Testing that all projects need
+1 Vote Up -0Vote Down

Today, I was reminded of a Jim Starkey quote on the Random Query Generator:

“The Colonoscopy of Database Software”
– Jim Starkey

If your project does not have something that you can adapt that quote to, odds are your testing is inadequate.

Get to know the Random Query Generator
Employee +2 Vote Up -0Vote Down

In the MySQL QA teams in Oracle we have been using a tool called the Random Query Generator (or "RQG" for short) for some time now. The main RQG testing effort has been on new server development, including regression testing. The recent MySQL 5.6 GA is a result of a couple of years of hard work, including a lot of RQG testing and bugfixing as a result of that.

I can easily say that the RQG has helped making MySQL 5.6 a better release than it would otherwise be. It is of course not our only testing tool, but there are plenty of bugs …

New home for Random Query Generator docs
Employee +0 Vote Up -0Vote Down

One of the tools we use to qualify MySQL Server is the Random Query Generator (RQG for short). This is an SQL generator (and more) to test database systems such as MySQL. I plan to post more on that later.

The RQG is an open source tool written in Perl, and is available on Launchpad. Up until now the RQG documentation has been part of the MySQL Forge wiki. As you may have seen from …

Of course, since I am a QA Engineer, I could not resist the urge to try to break it >:)  As my friend and former MySQL colleage, Kostja says, “QA Engineers are a unique breed…they like to push all the buttons” : )  I would say that the QA mindset goes a bit further than that, but it is something I will delve into in another post.  I will only say that there is a reason …

More on kewpie (the query probulator)
+0 Vote Up -0Vote Down

My presentation from the MySQL UC didn’t give a lot of detail on the actual tool I have hacked up, nor did it go into how to play with it / try it out.  I figured I should rectify that (at least one person seemed interested in trying it out <g>)

To begin with, you should have the random query generator installed (see the docs for handling that).  Besides being *the* cutting edge, production-ready testing tool in the open-source dbms world, it comes with a handy …

Crash-testing the innodb transaction log!
+0 Vote Up -0Vote Down

So, back when we released our first beta in September, one of the many responses was this

The comments about the reliability / durability of the log definitely struck me as testing we needed.

It’s taken a while (we had this GA thing we were working on…), but we finally have crash and recover testing of the innodb transaction log and the …
