CI/CD Pipeline Flow

The CI/CD pipeline typically includes the following stages:
1. Code Commit
2. Jenkins Trigger
3. Checkout Code
4. Build with Maven
5. Run TestNG Tests
6. Generate Allure Reports
7. Archive Artifacts
8. Deploy to Staging/Prod

Sample TestNG Test (Java)

import org.testng.annotations.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class SampleTest {
    @Test
    public void openGoogle() {
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.google.com");
        assert driver.getTitle().contains("Google");
        driver.quit();
    }
}

Maven pom.xml Snippet

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.0.0</version>
            <configuration>
                <suiteXmlFiles>
                    <suiteXmlFile>testng.xml</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
</build>

Jenkins Pipeline (Declarative)

pipeline {
    agent any

    tools {
        maven 'Maven 3.8.1'
        jdk 'JDK 11'
    }

    stages {
        stage('Checkout') {
            steps {
                git 'https://github.com/your-repo/automation-tests.git'
            }
        }

        stage('Build') {
            steps {
                sh 'mvn clean install'
            }
        }

        stage('Test') {
            steps {
                sh 'mvn test'
            }
        }

        stage('Allure Report') {
            steps {
                allure includeProperties: false, jdk: '', results: [[path: 'target/allure-results']]
            }
        }

        stage('Archive Artifacts') {
            steps {
                archiveArtifacts artifacts: '**/target/*.jar', fingerprint: true
            }
        }
    }

    post {
        always {
            junit 'target/surefire-reports/*.xml'
        }
    }
}

Best Practices

• Fail Fast: Run unit tests early to catch issues quickly.
• Parallel Testing: Use Selenium Grid or cloud services to speed up execution.
• Environment Isolation: Use Docker containers for consistent test environments.
• Versioned Artifacts: Store builds in Nexus or Artifactory for traceability.
• Notifications: Integrate Slack, Teams, or email for build/test alerts.
