Checked running test pipeline with zoom package from the integrations repository

Before (everything false):

  <file path="packages/zoom/data_stream/webhook/elasticsearch/ingest_pipeline/zoomroom.yml">
    <lineToCover lineNumber="4" covered="false"></lineToCover>
    <lineToCover lineNumber="5" covered="false"></lineToCover>
    <lineToCover lineNumber="6" covered="false"></lineToCover>
    <lineToCover lineNumber="7" covered="false"></lineToCover>
    <lineToCover lineNumber="8" covered="false"></lineToCover>
    <lineToCover lineNumber="9" covered="false"></lineToCover>
    <lineToCover lineNumber="10" covered="false"></lineToCover>
    <lineToCover lineNumber="11" covered="false"></lineToCover>
    <lineToCover lineNumber="12" covered="false"></lineToCover>
    <lineToCover lineNumber="13" covered="false"></lineToCover>
    <lineToCover lineNumber="14" covered="false"></lineToCover>
    <lineToCover lineNumber="15" covered="false"></lineToCover>
    <lineToCover lineNumber="16" covered="false"></lineToCover>
    <lineToCover lineNumber="17" covered="false"></lineToCover>
    <lineToCover lineNumber="18" covered="false"></lineToCover>
    <lineToCover lineNumber="19" covered="false"></lineToCover>
  </file>

After:

  <file path="packages/zoom/data_stream/webhook/elasticsearch/ingest_pipeline/zoomroom.yml">
    <lineToCover lineNumber="4" covered="true"></lineToCover>
    <lineToCover lineNumber="5" covered="true"></lineToCover>
    <lineToCover lineNumber="6" covered="true"></lineToCover>
    <lineToCover lineNumber="7" covered="true"></lineToCover>
    <lineToCover lineNumber="8" covered="true"></lineToCover>
    <lineToCover lineNumber="9" covered="true"></lineToCover>
    <lineToCover lineNumber="10" covered="true"></lineToCover>
    <lineToCover lineNumber="11" covered="true"></lineToCover>
    <lineToCover lineNumber="12" covered="false"></lineToCover>
    <lineToCover lineNumber="13" covered="false"></lineToCover>
    <lineToCover lineNumber="14" covered="false"></lineToCover>
    <lineToCover lineNumber="15" covered="false"></lineToCover>
    <lineToCover lineNumber="16" covered="true"></lineToCover>
    <lineToCover lineNumber="17" covered="true"></lineToCover>
    <lineToCover lineNumber="18" covered="true"></lineToCover>
    <lineToCover lineNumber="19" covered="true"></lineToCover>
  </file>

To compare, this is the result for that data stream using Cobertura:

        <class name="zoomroom" filename="packages/zoom/data_stream/webhook/elasticsearch/ingest_pipeline/zoomroom.yml" line-rate="0" branch-rate="0" complexity="0">
