Sauce Labs with Azure DevOps

Azure DevOps (formerly Visual Studio Team Services or VSTS) is a Microsoft product that provides version control, reporting, requirements management, project management, automated builds, testing and release management capabilities.

What You'll Need

• A Sauce Labs account (Log in or sign up for a free trial license)
• Your Sauce Labs Username and Access Key
• An existing Azure DevOps pipeline

Using Azure DevOps

Follow the instructions below to integrate Sauce Labs testing into your Azure pipeline.

1. Sign in to your Azure DevOps organization and go to your project.
2. Go to Pipelines > New pipeline.
3. Link the new pipeline to your repository (see Azure Pipelines Documentation for guidance). You'll likely need to provide permissions for Azure Pipelines to access your repository management system.
4. Set your Sauce Labs username and access key as environment variables in your pipeline by clicking Pipeline > Variables, and then pasting the values of your username and access key.
5. In your source code, you'll need to reference the Sauce Labs environment variables that you set in Azure DevOps. For example:

C# example

var sauceUserName = Environment.GetEnvironmentVariable("SAUCE_USERNAME");
var sauceAccessKey = Environment.GetEnvironmentVariable("SAUCE_ACCESS_KEY");

6. Create a YAML file using one of the templates below. You'll also need to reference your Sauce Labs environment variables here.

   Node.js

   trigger:
   - main
   
   pool:
     vmImage: ubuntu-latest
   
   # Multiple pipelines can re-use variables
   # that are stored in a variable group
   variables:
   - group: sauce-labs-variables
   
   steps:
   - task: NodeTool@0
     inputs:
       versionSpec: '14.x'
     displayName: 'Install Node.js'
   
   - script: |
   # Navigate to the working directory
      cd ./webdriverio/webdriver/examples/w3c/
   # Install node packages
      npm install
   # Run tests on Sauce and enables a high level of logging for CI
      npm run test.saucelabs.us -- --logLevel "debug"
   |
   
    env:
      # Reads the value from 'sauceUsername' in Azure DevOps and
      # stores it into SAUCE_USERNAME env variable
      SAUCE_USERNAME: $(sauceUsername)
      SAUCE_ACCESS_KEY: $(sauceAccessKey)
    displayName: 'install and run WebdriverIO tests in Sauce Labs'

   Java

   # Build your Java project and run tests with Apache Maven.
   trigger:
   – main
   pr:
   – main
   
   pool:
     vmImage: 'ubuntu-latest'
   
   # Sets the environment variables for the pipeline.
   # We create a variable sauce_user and assign it a value of $(SAUCE_USERNAME), which comes from the Azure DevOps.
   variables:
   – name: sauce_user
     value: $(SAUCE_USERNAME)
   – name: sauce_key
     value: $(SAUCE_ACCESS_KEY)
   
   steps:
   – bash: echo $SAUCE_USER
   – bash: echo $SAUCE_KEY
   
   # Builds and runs the tests in the Maven project.
   – task: Maven@3
