First Ensure that your Azure Pipeline agent is running on the test node itself

Then 

Use either the BatchScript task or the CmdLine task

example for BatchScript

# ... your pipeline stages ...

- stage: Test
  jobs:
  - job: RunBatchFile
    pool:
      vmImage: 'windows-latest' # Or specify your agent pool that runs on the test node
    steps:
    - task: BatchScript@1
      inputs:
        filename: '\\<test-node-name>\<shared-folder-path>\<your-batch-file>.bat'  # Replace with the actual path
        # arguments: '...'  # Optional: Add arguments for your batch file

and 

example for CmdLine

# ... your pipeline stages ...

- stage: Test
  jobs:
  - job: RunBatchFile
    pool:
      vmImage: 'windows-latest' 
    steps:
    - task: CmdLine@2
      inputs:
        script: 'call \\<test-node-name>\<shared-folder-path>\<your-batch-file>.bat' 
        # add any additional arguments to the script if necessary
