Problem

Vector automatically splits an array passed to . into multiple events: . = [event1, event2, etc] will be output as 3 events from a transform.

I was writing a test for such a transform and I was expecting the test to check all events for matching the condition, but the test passed even if only one of the matched the check.

For example, if we have an array [{"itemPrice": 3000}, {"itemPrice": 5000}] and check assert!(.itemPrice == 5000) the test will pass.

Full configuration for this test is provided.

Configuration

[transforms.dummyTest]
  type   = "remap"
  inputs = ["dummy_source"]
  source = '''
  # . = [{"itemPrice": 3000}, {"itemPrice": 5000}]
  ., err = parse_json(.message)

  if ( err != null )
  {
    log("Error: {{ err }}", level: "error")
    abort
  }

  . = .events
  '''


[[tests]]
  # General
  name = "Dummy test" # required
  
  # Inputs
  [[tests.inputs]]
    insert_at = "dummyTest" # required
    type = "raw" # required
    value = '''
    {
      "events": [{
        "itemPrice": 3000
      },{
        "itemPrice": 5000
      }]
    }
    '''

  [[tests.outputs]]
    # General
    extract_from = "dummyTest" # required

    [[tests.outputs.conditions]]
    # Conditions
    type = "vrl" # optional, default
    source = '''
    assert!(.itemPrice == 5000)
    '''
