How to use OR task condition in azure devops using parameters

Question

parameters:
- name: agents
  displayName: Agent
  type: string
  default: test111
- name: tests
  displayName: “Hello test”
  type: string
  default:
    '"Hello World"'
- name: configuration_key
  displayName: Special Parameter Keyword
  type: string
  default: ""

jobs:
- job: tesst1
  strategy:
    matrix: ${{ parameters.execution_matrix }}
  variables:
    - name: 'TEST_S'
      value: ${{ parameters.tests }}
    - name: 'configuration_key'
      value: ${{ parameters.configuration_key }}
      displayName: App test
  timeoutInMinutes: 600
  pool:
    name: System_test
    
- task: DownloadPipelineArtifact@2
    inputs:
      source: 'specific'
      project: ‘Test APP’
      buildType: 'current'
      artifactName: ‘App Installer'
      pipeline: 001
      runVersion: 'latestFromBranch'
      runBranch: 'refs/heads/develop'
      targetPath: '$(Build.SourcesDirectory)/'
    displayName: 'Get Artifacts'
    condition: or( eq(‘{{parameters.agents}}', ‘test111’), eq(‘{{parameters.agents}}’, ‘test’222) )

Added the complete code. Default value will be test111. Just need to verify the condition and execute the tasks.

  Note: If i use only one condition then its working like below.
  
  eq('$ {{parameters.agents}}', 'test111') 

Either of any one agent is matched, then condition should be allow to execute tasks.

This approach should work. As parameters are populated before the compile time, you should assign this value into a variable in order to use it on the condition step.

trigger:
- none

pr: none 

    parameters:
    - name: image
      displayName: Pool Image
      type: string
      default: ubuntu-latest
      values:
      - windows-latest
      - ubuntu-latest
      - macOS-latest
    
    pool:
      vmImage: ubuntu-latest
    
    variables:
    - name: myvar
      value: ${{ parameters.image}}
    steps:
    
    - task: PowerShell@2
      inputs:
        targetType: 'inline'
        script: |
          # Write your PowerShell commands here.
          
          Write-Host "Hello World"
      condition: or( eq(variables.myvar, 'ubuntu-latest'), eq(variables.myvar, 'windows-latest') )

As the default value is evaluated correctly on the condition, the powershell will run.
