Object
- DataTestCase

```
public abstract class DataTestCase
extends Object
```
A set of constructs and utility methods used to test the data module.
By isolating a common set of SimpleFeatures, SimpleFeatureTypes and Filters we are able to reduce the amount of overhead in setting up new tests.
This code has been made part of the public geotools.jar to provide a starting point for test cases involving Data constructs.
