To add in data to be tested for a table, make sure to add a Test-inititalData.xml file into your src/test/resources:
<?xml version='1.0' encoding='UTF-8'?>
<dataset>
<table_name_here first_column_name="value1" second_column_name="value2"/>
<table_name_here first_column_name="value3" second_column_name="value4"/>
</dataset>
(NOTE: the src/test/resources folder should automatically come under the heading 'Other Test Resources' – if not, right click your project in Netbeans and choose Reload POM)
In addition, make sure your table mapping .hbm.xml file is defined in the test-hibernate.cfg.xml file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
">
<hibernate-configuration>
<session-factory>
<mapping resource="TESTTABLEMAPPINGFILE.hbm.xml" />
<mapping resource="ANOTHERMAPPINGFILE.hbm.xml" />
</session-factory>
</hibernate-configuration>
(NOTE: test-hibernate.cfg.xml should also come in src/test/resources under 'Other Test Resources' – if not, create your own test-hibernate.cfg.xml)
