Re: [dbunit-developer] Fwd: Annotations for DBUnit

[Roberto Lo G. <rlo...@gm...>]

I found the work on Annotations very useful but my idea on annotations is a
little bit different, may be a bunch of code can be more expressive than a
long email....

// Initialization dataset
@TestDataSet(value = "invoice.xml", format = Format.FLAT_XML)
public class UsageExample {

@TestConnection(url = "jdbc:", type = TestConnection.Type.JDBC, username =
"sa", password = "", setUp = DatabaseOperation.CLEAN_INSERT, tearDown =
DatabaseOperation.NONE)
 public Connection connection;

@Test
@TestDataSet.Composite({
 @TestDataSet("http://www.dbunit.org/users.xml"),
 @TestDataSet(value = "file://test/orders.xml", format = Format.FLAT_XML) })
 public void multipleURLDataSetWithSameFormat(DataSet expected) {
DataSet actual = connection.createDataSet("SOMETHING");
 assertEquals(expected, actual);
}
}


Notice the dataset parameter which will be injected with the dataset... A
parameter level annotation could be better allowing for method level
initialization dataset AND method level expected dataset, but I think it
will clutter the code...

I think a field level annotation to provide the connection is required, we
can go for a static field too, or for a class level annotation plus an
annotated field/method... But we must have no more than one connection per
test class or we will not be able to choose which one use to load the
initialization dataset...
