TestNG Testing Skill

When to Use

Use this skill when you need generates TestNG tests in Java with groups, data providers, parallel execution, XML suite configuration, and listeners. Use when user mentions "TestNG", "@DataProvider", "testng.xml", "groups". Triggers on: "TestNG", "@DataProvider", "testng.xml", "TestNG suite", "parallel tests Java".

Core Patterns

Basic Test with Groups

import org.testng.annotations.*;
import org.testng.Assert;

public class LoginTest {
    @BeforeMethod
    public void setUp() { /* setup */ }

    @Test(groups = "smoke")
    public void testLoginSuccess() {
        Assert.assertTrue(loginService.login("[e-mail]", "password123"));
    }

    @Test(groups = "regression", dependsOnMethods = "testLoginSuccess")
    public void testAccessDashboard() {
        Assert.assertNotNull(dashboard.getContent());
    }

    @Test(expectedExceptions = AuthenticationException.class)
    public void testLoginInvalidPassword() {
        loginService.login("[e-mail]", "wrong");
    }

    @AfterMethod
    public void tearDown() { /* cleanup */ }
}

Data Providers

@DataProvider(name = "loginData")
public Object[][] loginData() {
      [][] {
        {, , },
        {, , },
        {, , },
    };
}


   {
    Assert.assertEquals(loginService.login(email, password), expected);
}
