### Question:
CapturingTransformationRows { public static void main( String[] args ) { try { KettleEnvironment.init(); } catch ( KettleException e ) { e.printStackTrace(); return; } instance = new CapturingTransformationRows(); instance.runTransformation( "etl/capturing_rows.ktr" ); }  static void main( String[] args ); List<Object[]> runTransformation( String filename ); static CapturingTransformationRows instance; public List<Object[]> capturedRows; public RowMetaInterface rowStructure; }### Answer:
@Test public void testRows() { CapturingTransformationRows.main( new String[ 0 ] ); List<Object[]> rows = CapturingTransformationRows.instance.capturedRows; assertFalse( rows.isEmpty() ); }
