hc_characterdataindexsizeerrsubstringnegativeoffset

public final class hc_characterdataindexsizeerrsubstringnegativeoffset extends org.w3c.domts.DOMTestCase
The "substringData(offset,count)" method raises an INDEX_SIZE_ERR DOMException if the specified offset is negative. Retrieve the character data of the last child of the first employee and invoke its "substringData(offset,count) method with offset=-5 and count=3. It should raise the desired exception since the offset is negative.
