What is BumbleBee?

Buzz BumbleBee is an automated test harness for evaluating XQuery engines and validating queries expressed in the XQuery language.

BumbleBee takes the pain and uncertainty out of learning and using XQuery. It starts by letting you immediately put several XQuery engines to the test so you know how they stack up against the XQuery specification. Then it lets you easily write your own tests to continually make sure your XQuery expressions produce reliable results when you upgrade your XQuery engine, try different engines, or otherwise make changes to your queries.

BumbleBee is all about push-button regression testing. Indeed, BumbleBee tests act as automated change detectors to eliminate costly XQuery debugging cycles. So minimize the risks of being an early XQuery adopter by letting BumbleBee buzz over your FLWOR expressions!

Why Use BumbleBee?

XQuery is quickly gaining traction as the standard language for querying and manipulating collections of XML data. Using XQuery, however, can be quite frustrating as you're faced with choosing from a variety of XQuery engines that support different versions and interpretations of the XQuery specification. And once you've selected the XQuery engine that's right for you, you'll want automated tests that check that the queries you write always produce the expected results.

BumbleBee takes the guesswork out of using XQuery. Out of the box, it includes a comprehensive suite of tests based on the XQuery specification. It also includes a set of adapters to several popular free and commercial XQuery engines. So, in one fell swoop, BumbleBee will run a healthy dose of compatibility tests against nearly any XQuery engine. You can even run all the compatibility tests against multiple XQuery engines to compare and contrast their results. Every test checks its own results and gives you an unambiguous pass or fail status. For every test that fails, the test report indicates what result was expected and what result the engine actually produced. The comparison logic smartly handles formatting and whitespace issues and the complex XQuery rules where non-deterministic results are allowed. No need to guess, just run the tests!

The compatibility tests distributed with BumbleBee are just the beginning. Once you've chosen an XQuery engine, you can start writing your own application-specific tests. Writing a new test is easy: you specify the query to be run and the expected result in a text file. And just like the compatibility tests, you can continually and automatically run all your custom tests against an XQuery engine.

Learning XQuery?

What if you're new to XQuery and just learning how to write good queries? With BumbleBee, learning XQuery has never been easier or more fun!

You simply start by writing a BumbleBee test that specifies the query result you wish you had. Think of it as the goal. Then in the BumbleBee test you write the query intended to produce the desired result. You continue to refine the query -- running the test after each change -- until the BumbleBee test passes. At every step along the way, by running the test BumbleBee will tell you what result the engine actually produced. Using that feedback as a guide throughout your pursuit for the best query, you'll know whether you're getting warmer or colder.

In the end (if there ever is one in learning) you'll have a collection of passing BumbleBee tests that you can refer back to and continually run. That is, you'll have real working examples of XQuery in action.
