Class DataTestCase

java.lang.Object
  junit.framework.Assert

All Implemented Interfaces:

junit.framework.Test

Direct Known Subclasses:

AbstractDataStoreTest

public class DataTestCase

extends junit.framework.TestCase

A set of constructs and utility methods used to test the data module.

By isolating a commong set of Features, FeatureTypes and Filters we are able to reduce the amount of overhead in setting up new tests.

We have also special cased assertEquals(Geometry, Geometry) to work around not working as expected.

This code has been made part of the public to provide a starting point for test cases involving Data constructs.

To Do:

It should be possible to move this class in the module.

Constructor Detail

DataTestCase

public DataTestCase(java.lang.String name)

Creates a default test case with the given name.

Method Detail

setUp

protected void setUp()
              throws java.lang.Exception

Invoked before a test is run. The default implementation invokes dataSetUp().

Throws:

java.lang.Exception

dataSetUp

protected void dataSetUp()
                  throws java.lang.Exception

Loads the data.

Throws:

java.lang.Exception

setUp()

tearDown

protected void tearDown()
                 throws java.lang.Exception

Set all data references to , allowing garbage collection. This method is automatically invoked after each test.

Throws:

java.lang.Exception

line

public com.vividsolutions.jts.geom.LineString line(int[] xy)

Creates a line from the specified (x,y) coordinates. The coordinates are stored in a flat array.

lines

public com.vividsolutions.jts.geom.MultiLineString lines(int[][] xy)

Creates a multiline from the specified (x,y) coordinates.

polygon

public com.vividsolutions.jts.geom.Polygon polygon(int[] xy)

Creates a polygon from the specified (x,y) coordinates. The coordinates are stored in a flat array.

polygon

public com.vividsolutions.jts.geom.Polygon polygon(int[] xy,
                                                   int[][] holes)

Creates a line from the specified (x,y) coordinates and an arbitrary amount of holes.

ring

public com.vividsolutions.jts.geom.LinearRing ring(int[] xy)

Creates a ring from the specified (x,y) coordinates. The coordinates are stored in a flat array.

assertEquals

protected void assertEquals(com.vividsolutions.jts.geom.Geometry expected,
                            com.vividsolutions.jts.geom.Geometry actual)

Compares two geometries for equality.
