Here is a nice way to do use OpenCSV to do the mapping to POJO generically:

protected  List mapToCSV(String csvContent, Class mapToClass) {
    CsvToBean csvToBean = new CsvToBean();

    Map columnMapping = new HashMap<>();
    Arrays.stream(mapToClass.getDeclaredFields()).forEach(field -> {
        columnMapping.put(field.getName(), field.getName()); 
    });

    HeaderColumnNameTranslateMappingStrategy strategy = new HeaderColumnNameTranslateMappingStrategy();
    strategy.setType(mapToClass);
    strategy.setColumnMapping(columnMapping);

    CSVReader reader = new CSVReader(new StringReader(csvContent));
    return csvToBean.parse(strategy, reader);
}


public static class MyPojo {
    private String foo, bar;

    public void setFoo(String foo) {
        this.foo = foo;
    }

    public void setBar(String bar) {
        this.bar = bar;
    }
}

Then from your test you can use:

List list = mapToCSV(csvContent, MyPojo.class);
