Building and Testing Applications with CodePipeline


AWS CodePipeline is a fully managed continuous integration and continuous delivery service that helps you automate your software release processes. It enables you to build, test, and deploy your applications with ease. In this tutorial, we will explore how to use CodePipeline to build and test your applications efficiently.


  • An AWS account with access to AWS CodePipeline.
  • An application code repository hosted on a supported version control system (e.g., AWS CodeCommit, GitHub).
  • An AWS CodeBuild project configured to build your application.
  • A testing framework and test suites for your application.

Step-by-Step Tutorial

Step 1: Set Up AWS CodePipeline

1. Go to the AWS Management Console and open the CodePipeline service.

2. Click on "Create pipeline" to start creating a new pipeline.

3. Provide a name for your pipeline and click "Next".

4. Select your source provider (e.g., AWS CodeCommit, GitHub) and configure the connection to your application code repository.

5. Choose the branch you want to monitor for changes and click "Next".

6. Add a build stage and configure it to use your AWS CodeBuild project. Specify the build commands and settings required to build your application.

7. Add a test stage and configure it to run your testing framework. Specify the test commands and settings required to execute your test suites.

8. Add any additional stages for deployment, approval, or other actions as per your application's deployment requirements.

9. Review the pipeline configuration and click "Create pipeline" to create your pipeline.

Step 2: Triggering Pipeline Execution

Once your pipeline is set up, it will automatically trigger whenever changes are pushed to the monitored branch in your application code repository. You can also manually trigger a pipeline execution from the AWS CodePipeline console by selecting your pipeline and clicking "Release change".

Common Mistakes to Avoid

  • Not configuring the build stage correctly, resulting in build failures.
  • Skipping or insufficiently testing the application, leading to potential bugs in production.
  • Not properly configuring the testing stage, causing test failures or incomplete coverage.

Frequently Asked Questions (FAQs)

  1. Q: Can I use multiple build and test stages in a single pipeline?
    A: Yes, you can configure multiple build and test stages in a CodePipeline to support different environments or architectures.
  2. Q: Can I run different types of tests, such as unit tests and integration tests, in the test stage?
    A: Yes, the test stage can execute various types of tests based on your application's testing framework and requirements.
  3. Q: How can I handle build or test failures in CodePipeline?
    A: CodePipeline provides visibility into build and test execution status. You can configure actions, notifications, or manual approvals based on the outcome of these stages.
  4. Q: Can I integrate third-party testing tools with CodePipeline?
    A: Yes, CodePipeline can integrate with various third-party testing tools and services to enhance your testing capabilities.
  5. Q: Is it possible to parallelize build and test stages in CodePipeline?
    A: Yes, CodePipeline supports parallel execution of stages, allowing you to optimize the speed and efficiency of your build and test processes.


AWS CodePipeline simplifies the process of building and testing applications by providing a fully managed continuous integration and continuous delivery service. By following the steps outlined in this tutorial, you can set up a pipeline that automatically builds and tests your applications whenever changes are pushed to your code repository. Avoiding common mistakes and considering the FAQs provided will help you ensure smooth build and test processes, leading to high-quality releases and improved application reliability.
