Understanding Azure DevOps

Before we make pipelines, let’s talk about some important things. Azure DevOps is a tool that helps development teams work well together. They can plan tasks, save their code in a version control system like Git, and handle builds and releases. A key feature of this tool is Azure DevOps pipelines. This service works with all major languages. It helps automate the stages of building, testing, and deploying your code projects.

In an Azure DevOps organization, you can create several projects. Each project comes with its own tools and services, like Azure Pipelines. This helps keep work organized. It also allows teams to collaborate better on software development projects.

The Role of Azure DevOps in CI/CD

Azure DevOps is crucial for continuous integration and continuous delivery. Continuous integration (CI) happens when code builds and tests itself on its own whenever a change happens in the version control system. This regular testing spots errors early. It helps prevent big issues and keeps the code stable.

With Azure DevOps pipelines, you can make build pipelines that allow access control. These pipelines get the newest code version from your repository. They will compile the code, run tests, and prepare artifacts for deployment. This process helps you have better visibility into what is happening.

Continuous delivery (CD) moves this process ahead. It automatically sends the build artifacts to different locations like staging or production. Azure DevOps helps make this smooth with release pipelines. These pipelines make sure that your app is deployed safely in various environments.

Using CI/CD with Azure DevOps helps companies release software more quickly. It also makes the code better and cuts down the time needed to add new features and updates.

Key Components of Azure DevOps Pipelines

Azure Pipelines has different parts to help automate tasks. The first part is agents. Agents are the machines that run jobs in your pipelines. There are two types of agents in Azure DevOps pipelines. You can use Microsoft-hosted agents. These come with a ready-to-use environment and default settings. Alternatively, you can select self-hosted agents. This choice gives you more control over how things work and the runtime features.

Jobs help you set up steps that run on an agent. A step is a specific task, like compiling code, running tests, or setting up deployments. You can use many ready-made tasks. You can also make your tasks using scripts and command-line tools. Pipelines are divided into stages. Each stage groups jobs smartly. For example, a pipeline could have stages for building, testing, and deployment. This simple setup makes complex workflows easier to handle. It also helps you read and maintain your work better.

Preparing for Your First Pipeline

Before you start building your first Azure DevOps pipeline, make sure you are ready. You will need a code repository on sites like GitHub, Azure Repos, or Bitbucket. It’s also good to know some simple YAML syntax. This knowledge will help you create a simple example for setting up the tasks and structure of your pipeline definition.

Step-by-Step Guide to Creating Your Pipeline

It’s easy to build your pipeline. First, we will show you how it is set up. Next, we will help you connect to your source control. After that, we will guide you in setting up triggers for automatic builds. With Azure’s simple platform and our clear instructions, you will have a strong pipeline ready in no time.

These steps will help you understand the basics. As you learn, you can explore some advanced choices.

1. Prepare Your Test Project

Ensure that your test project is ready for automated testing. This could be a unit test project, integration test, or UI tests (like Selenium or Playwright).

• For .NET projects: Use a test framework like MSTest, NUnit, or xUnit.
• For Java projects: Use JUnit or TestNG.
• For Node.js projects: Use frameworks like Mocha, Jasmine, or Jest.

2. Create a New Pipeline in Azure DevOps

• Go to your Azure DevOps organization and project.
• Navigate to Pipelines from the left menu.
• Click on Create Pipeline.
• Choose the repository where your code is stored (GitHub, Azure Repos, etc.).
• Select a pipeline template (for example, you can select a template for the technology you’re using like .NET, Node.js, etc.).
• Click Continue to proceed to the pipeline editing page.

3. Configure Your Pipeline for Testing

You’ll need to define a pipeline YAML file or use the classic editor. Here’s an example of how to run tests using the YAML-based pipeline.

