C. Add TestNG to Your Project

• Plain Java (no build tool):
  • Right-click your project → Build Path → Add Libraries… → choose TestNG
• Maven: add to your pom.xml:

<dependency>

  <groupId>org.testng</groupId>

  <artifactId>testng</artifactId>

  <version>7.7.0</version> <!-- or latest -->

  <scope>test</scope>

</dependency>

then Project → Maven → Update Project

• Gradle: add to build.gradle:

dependencies {

  testImplementation 'org.testng:testng:7.7.0'

}

test {

  useTestNG()

}

2. Installing TestNG in IntelliJ IDEA

A. Enable/Install the TestNG Plugin

1. File → Settings (⌘, on macOS) → Plugins
2. Search for “TestNG”
3. If not installed, click Install; otherwise ensure it’s Enabled
4. Restart IDEA if prompted

Note: IntelliJ Ultimate bundles TestNG support by default. In Community Edition you may need the plugin.

B. Add TestNG to Your Project

• Maven: same pom.xml snippet as above; then Maven → Reimport
• Gradle: same build.gradle snippet; then Reload Gradle Project
• Plain Java:
  1. File → Project Structure → Libraries

  3. Apply and close

C. Creating a TestNG Run Configuration

1. Run → Edit Configurations…
2. Click + → TestNG
3. Give it a name (e.g. “All Tests”); choose Suite, Package, Class, or Method
4. If using an XML suite, point Suite to your testng.xml
5. Apply and Run

3. Verify Your Setup

1. Create a simple TestNG class:

import org.testng.annotations.Test;

public class HelloTest {

  @Test

  public void hello() {

    System.out.println("TestNG is working!");

  }

}

2. Right-click the class → Run ‘HelloTest’ (Eclipse) or click the green ▶ (IntelliJ).

3. You should see TestNG results in the console / TestNG Results view.

With those steps you’ll have TestNG installed, added to your project’s classpath, and ready to write & run your Selenium (or any) tests!
