  • Blog Post: Are You Reporting Inaccurate Performance Numbers with VS 2008?

    There’s a hidden problem with VS 2008 load testing that you need be aware if you are running tests locally (as opposed to using a controller and agents). If you purchase and run a load agent, load agents run on all cores and all CPUs on the machine. However, when running locally VS limits load...

  • Blog Post: Back from PDC

    I spent last week in LA at the PDC. The conference was mainly focused on the new technologies Microsoft is working on bringing to market, such as Windows 7 and Azure. We also introduced the features in our next VSTS release, which customers were super-excited to see. It's always great to step back at...
  • Blog Post: Event ordering in Web Tests

    Web tests have a number of extensibility points before and after a request. What order do they run in? The hooks are: WebTestPlugin.PreRequest WebTestRequestPlugin.PreRequest ExtractionRule.Extract ValidationRule.Validate Here is a sequence diagram that shows what order things fire: There is no guaranteed...
  • Blog Post: JW post on MS Testing - my observations

    Check out James's recent post with the eye-catching title “if Microsoft is so good at testing, why does your software suck?” I have another angle on this, which I saw first hand with our Whidbey release. It goes to some of the themes I refer to in my So you want to automate your test cases? post. We...

  • Blog Post: New templates for plugins and rules

    Inspired by templates developed by Dennis Bass of the services test labs, I added new item templates to the codeplex.com\TeamTestPlugins project.

    dynaTrace just completed a nice integration with VSTS web, unit and load tests that enables them to do end-to-end tracing of performance. In addition to getting overall performance numbers, they have a feature called PurePath that let's you trace, down to a given web test request, what calls that request...
  • Blog Post: Masking a 404 error in a dependent request

    There are times when your web test may fail with a 404 error in a dependent request (like a css file or gif), but you may not actually care about this error. For example, it may be something that doesn't really impact the layout or content of the page. Or you might file a bug and temporarily want to...

    Check out the stats for the WCF load test tool on codeplex. The tool is approaching 2000 downloads! Kudos again to Rob Jarratt, who wrote this tool.

  • Blog Post: Updated Links to Info

    I updated my Links to Info on Web and Load Tests post with new links. The last update was in March, so it was due. I also moved some links into a separate table that are specific to 2005. Some of the 2005 context still applies to 2008, so I left that in the main table. Most of the links are to new content...
  • Blog Post: Web test support for random text extraction in SP1

    In SP1 we added a new Random property on the Extract Text rule. This simple property enables some really powerful scenarios. The best example is to randomly select a link that is the result of a query. This works nicely if search result urls are uniform and pass the selection as a query string parameter...

  • Blog Post: SQL Load Test vs. Read80Trace and OStress

    A reader asked about my post on SQL Load testing , and why someone would want to use that vs. Read80Trace and OStress . OSTRESS does straight record/playback of a trace file, but does not allow you to do experiments on mixing up commands, nor does it allow you to parameterize your tests. For example...
  • Blog Post: New rules published to codeplex

    I've published a new project to http://codeplex.com/teamtestplugins . This project is based on VS 2008. A summer intern we have from Duke, Herodotos Herodotou, has developed a nice set of rules we did not have before. All of the rules have to do with the inner text of a tag. For example, for a select...
  • Blog Post: Dependent request filter for Web tests

    A pretty common need when you are testing your web application is to filter out certain types of dependent requests. For example, if a page you are testing has an ad in it from an external site, you may not want to hit that site in your load tests. Here is a simple WebTestPlugin that will allow you to...

  • Blog Post: Catching errors as they happen: WebTest ValidateResponseUrl

    In VS 2008, we added a new Validation Rule ValidateResponseUrl. In VS 2005, a very common problem was that a page would redirect to the error page, but the web test engine did not automatically recognize this as an error. Then downstream in the playback another page would fail, usually with "hidden...
