# TestNG-Based UI Testing Framework for [COMPANY] in the [INDUSTRY] Sector

## Framework Overview

This framework is designed to help students strengthen their automation testing skills with practical examples and configuration. It includes the following features:

- **TestNG Annotations**: Utilizes TestNG annotations such as @BeforeMethod, @AfterMethod, @Test, and @DataProvider for structured test case management.
- **Parallel Testing**: Supports parallel test execution to improve test execution time and efficiency.
- **Cross-Browser Testing**: Enables testing across different browsers to ensure compatibility and robustness.
- **Logging with Log4j2**: Implements Log4j2 for comprehensive logging, making it easier to debug and track test execution.
- **Structured Reporting**: Generates detailed test reports for better analysis and reporting.

## Practical Examples

### Example 1: TestNG Annotations

```java
public class TestNGAnnotationsExample {
    @BeforeMethod
    public void setUp() {
        System.out.println("Setting up the test environment");
    }
    
    @Test
    public void testLogin() {
        System.out.println("Executing login test");
    }
    
    @AfterMethod
    public void tearDown() {
        System.out.println("Cleaning up the test environment");
    }
}
```

### Example 2: Parallel Testing

```java
public class ParallelTestingExample {
    @Test(threadPoolSize = 3, invocationCount = 5, timeOut = 1000)
    public void parallelTest() {
        System.out.println("Executing parallel test");
    }
}
```

## Configuration Details

### TestNG XML Configuration

```xml
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Test Suite" parallel="tests" thread-count="2">
    <test name="Test 1">
        <classes>
            <class name="TestNGAnnotationsExample"/>
        </classes>
    </test>
    <test name="Test 2">
        <classes>
            <class name="ParallelTestingExample"/>
        </classes>
    </test>
</suite>
```

### Log4j2 Configuration

```xml
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>
```
