Integrating LambdaTest with CI/CD Pipelines

Estimated reading: 3 minutes 112 views

Continuous Integration and Continuous Deployment (CI/CD) play a crucial role in ensuring faster, more reliable software releases. As a QA tester or developer, integrating LambdaTest with a CI/CD pipeline allows you to automate your cross-browser testing process, ensuring your web applications function seamlessly across different environments. In this guide, I will walk you through setting up a CI/CD pipeline for a Selenium TestNG project hosted on GitHub, enabling automated test execution on every push to the main branch and scheduling daily runs at 8:00 AM EST.

Setting Up GitHub Actions for LambdaTest

Creating a GitHub Actions Workflow

GitHub Actions allows you to define automated workflows using YAML configuration files. To begin, navigate to your lambdatest-selenium-kicksapp repository and create a new file at:

GitHub LambdaTest Setup

.github/workflows/lambdatest-ci.yml

Now, add the following content to configure your workflow:

YAML File Configuration

name: LambdaTest CI/CD

on:
  push:
    branches:
      - main
  schedule:
    - cron: '0 13 * * *' # Runs daily at 8:00 AM EST (UTC +0:00 is 13:00)
  workflow_dispatch: # Enables manual trigger from the GitHub UI

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout Repository
      uses: actions/checkout@v3

    - name: Set up JDK 17
      uses: actions/setup-java@v3
      with:
        distribution: 'temurin'
        java-version: '17'

    - name: Cache Maven Dependencies
      uses: actions/cache@v3
      with:
        path: ~/.m2
        key: ${{ runner.os }}-maven-${{ hashFiles('**/pom.xml') }}
        restore-keys: |
          ${{ runner.os }}-maven-

    - name: Run Selenium Tests on LambdaTest
      run: |
        mvn test -D suite=testng.xml
      env:
        LT_USERNAME: ${{ secrets.LT_USERNAME }}
        LT_ACCESS_KEY: ${{ secrets.LT_ACCESS_KEY }}

Understanding the Workflow

Triggers: The pipeline runs on every push to the main branch and daily at 8:00 AM EST.
Java Setup: Ensures that Java 17 is installed for running Selenium tests.
Maven Dependency Caching: Speeds up builds by caching dependencies.
Installation & Execution: Installs dependencies and runs Maven-based Selenium tests on LambdaTest.
Test Reports Upload: Stores test results as artifacts for later review.

Configuring Secrets

To securely store your LambdaTest credentials, follow these steps:

Go to your GitHub Repository.
Navigate to Settings > Secrets and variables > Actions.
Click New repository secret.
Add the following secrets:
LT_USERNAME: Your LambdaTest username.
LT_ACCESS_KEY: Your LambdaTest access key.

These credentials allow the CI pipeline to authenticate with LambdaTest and execute tests on the cloud platform.

Commit and Push the Workflow File

After creating the .github/workflows/lambdatest-ci.yml file in your project, commit and push the changes to the main branch. This triggers the workflow and executes tests on LambdaTest.

Debugging Common Issues

If you encounter issues:

Ensure your LambdaTest credentials are correct.
Verify that the testng.xml file is correctly defined in your project.
Check GitHub Actions logs for any dependency or configuration errors.
Confirm that LambdaTest is accessible and your Selenium tests run successfully locally.

Conclusion

Integrating LambdaTest with a CI/CD pipeline enhances automated web app testing, improving efficiency and reliability. By setting up GitHub Actions, you ensure continuous validation of your application’s functionality. This approach streamlines testing workflows, reduces manual intervention, and accelerates the development cycle.
