Run Selenium Java Tests In Azure DevOps

Run Jobs Sequentially

Understand how to set up Azure DevOps pipelines to execute Selenium Java tests sequentially based on priority levels. Learn to use jobs, strategies, and matrix configurations in YAML to control test execution order and customize artifact names for logs and screenshots.

We'll cover the following...

So far, we have executed all tests in a single job.

The Priority variable is passed to the goals of the Maven task so the tests with the specific priority are executed:

goals: 'clean test -Dgroups=$(Priority)'

Let’s say that we want to execute tests sequentially by priority:

  • First, the High priority tests should run.
  • Then, the Medium priority should run.
  • Finally, the Low priority ones should run.

How to execute jobs sequentially

To execute jobs sequentially, we need to change the pipeline code as follows so that it uses jobs and strategies:

YAML
trigger:
- master
jobs:
- job:
  pool:
    vmImage: 'ubuntu-latest'
  strategy:
    matrix:
      Tests_High: 
        TestsPriority: "High"
      Tests_Medium:
        TestsPriority: "Medium"
      Tests_Low:
        TestsPriority: "Low"
    maxParallel: 1  
    
  steps:
   - task: Bash@3
     displayName: "create browser variable"
     inputs:
       targetType: 'inline'
       script: |            
         export BROWSER=$(BROWSER)
   - task: Maven@3
     inputs:
      mavenPomFile: 'pom.xml'
      mavenOptions: '-Xmx3072m'
      javaHomeOption: 'JDKVersion'
      jdkVersionOption: '1.8'
      jdkArchitectureOption: 'x64'
      publishJUnitResults: true
      testResultsFiles: '**/surefire-reports/TEST-*.xml'
      goals: 'clean test -Dgroups=$(TestsPriority)'
   - task: PublishBuildArtifacts@1
     displayName: 'Publish Log File as Artifact'
     inputs:         
       PathtoPublish: $(System.DefaultWorkingDirectory)/target/logs
       ArtifactName: 'logs_$(TestsPriority)'
   - task: PublishBuildArtifacts@1
     displayName: 'Publish Screenshots as Artifact'
     inputs:         
       PathtoPublish: $(System.DefaultWorkingDirectory)/target/screenshots
       ArtifactName: 'screenshots_$(TestsPriority)'

The pipeline has a jobs section, which can include one job or more (line 4). ...
