HashMapFixture does not provide a working query() (well ... it just barely works :)). It should be overridden and return an array of HashMap.
The keys of the HashMap should correspond to the names of a column.
super class: RowFixture RowFixture provides the validation for each row for a fixed number of columns.
sub class: Select Select provides the validation of a database table on the DefaultConnection
    public Object[] query() throws Exception {
        Vector rows = new Vector();
        HashMap row1 = new HashMap();
        java.util.Enumeration columns;
        columns = propertyNames();
        while(columns.hasMoreElements()){
            row1.put(columns.nextElement(), "Some Value ...");
        }
        rows.add(row1);
        
        HashMap row2 = new HashMap();
        columns = propertyNames();
        while(columns.hasMoreElements()){
            row2.put(columns.nextElement(), "Another Value ...");
        }
        rows.add(row2);
        return rows.toArray();
    }
A column will defaults to using a String.equals(). This can be overridden by registering a property as a different class.
class MyProperties extends HashMapFixture{
    MyProperties(){  
       propertyTypes.put("BirthDate", java.util.Date.class);
