Hello,
I'm running some tests against a database and verifying that data inserts
are getting rolled back. I'm doing this with a ProcessTestFixture that 1)
counts rows in several tables, 2) does some work that should get rolled
back, 3) count rows in the same tables. To make the test more maintainable,
I use a CombinatorialTest against a Factory that returns table names.
I get the following exception on the last test, and if I remove that test, I
get the exception on the first test. I'm wondering if the framework doesn't
allow parameters in TestSequence tests?
Message: Parameter count mismatch.

Here is, approximately, the relevant part of my code:
[ProcessTestFixture]
public class TestEnvironmentRollbackTests
{
private Dictionary<string, int> _counts = new Dictionary<string,
int>();
[Factory(typeof(string))]
public IEnumerable<string> Tables()
{
yield return "Company";
yield return "User";
yield return "Product";
}
[CombinatorialTest]
[TestSequence(0)]
public void PreCount([UsingFactories("Tables")] string table)
{
_counts[table] = Util.CountTableRows(table);
}
[Test]
[TestSequence(1)]
public void DoStuff()
{
// do stuff
}
[CombinatorialTest]
[TestSequence(2)]
public void PostCount([UsingFactories("Tables")] string table)
{
Assert.AreEqual(_counts[table], Util.CountTableRows(table));
}
}
Thanks for any help,
Todd
