Junit Parameterization without private properties

**This is more of a query than an issue and I’m very Naive to Junit

I’m working on a Test Automation project which is based on Junit + Selenium. I would be needing a lot of test data for each of the scenario.

I’ve maintained a csv file to store the data, where in I’m reading the csv data and then mapping the header columns to the records values as a list of object.

Is it possible for Junit Parameterized tests running without the private properties? because,

1. There would be so many fields in the csv file and it would be a tedious job to create private properties for each of the test data.
2. The getRecords() method will return the data only as a object row mappings and it is not appropriate to define some private property for this row data.

import org.junit.Before; import org.junit.jupiter.api.Test; import org.junit.runner.RunWith; import org.junit.runners.Parameterized; import org.junit.runners.Parameterized.Parameters; import org.apache.commons.csv.CSVFormat; import org.apache.commons.csv.CSVParser; import org.apache.commons.csv.CSVRecord;

@Parameters
public static Collection getRecords(final String filename) throws IOException {
    Reader in = new InputStreamReader(new FileInputStream(new File(filename)));
    CSVParser csvParser = CSVParser.parse(in,CSVFormat.RFC4180.withFirstRecordAsHeader());
    Map<String, Integer> csvHeaderMapRaw = csvParser.getHeaderMap();
    HashMap<Integer, String> csvHeaderMapRawTailored = new HashMap<>();
    int counter = 0;
    for (String key : csvHeaderMapRaw.keySet()) {
    	System.out.println(key);
    	csvHeaderMapRawTailored.put(counter++,key);
    }
    Iterable<CSVRecord> records = csvParser.getRecords();
    LinkedHashMap<String, String> recordDataMap = new LinkedHashMap<>();
    LinkedHashMap<Long, Object> finalRecordDataMap = new LinkedHashMap<>();
    for (CSVRecord record : records) {
    	for(int valueIndex=0;valueIndex<csvHeaderMapRaw.size();valueIndex++){
    		recordDataMap.put(csvHeaderMapRawTailored.get(valueIndex), record.get(valueIndex));
    	}
    	finalRecordDataMap.put(record.getRecordNumber(), recordDataMap.clone());
    }
    List<Object> list = new ArrayList<Object>(finalRecordDataMap.values());
    System.out.println("The Records DataMap is: "+Arrays.asList(list));
    return Arrays.asList(list);
}

@Test
public void dataStream() {
	try {
		String fileName = "C:\\testData.csv";
		getRecords(fileName).toString();
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	
}

@dileepguntamadugu To be honest, it’s not clear if your question is about using JUnit (which does not care about “private properties”) or designing classes for the test data.

@Tibor17 Thank you. As i said earlier junit is new to me and didn’t ever try the dataprovider, i’ll give it a try and analyze as to how it will work on my project.
