Why don’t we use the main method in TestNG?

As an experienced tutor registered on UrbanPro.com, it's crucial to shed light on the role of the main method in TestNG and why it's not the primary entry point for test execution. Understanding this distinction is fundamental for automation testing professionals seeking comprehensive knowledge. Let's delve into the reasons behind not using the main method in TestNG.

1. The Main Method in Java Applications

- Overview:

• Explanation:
  • In traditional Java applications, the main method serves as the entry point for program execution. It is where the Java Virtual Machine (JVM) starts executing the application.

- Key Characteristics:

• Points to Highlight:
  • Main method signature: public static void main(String[] args).
  • Execution begins from the main method.

2. TestNG and Test Execution Lifecycle

- Overview:

• Explanation:
  • TestNG, being a testing framework, operates differently from standalone Java applications. It follows a specific test execution lifecycle that doesn't align with the traditional main method approach.

- Key Characteristics:

• Points to Highlight:
  • TestNG relies on annotations and methods for test configuration and execution.
  • Annotations like @Test are used to denote test methods.

3. Why Not Use the Main Method in TestNG?

- 1. TestNG Annotations for Test Configuration:

• Explanation:
  • TestNG provides a set of annotations such as @Test, @BeforeSuite, @AfterSuite, etc., to configure and control the test execution lifecycle.

- 2. Framework-Managed Execution:

• Explanation:
  • TestNG manages the execution of tests based on its annotations and configuration, removing the need for a traditional main method.

- 3. Parallel Execution and Configuration Flexibility:

• Explanation:
  • TestNG allows parallel execution, and its configuration flexibility is better leveraged through annotations, providing a more dynamic approach than a fixed main method.

4. Learning TestNG - Coaching for Automation Testing Professionals:
