class in IDE or compile and run it using command line.

• Step 5 − In the output, the user can see a total of 1 thread running sequentially for all invocations of @Test.

Example

Use the following code for the commonTestNG class, NewTestngClass −

src/ NewTestngClass.java

import org.testng.ITestContext;
import org.testng.annotations.*;
public class NewTestngClass {
   @Test(invocationCount = 10)
   public void testcase1(ITestContext testContext){
      System.out.println("Running testcase 1");
      int currentCount = testContext.getAllTestMethods()[0].getCurrentInvocationCount();
      System.out.println("Executing count: " + currentCount);
   }
   @Test(invocationCount = 10)
   public void testcase2(ITestContext testContext){
      System.out.println("Running testcase 2");
      int currentCount = testContext.getAllTestMethods()[1].getCurrentInvocationCount();
      System.out.println("Executing count: " + currentCount);
   }
}

testng.xml

This is a configuration file that is used to organize and run the TestNG test cases. It is very handy when limited tests are needed to execute rather than the full suite.
