How to give Custom Method name in TestNG emailable report, in case when DataProvider is Used

Question

I am using Data Provider in and report is displaying the same method name in all the tests in TestNG report.

static String TC_Name;
@DataProvider(name="SampleTestData")
public Object[][] testData() {
    return new Object[][]{
        {"TestCase1","Description1",""},
        {"TestCase2","Description2",""},
        {"TestCase3","Description3",""},
        //{"TestCaseID_2","TC_Description","Negative",""},
    };
}


@Test(dataProvider="SampleTestData", alwaysRun = true,testName="SampleTest")
public void testCaseInitialization(String testcaseID,String testcaseName, String Temp) {
    Log.startTestCase(testcaseID + "_" + testcaseName);
    TC_Name= testcaseID;
}

Now the output i want I want is "TestCase(1-3)". But i am getting "testCaseInitialization" in report.

I have tried the below way of hacking the report.:

@AfterMethod(alwaysRun = true)
public void setResultTestName(ITestResult result) {
    try {
        BaseTestMethod baseTestMethod = (BaseTestMethod) result.getMethod();
        Field f = baseTestMethod.getClass().getSuperclass().getDeclaredField("m_methodName");
        f.setAccessible(true);
        f.set(baseTestMethod, TC_Name);
    } catch (Exception e) {
       // ErrorMessageHelper.getInstance().setErrorMessage(e);
        Reporter.log("Exception : " + e.getMessage());
    }
}

But this is giving me the "TestCase3" in all method names.

Can please anybody suggest , how else can I hack the report.

You can customize method name with @Test annotation method only, if you want to retrieve "TestCase(1-3)" then apply it to Test Method. Report invoke method name of @Test method.
