    Data Driven Testing: What’s a Good Dataset Size?

    I thought I’d follow up that last post on Using Data Driven Testing Wisely with something specific around the size of the dataset for a data driven test (DDT). What’s a good size for a DDT? As with everything in software engineering/testing, the answer is “42.” That, or “It depends.” In all seriousness, the right size of a dataset for a carefully thought out scenario does indeed depend. My payroll algorithm in the last post was a simple test set. You may be working something much more complex relating to finance, rocket science, or environmental controls. Every situation’s different, but ...

    WaitForVisible Steps That Don't Wait

    Occasionally we get complaints that the WaitForVisible steps in Test Studio don't work correctly. Our response is "It's not our fault!"   Here's what I mean: the Visibility check relies on the Computed Style of the element as seen through the lens of the browser. Specifically we look at the Display property. Here's a video of me using the Google Developer tool to determine the visibility property of an HTML element. Display:none means element is not visible. So it might be that your browser of choice is not very good at determining the visibility factor. Personally I recommend that ...

    NYC Breakfast Event Update!

    I mentioned earlier that I’m going to be heading up a breakfast event on 1/29 in New York city at the Microsoft office. Due to some schedule changes we’ve had to tweak the first session. Instead of the SOLID talk previously scheduled I will be presenting an Intro to Unit Testing talk. I’ve given this talk many times over the years and I always love doing it. The talk’s in C# using NUnit and JustMock, but the concepts are the same regardless of whatever testing infrastructure you’re using. I hope to see you there! (Why not go register now...

    Testing Trends in 2013

    [Updated: Fixed grammar foul on ‘Tenants’ vs. ‘Tenets’.] 2012 is drawing to a close, and apparently all the worry about the Mayan calendar not extending past today is thankfully misplaced! The ending of a year is a good time for some introspection, and some thinking about what’s in store for the next year. Lots of smart folks in the testing field have their own opinions about what we’ll see (or won’t!) next year, but here are a few of my thoughts. Keep in mind this list is totally in line with my own very opinionated biases! Whole Team Testing This ...