Example: For a Java Maven Cucumber Project

trigger:
  branches:
    include:
      - main

pool:
  name: AgentPoolName  # Name of the agent pool
  demands:
    - Agent.Name -equals <<AgentName>>  # Specify the exact agent by its name

Steps:
  # Step 1: Clean the Maven project
  - script: |
      mvn clean
    displayName: Clean the Maven Project

  # Step 2: Compile and Run Maven tests
  - script: |
      mvn test -Drunner=testrunner -Denv=QA -Duser=superAdmin@qa.com
    displayName: Run Maven Tests

Explanation:

Step 1: Clean the Maven Project

This Maven command removes all the files generated by the previous builds (like compiled classes, JAR files, logs, etc.) in the target directory. It ensures a clean environment for the next build process.

Step 2: Compile and Run Maven Tests

This command compiles the test code and executes the unit and integration tests in the project.

Note: Before starting the execution, ensure that the agent is running and displayed as Online.

• Go to Azure DevOps:li

• Open your Azure DevOps portal.

• From the left-hand side, click on Project settings (located at the bottom left).
• Under the Pipelines section, select Agent Pools.

• In the Agent Pools section, locate and open the LocalAgentPool.
• Check the list of agents associated with the pool.
• Ensure that the agent you added appears in the list with a status of Online.

4. Publish Test Results

In the YAML above, the PublishTestResults task is included to publish the results to the pipeline interface. This will show you test results in the Azure DevOps portal after the pipeline run.

Here’s an example of the task for different test frameworks:

• For Allure Report, able to generate the Allure report in Azure DevOps.
• For NUnit or MSTest, you’ll typically publish *.xml test result files as well.

Step 1: Generate Allure Report

 - script: |
      allure generate allure-results --clean
    displayName: Generate Allure Report
    condition: succeededOrFailed()

This will mark the pipeline run as failed if any test fails.

Explanation: Generate and Open Allure Report

Generates an Allure report from the test results stored in the allure-results directory and to view test execution results.

5. Set up Continuous Integration (CI) Triggers

To run the pipeline automatically on every commit, make sure to configure your pipeline’s trigger:

trigger:
  branches:
    include:
      - main

This will trigger the pipeline to run for any changes pushed to the main branch.

6. Run the Pipeline

Once you’ve defined your pipeline, save and run it. Azure DevOps will automatically run the build and execute the automated tests. You can monitor the progress and see the results in the Pipelines section of your Azure DevOps project.

7. View Test Results

After the pipeline completes, navigate to the Tests tab in the pipeline run. Here, you’ll find a detailed view of your test results, including passed, failed, and skipped tests.

• If your tests have been configured to publish results, you’ll see a summary of the tests.
• You can also download the detailed test logs or check the console output of the pipeline run.

Enhancing Your Pipeline

As you learn the basics, check out the different options in Azure DevOps. They can help improve your pipeline. You can add artifact repositories to organize your build outputs. It’s important to set up good testing stages. Also, don’t miss continuous deployment (CD). It can help you automate your releases.

Improving all the time is important. It’s good to see how well your pipeline is working. Look for ways to make it better. Use new features as Azure DevOps grows.

Implementing Continuous Integration (CI)

Continuous Integration (CI) is very important in an Azure DevOps Pipeline. It helps mix code changes smoothly. When developers automate the CI process, they can easily combine code into a shared repository. This practice starts automated builds and runs tests to see if the changes are good. Because of this, teams can find bugs early and get quick feedback. This improves the quality of the code. It also helps teamwork. Using Azure Pipelines for CI helps teams improve their workflows and deliver software more effectively.

Automating Deployments with Continuous Deployment (CD)

One key feature of Azure DevOps is its ability to automate deployments through continuous deployment (CD). With CD pipelines in Azure DevOps, teams can make it easier to deploy applications. This leads to faster and more efficient delivery of applications. CD automatically sends code changes to production. This reduces the need for manual work. It lets teams release software more often and reliably. This boosts productivity and flexibility while developing. Using CD in Azure DevOps helps teams automate their deployment process. It allows them to focus on providing value for users.

Conclusion

Creating a good Azure DevOps pipeline is very important. It makes your CI/CD processes easier. First, you should learn the main parts. Next, set up your account and configure your project to get started. A clear guide will help you define your build pipeline. It will also help you connect to source control and run builds well.
