### Question:
SalesforceConnection { public String[] getFields( String objectName ) throws KettleException { return getFields( getObjectFields( objectName ) ); } SalesforceConnection( LogChannelInterface logInterface, String url, String username, String password ); boolean isRollbackAllChangesOnError(); @Deprecated void rollbackAllChangesOnError( boolean value ); void setRollbackAllChangesOnError( boolean value ); boolean isQueryAll(); @Deprecated void queryAll( boolean value ); void setQueryAll( boolean value ); void setCalendar( int recordsFilter, GregorianCalendar startDate, GregorianCalendar endDate ); void setSQL( String sql ); void setFieldsList( String fieldsList ); void setModule( String module ); String getURL(); String getSQL(); Date getServerTimestamp(); String getModule(); QueryResult getQueryResult(); PartnerConnection createBinding( ConnectorConfig config ); PartnerConnection getBinding(); void setTimeOut( int timeout ); int getTimeOut(); boolean isUsingCompression(); void setUsingCompression( boolean useCompression ); String getUsername(); void setUsername( String value ); String getPassword(); void setPassword( String value ); void connect(); void query( boolean specifyQuery ); void close(); int getQueryResultSize(); int getRecordsCount(); SalesforceRecordValue getRecord( int recordIndex ); String getRecordValue( SObject con, String fieldname ); XmlObject[] getElements(); boolean queryMore(); String[] getAllAvailableObjects( boolean OnlyQueryableObjects ); Field[] getObjectFields( String objectName ); Field[] getObjectFields( String objectName, boolean excludeNonUpdatableFields ); String[] getFields( String objectName ); String[] getFields( String objectName, boolean excludeNonUpdatableFields ); String[] getFields( Field[] fields ); String[] getFields( Field[] fields, boolean excludeNonUpdatableFields ); UpsertResult[] upsert( String upsertField, SObject[] sfBuffer ); SaveResult[] insert( SObject[] sfBuffer ); SaveResult[] update( SObject[] sfBuffer ); DeleteResult[] delete( String[] id ); static XmlObject createMessageElement( String name, Object value, boolean useExternalKey ); static XmlObject fromTemplateElement( String name, Object value, boolean setValue ); static XmlObject[] getChildren( SObject object );  }### Answer:
@Test public void getFieldsTest() throws KettleException { String name = "name"; SalesforceConnection conn = new SalesforceConnection( null, "http: Field[] fields = new Field[ 1 ]; Field field = new Field(); field.setRelationshipName( "Parent" ); field.setName( name ); fields[ 0 ] = field; String[] names = conn.getFields( fields ); Assert.assertEquals( name, names[ 0 ] ); }
