### Question:
StringOperations extends BaseTransform<StringOperationsMeta, StringOperationsData> implements ITransform<StringOperationsMeta, StringOperationsData> { public boolean init() { boolean rCode = true; if ( super.init() ) { return rCode; } return false; } StringOperations( TransformMeta transformMeta, StringOperationsMeta meta, StringOperationsData data, int copyNr, PipelineMeta pipelineMeta,
                           Pipeline pipeline ); boolean processRow(); boolean init(); void dispose();  }### Answer:
@Test @Ignore public void testProcessBinaryInput() throws HopException { StringOperations transform = new StringOperations( smh.transformMeta, smh.iTransformMeta, smh.iTransformData, 0, smh.pipelineMeta, smh.pipeline ); transform.addRowSetToInputRowSets( mockInputRowSet() ); IRowSet outputRowSet = new QueueRowSet(); transform.addRowSetToOutputRowSets( outputRowSet ); StringOperationsMeta meta = mockTransformMeta(); StringOperationsData data = mockTransformData(); transform.init(); boolean processResult; do { processResult = transform.init(); } while ( processResult ); Assert.assertTrue( outputRowSet.isDone() ); Assert.assertTrue( "Unexpected output", verifyOutput( new Object[][] { { "Value" } }, outputRowSet ) ); }
