Well-known agilist and TDD expert J.B. Rainsberger has begun a series of posts to explain why his experience has led him to the thought-provoking conclusion that "integration tests are a scam".
Elisabeth Hendrickson, A.K.A "testObsessed", presents a thought-provoking stance on triaging bugs in an agile project. She discusses her feelings that problems found during the iteration are not "bugs", that only the Product Owner has the right to call something "bug", and that a healthy agile team might likely have no need for a bug tracking system.
In this interview filmed during RubyFringe 2008, Luke Francl explains his position towards testing. While supporting unit testing, he thinks testing is not going to reveal all application defects. Development teams should practice code reviews and usability tests which are likely to discover bugs not visible though other methods.
In this talk from RubyFringe, Luke Francl asks: is developer-driven testing really the best way to find software defects? Or is the emphasis on testing and test coverage barking up the wrong tree?
Kent Beck, renowned co-father of XP, TDD, and JUnit itself, tells a story about tracking down a defect in a new JUnit feature, JUnitMax, with unit tests instead of a debugger. He explains a method shown to him by current JUnit lead developer, David Saff, where a high level unit test is recursively inlined until a super concise test is created down at the very root of the defect.
In this presentation held during Agile 2008, Alan Shalloway, CEO and founder of Net Objectives, presents the Lean software development principles and practices and how they can benefit to Agile practitioners.
Christian Gruber takes some time to clarify the TDD stance on using code coverage metrics. He discusses what code coverage metrics do and don't tell you, how TDD fits into the picture, and how one might be best advised to use their code coverage metrics.
Scott Schimanski recently added his voice to those talking about the power of a clear definition of "done." Scott points out there is both business and personal value in a well-defined meaning of "done". The business can count on shipping features that are done, without making any additional investment, while individuals really seem to enjoy the sense of accomplishment that comes with "done."
What is a good test? How do we know if we're writing good tests? Kent Beck, Roy Osherove, Mike Hill and others provide some insight.
In “Just Ship Baby” Kent Beck, author of the JUnit Framework, reminds us that the point of all the Agile processes and practices is to produce shipping software. If they’re getting in the way of shipping software – then perhaps you need to break the rules.
A Technical Debt Workshop was recently held to improve our industry's understanding of and approach to "technical debt", resulting in some interesting ideas. Among them, changing our perception of the problem to focus on "assets" rather than "debt", an idea now receiving quite a bit of attention by people such as Michael Feathers and Brian Marick.
Gojko's Fixture Gallery is a cookbook for FIT/Fitnesse fixtures and version 2.0 has been released with Java, C# and Python code samples.
Greg Wilson challenged the aa-ftt community to support efforts to improve college graduates ability to deliver "product-quality code". Wilson's request primarily involves providing simplified versions of the tools used by professionals, such that they're digestible by undergraduate students.
Enerjy studied tens of thousands of source code files and found the optimum Cyclomatic Complexity number is 11, with a 28% defect probability. In fact, you are more likely to encounter a defect if you have lower complexity - is it time to make your methods are more complicated?
Fixture Gallery is a new open doc cookbook by Gojko Adzic for FIT/FitNesse tests. It provides developers with a quick overview of the most important fixture types and concepts for agile acceptance testing using the FIT framework.
