If you are using unit test framework like JUnit or TestNg Then the methods mentioned under annotations like @Test ,@Before and so on are independent itself. Their execution order is as per preferance in that framework itself. Main method not required here.

So in your case if you have done code using these methods using any TestNG or JUnit then have to use like following -

class Myclass
{

      @Before
      public void methodA()
     {
           // Your code
     }

     @Test
     public void methodB()
     {
         // your code
     }
    @After
    public void methodC
   {
          // your code
   }
}

And Run your class like Run As > TestNG Test if you are using TestNG framework

No i am not using TestNG or JUnit and both of these code snippets are from different packages. the script is already written i just need to invoke this script programmatically from a different package

NarendraR Over a year ago

then import that package where you want to access and do access the method by creating object of that class. in your example 1. import Script.java class package in Main.java class's package. 2. Create an object of Script class under main method and then access method of Script class using that object. 3. Run Main.java class

Thats the problem i have around 20 methods in Script.java and they are ordered using before , test, after so i don't want to call every method from the main.java. i just wanted to know that is there a way so that i can run complete script.java from main.java

Whishky, It sounds like your "script" was written with a testing framework in mind, but it is not clear which one. Perhaps you can find out by looking at the import statements. Then, to run it, as it was written as a testing module, you need to invoke the testing framework from the main.java file and have the testing framework load and run the script. Doing something else will likely not give you the same results as the script intended.

Annotations in java needs a package like junit ,testNg or cucumber - jvm where

@Test ,@Before ,@After

could find a way to be run.So you cannot find an answer in java to run them as these annotations are not part of Java.

I think only way to run testNG based script is to create a suite of testNG.xml file and do the execution of suite in main class.Try this code

    List<String> suitesList = new ArrayList<String>();
    TestListener listener = new TestListener();
    TestNG testng = new TestNG();
    testng.setOutputDirectory("outputfoldername");
    suitesList.add("testng.xml");
    testng.setTestSuites(suitesList);
    testng.addListener(listener);
    testng.run();
