dataTypeFactory - an IDataTypeFactory, or null

Method Details

readDataSetFromClasspath

public static org.dbunit.dataset.IDataSet readDataSetFromClasspath(String dataSetDtdResourceName,
 String... dataSetResourceNames)
                                                            throws org.dbunit.dataset.DataSetException,
IOException

Reads XML data set files from the classpath resources pointed to by dataSetResourceNames, optionally validating using the DTD pointed to by dataSetDtdResourceName property.

The dataSetDtdResourceName parameter may be null, in which case no validation is performed.

Parameters:

dataSetDtdResourceName - the name of the resource containing the DTD for test data files, or null

dataSetResourceNames - the names of the resources containing test data

Returns:

the test data set

Throws:

org.dbunit.dataset.DataSetException - if some resource if malformed

IOException - if reading a resource failed

init

public void init()
          throws Exception

Initializes the test data before each test case.

Throws:

Exception - if something goes wrong

clean

public void clean()
           throws Exception

Cleans the database from test data after each test case.

Throws:

Exception - if something goes wrong

setSetUpOperation

public void setSetUpOperation(org.dbunit.operation.DatabaseOperation setUpOperation)

Change the operation performed before executing each test.

The default setup operation is DatabaseOperation.CLEAN_INSERT.

Parameters:

setUpOperation - the new setup operation to use

setTearDownOperation

public void setTearDownOperation(org.dbunit.operation.DatabaseOperation tearDownOperation)

Change the operation performed after executing each test.

The default is to perform no cleanup after the test.

Parameters:
