DbFit is an extension to FIT/FitNesse that makes test-driven database development easy. Version 1.0 (2008-03-10) is a major cleanup release, finally bringing proper documentation for the library as well. Grab it from SourceForge.

Major updates

1. Support for in/out parameters in stored procedures.
2. Support for querying stored results
3. Support for SQL Server 2000 in .NET. Not as complete as Sql Server 2005, but should work in most cases.
4. Support for testing blank-padded fixed length CHAR types.
5. .NET version now compiled with FitNesse.NET 1.5
6. Proper documentation — finally. The documentation is available as PDF and FitNesse (included in the dbfit-complete package) and also online at FitNesse.Info.

Minor updates

1. Oracle date used as Timestamp to allow V8 compatibility switch to work
2. Stored procedure params no longer have to be listed in the same order as in db
3. GUID handler now just redirecting to standard GUID handler in .NET
4. OrderedQuery and StoreParameter fixtures for standalone mode
5. bugfix for transactions not getting rolled back in Java after tests in flow mode
6. bugfix for ntext and text field sizes in sql server
7. bugfix for fail[null] NullPointerException in Java
8. workaround for fail[null] bug in fitnesse.net 1.5
9. Acceptance tests now reorganised better.

Many thanks to Marisa Seal for her help with the documentation and Oscar Centeno for his help with Sql Server 2000 implementation.

A pre-release with this functionality is now available for testing.
- To use In/Out parameters, just define two columns for the same parameter. The one for OUT direction should have a question mark
- Order of parameters in the table is no longer important (it was in Java), so you should be able to put parameters in FitNesse pages in a different order then those in the database.

Here is an example:

|Execute procedure|MultiplyIO|
|factor|val|val?|
|10|5|50|
|2|8|16|

Introducing IN/OUT parameters required a huge change in the underlying parameter processing, please help by testing a pre-release and verifying that your old tests work with the new system as well.

SQL Server turned out to be especially tricky because there is no explicit IN/OUT flag on stored procedure parameters, and .NET driver does not expect all outputs to be simply declared as InputOutput, so there is an ugly workaround in the code to check whether an output parameter is also used for input. I do not expect any problems with this, but it’s best to double-check.

Get the binary builds for .NET and Java from SourceForge.
