Azure Continuous Integration is a game-changer for developers, allowing them to automate the build, test, and deployment of their code. By integrating Azure CI into their workflow, developers can significantly reduce the time and effort required to get their code into production.

With Azure CI, you can automate the process of building and testing your code, catching errors and bugs early on. This helps ensure that your code is stable and reliable before it reaches production.

By automating the build and deployment process, Azure CI also helps reduce the risk of human error, which can lead to costly mistakes and downtime.

A unique perspective: Azure Continuous Deployment

What is CI?

Continuous integration is a practice that helps catch bugs early in the development cycle, making them less expensive to fix.

Automated tests are executed as part of the continuous integration process, which is crucial for ensuring quality.

The Build service in Azure DevOps Server helps set up and manage continuous integration for your applications.

Continuous integration systems produce artifacts that are fed into release processes to drive continuous deployments.

Setting Up CI

To set up CI, you'll need to have an Azure DevOps organization. This will serve as the central hub for all your project management and version control needs.

If you don't already have an organization, you can easily create one. Having a clear and organized workspace will make it much easier to manage your projects and collaborate with team members.

Once you have your organization set up, you'll need to store your source code in a version control system. This is where you'll keep track of all the changes made to your codebase.

You can use Azure Pipelines to manage your CI process, but first, you need to install all operating system dependencies using the Command line tools.

Here are the prerequisites you need to meet:

  • Have an Azure DevOps organization
  • Store your source code in a version control system

CI Configurations

CI configurations are a crucial part of Azure Continuous Integration. They allow you to install all operating system dependencies from the command line tools.

You can use Azure Pipelines to set up CI configurations that automatically build and validate changes in your version control repository, such as Azure Repos Git, GitHub, and TFVC.

In a CI pipeline, build completion triggers can be set up to rebuild and revalidate a service when an upstream service changes, making it easier to manage dependencies.

Version Control Systems

Version control systems are a crucial part of CI configurations, and Azure Pipelines requires your source code to be in one.

Azure Pipelines supports several forms of version control, including Azure Repos Git, GitHub, and TFVC.

You can set up Azure Pipelines to automatically build and validate any changes you push to your version control repository.

This automation is a game-changer for teams, allowing them to catch errors early and avoid last-minute surprises.

Languages and Applications

When you're working on a CI configuration, you need to consider the languages and applications you're using. Azure Pipelines offers tasks to build, test, and deploy Node.js, Python, Java, PHP, Ruby, C#, C++, Go, XCode, .NET, Android, and iOS applications.

These tasks allow you to run your apps in parallel on different operating systems, including Linux, macOS, and Windows. You can also run tests in many testing frameworks and services.

You can use tasks to run command line, PowerShell, or shell scripts in your automation. This gives you a lot of flexibility in how you design your CI pipeline.

CI Configurations

CI configurations are essential for automating software development processes. You can use Command line tools to install all operating system dependencies in CI.

To set up CI configurations, you'll need to integrate your version control system. Azure Pipelines requires your source code to be in a version control system, which can be Azure Repos Git, GitHub, or TFVC.

Command line tools can be used to install all operating system dependencies in CI, making it easier to manage your development environment. This can save you time and effort in the long run.

Azure Pipelines supports automatic builds and validation of changes pushed to your version control repository. This means you can focus on writing code rather than manually managing dependencies.

Via Containers

Using containers in your CI configuration can be a game-changer for keeping your host environment clean and consistent.

Running jobs in a container with GitHub Actions is a great way to avoid polluting the host environment with dependencies.

This approach ensures that each job has a consistent environment, which is especially useful for tasks like screenshots and visual regression testing across different operating systems.

Containerization also helps you maintain a clean and organized workspace.

Uploading Playwright-Report Folder is a crucial step in your CI Configuration. This involves uploading the playwright-report folder with Azure Pipelines.

To make the pipeline run fail if any of the playwright tests fail, you can use Azure Pipelines. The pipeline will fail if any of the playwright tests fail.

You can also integrate the test results with Azure DevOps by using the PublishTestResults task. This task needs to be configured accordingly via playwright.config.ts.

Note that the JUnit reporter needs to be configured in playwright.config.ts for this to work.

Package Formats

Package formats are essential for external users to consume packages, and you can integrate package management into your CI/CD pipelines to make it happen.

You can publish NuGet, npm, Maven, or Python packages as artifacts to the built-in Azure Pipelines package management repository, or any other package management repository you choose.

Azure Pipelines allows you to publish packages to the built-in package management repository.

A CI pipeline is a series of automated processes that build, test, and deploy code changes to ensure they meet quality and deployment standards.

To create a CI pipeline, you'll need an Azure DevOps account and a repository containing your application code, typically hosted on a version control system like Git.

You can access Azure DevOps by logging in to your account and navigating to your project's Pipelines page, where you can create a new pipeline.

For a Windows or macOS agent, no additional configuration is required, just install Playwright and run your tests, but for Linux agents, you can use our Docker container with Azure Pipelines support running containerized jobs.

Azure Pipelines provides a quick, easy, and safe way to automate building your projects with consistent and quality code that's readily available to users.

Here are some benefits of using Azure Pipelines:

  • Works with any language or platform.
  • Deploys to different types of targets at the same time.
  • Integrates with Azure deployments.
  • Builds on Windows, Linux, or Mac machines.
  • Integrates with GitHub.
  • Works with open-source projects.

To configure your pipeline, you can choose a template that matches your application's technology stack, or use the "Starter pipeline" option and define your pipeline using YAML or the visual designer.

You can also define build and test stages, configure deployment stages for each target environment, and configure triggers to automatically start the pipeline when changes are pushed to specific branches or pull requests are created.

In addition, you can add variables and secrets to store your pipeline's configuration settings and securely store sensitive information.

Here are the 11 steps to create an Azure CICD pipeline:

  1. Access Azure DevOps: Log in to your Azure DevOps account.
  2. Create a New Pipeline: Navigate to your project. Go to “Pipelines” from the left sidebar. Click on the “New Pipeline” button.
  3. Select a Repository: Choose the repository that contains your application code. Select the appropriate source control system (e.g., Git).
  4. Configure Pipeline Settings: Choose a template that matches your application’s technology stack (e.g., ASP.NET, Node.js, Python).
  5. Define Build and Test Stages: Configure the build stage to compile your code, restore dependencies, and generate build artefacts.
  6. Define Deployment Stages: Set up deployment stages for each target environment (e.g., development, staging, production).
  7. Configure Triggers: Define triggers to automatically start the pipeline when changes are pushed to specific branches, pull requests are created, or on a schedule.
  8. Add Variables and Secrets: Define variables to store your pipeline’s configuration settings. Securely store sensitive information, such as API keys or connection strings.
  9. Review and Save: Review the pipeline configuration to ensure everything is set up correctly. Save and commit the pipeline configuration to your repository.
  10. Run and Monitor the Pipeline: Trigger the pipeline manually or let it be triggered automatically based on the defined triggers.
  11. Customise and Iterate: As your application and requirements evolve, you can customize and iterate on your pipeline by adding more stages, tasks, or adjustments to the configuration.
