Follow-up to Building a Test Script Environment with C# and IronRuby, pt 1, wherein we change emphasis from coding tests in Ruby to writing them in English (Gherkin) with the help of SpecFlow.
After that October post, I managed to construct a full system/regression test suite for a key data-management application, using the combination of Ruby and C# as described. My team has been able to go through several cycles of…
A co-worker overheard the comment that "agile [software development] is not always a good fit for introverts," or something along those lines, while listening to a webinar on agile testing. On the surface, it is hard to deny that claim. Right there in the Agile Manifesto we have two obvious yellow or even red flags:
Now jumping over to the Principles, we find two more orange flags:
Sometimes you need to go back to the basics - including basic technology. In this case, I mean sticky notes. Yes, they are a remarkable form of technology. I like doing everything the digital way. I abhor using paper when not necessary, because of the waste factor. Although I love the idea of note cards for user story development, I've been thankful that they are impractical for my development team. But, I think it is time to heed good advice.
We build a lot of console applications, and Windows services, that process inbound and outbound files in one way or another. Most depend on configuration data and some load (or unload) business data from a database, in addition to accessing the files. Testing these has always been a chore, to say the least: configurations change, data are deleted, and there's never enough time. After building a few rudimentary tools that have helped, necessity, and Agile Testing: A Practical Guide for Testers and Agile Teams, has convinced me that it is time to get serious about system/integration test automation, just as I did about unit test automation a few years ago. This is the first of a n-part series of posts on this process

careful use of jQuery. There are probably many different solutions already out there, but I wanted to learn how to write one for myself. Key functions: closest, detach, append, prev, next, before, and after.
Wherein I record a few tips on the use of System.ComponentModel.DataAnnotations, which I am likely to forget if I do not need to think about them again for some months…
Growing Object-Oriented Software, Guided by Tests by Steve Freeman and Nat Pryce
I did not realize how much I still have to learn about writing good object-oriented (OO) code, and about hewing to a tight test driven development (TDD) methodology, before I read Growing Object-Oriented Software, Guided By Tests. My education in OO and unit testing has been largely theoretical, with no time spent directly learning from experienced OO programmers; my best mentor was a COBOL coder. Books like Design Patterns: Elements of Reusable Object-Oriented Software ("Gang of Four"), Patterns of Enterprise Application Architecture, Applying UML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, Xunit Test Patterns: Refactoring Test Code, and others are wonderful but have few detailed real-world business-case examples.
Moles is a powerful and useful framework for unit testing. Or was. But even then, it was overused (at least by me). But no more!
The first clue that I might need to walk away from Moles was the recent difficulty another developer was having in trying to get a unit test project up-and-running on his computer. I had installed what was current in early 2011, and he had installed the current version from last 2011. Turns out there was a significant change – the config file no longer worked. We had to update the assemblies correctly on my machine, rebuild many times, and fool around with manually removing some assemblies. It got confusing and messy. I suppose that's why MS still labeled this version as < 1.0.
Here’s an interesting scenario: I have a Linq-to-Entities query that is giving me no results when performing a system test, but when I look in the database, logically there should be results. Better yet, the unit test passes. How can that be?
