### Question:
SalesforceDeleteMeta extends SalesforceStepMeta { public void getFields( RowMetaInterface r, String name, RowMetaInterface[] info, StepMeta nextStep, VariableSpace space, Repository repository, IMetaStore metaStore ) throws KettleStepException { } SalesforceDeleteMeta(); boolean isRollbackAllChangesOnError(); void setRollbackAllChangesOnError( boolean rollbackAllChangesOnError ); void setDeleteField( String DeleteField ); String getDeleteField(); void setBatchSize( String value ); String getBatchSize(); int getBatchSizeInt(); void loadXML( Node stepnode, List<DatabaseMeta> databases, IMetaStore metaStore ); Object clone(); String getXML(); void setDefault(); void getFields( RowMetaInterface r, String name, RowMetaInterface[] info, StepMeta nextStep,
    VariableSpace space, Repository repository, IMetaStore metaStore ); void readRep( Repository rep, IMetaStore metaStore, ObjectId id_step, List<DatabaseMeta> databases ); void saveRep( Repository rep, IMetaStore metaStore, ObjectId id_transformation, ObjectId id_step ); void check( List<CheckResultInterface> remarks, TransMeta transMeta, StepMeta stepMeta,
    RowMetaInterface prev, String[] input, String[] output, RowMetaInterface info, VariableSpace space,
    Repository repository, IMetaStore metaStore ); StepInterface getStep( StepMeta stepMeta, StepDataInterface stepDataInterface, int cnr,
    TransMeta transMeta, Trans trans ); StepDataInterface getStepData(); boolean supportsErrorHandling();  }### Answer:
@Test public void testGetFields() throws KettleStepException { SalesforceDeleteMeta meta = new SalesforceDeleteMeta(); meta.setDefault(); RowMetaInterface r = new RowMeta(); meta.getFields( r, "thisStep", null, null, new Variables(), null, null ); assertEquals( 0, r.size() ); r.clear(); r.addValueMeta( new ValueMetaString( "testString" ) ); meta.getFields( r, "thisStep", null, null, new Variables(), null, null ); assertEquals( 1, r.size() ); assertEquals( ValueMetaInterface.TYPE_STRING, r.getValueMeta( 0 ).getType() ); assertEquals( "testString", r.getValueMeta( 0 ).getName() ); }
