GitHub Actions gives you the flexibility to build an automated software development lifecycle workflow. You can automate your workflows to run load tests on Azure. Azure Load Testing is a fully managed load testing service that enables you to generate high-scale load. The service will simulate traffic for your applications, regardless of where they're hosted. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity.

The definition of this GitHub Action is in action.yml.

• Azure Login Login with your Azure Credentials for Authentication. Once login is done, the next set of Azure Actions in the workflow can re-use the same session within the job.

For using any credentials like Azure Service Principal in your workflow, add them as secrets in the GitHub Repository and then refer them in the workflow.

1. Download Azure CLI from here, run az login to login with your Azure Credentials.

2. Run Azure CLI command to create an Azure Service Principal for RBAC:

       az ad sp create-for-rbac --name "my-load-test-cicd" --role contributor \
                            --scopes /subscriptions/<subscription-id> \
                            --sdk-auth
   
       # Replace {subscription-id}, {resource-group} with the subscription, resource group details of the Azure Load Testing resource
       # The command should output a JSON object similar to this:
   
     {
       "clientId": "<GUID>",
       "clientSecret": "<GUID>",
       "subscriptionId": "<GUID>",
       "tenantId": "<GUID>",
       (...)
     }

3. Paste the json response from above Azure CLI to your GitHub Repository > Settings > Secrets > Add a new secret > AZURE_CREDENTIALS

4. To authorize the service principal to access the Azure Load Testing service, assign the Load Test Contributor role to the service principal.

   First, retrieve the service principal object ID by running this Azure CLI command:

   az ad sp list --filter "displayname eq 'my-load-test-cicd'" -o table
   

   Next, assign the Load Test Contributor role to the service principal. Replace the placeholder text <sp-object-id> with the ObjectId value from the previous Azure CLI command. Also, replace the <subscription-name-or-id> with your Azure subscription ID.

   az role assignment create --assignee "<sp-object-id>" \
       --role "Load Test Contributor" \
       --subscription "<subscription-name-or-id>"
   

5. Now in the workflow file in your branch: .github/workflows/workflow.yml replace the secret in Azure login action with your secret (Refer to the example below)

   - uses: azure/login@v1
     with:
       creds: ${{ secrets.AZURE_CREDENTIALS }}

This section describes the Azure Load Testing GitHub action. You can use this action by referencing azure/load-testing@v1 action in your workflow. The action runs on Windows, Linux, and Mac runners.

You can use the following parameters to configure the GitHub action.

The following YAML code snippet describes how to use the action in a GitHub Actions workflow.

- name: 'Azure Load Testing'
  uses: azure/load-testing@v1
  with:
    loadTestConfigFile: '< YAML File path>'
    loadTestResource: '<name of the load test resource>'
    resourceGroup: '<name of the resource group of your load test resource>' 
    secrets: |
      [
          {
          "name": "<Name of the secret>",
          "value": "${{ secrets.MY_SECRET1 }}",
          },
          {
          "name": "<Name of the secret>",
          "value": "${{ secrets.MY_SECRET2 }}",
          }
      ]
    env: |
      [
          {
          "name": "<Name of the variable>",
          "value": "<Value of the variable>",
          },
          {
          "name": "<Name of the variable>",
          "value": "<Value of the variable>",
          }
      ]

The results files are exported to the folder “loadTest\results.zip”
