• Advanced mocking: anonymous test spy

  When practicing TDD, I create interfaces to abstract away the ugly stuff, like databases, file I/O, web service calls, email messages, and other external systems. I can run tests now that don't have to interact with real implementations of these external... Posted Mar 06 2008, 10:43 PM by bogardj with | with 24 comment(s) Filed under: Testing, TDD

• Advanced mocking: auto-interaction testing

  When dealing with legacy systems or those not designed with specific testability scenarios in mind, you have to test your changes in non-traditional means. In normal mocking (or test double ) scenarios, you have some kind of external dependency that you...

• Unit testing MonoRail controllers - Redirects

  When developing with MonoRail , one of the common operations is to redirect to other controllers and actions. Originally, I looked at the BaseControllerTester to help test, but it required a little too much knowledge of the inner workings of MonoRail...

• WatiN and INamingContainer adventures

  I decided to add a simple WatiN acceptance test today to validate our login page. When a user enters invalid credentials, the page should show an error message. To test this, I need to set the text of the username and password, and click the Login button... Posted Jan 23 2008, 03:16 PM by bogardj with | with 2 comment(s) Filed under: ASP.NET, Testing

• Stop the madness

  I've been extending a legacy codebase lately to make it a bit more testable, and a few small, bad decisions have slowed my progress immensely. One decision isn't bad in and of itself, but a small bad decision multiplied a hundred times leads to...

• Progress made

  I just wanted to highlight a quote from Scott Guthrie's recent post on MVC (emphasis mine): VS 2008 Professional now includes built-in testing project support for MSTest (previously in VS 2005 this required a Visual Studio Team System SKU), and our...

• A downcasting tragedy

  And now, for another tale of legacy code woe, here's a gut-wrenching tragedy of OCP and downcasting , in five acts . Exposition We have a feature we're implementing that when the store's configuration settings allow for a survey link to be...

• Coding without confidence

  As a favor to my wife, I developed an Excel application to help her employer out with scheduling and status in a small wood manufacturing shop. Excel was chosen as it was the lowest barrier to entry, and the quickest to get out the door. It wasn't... Posted Nov 12 2007, 03:38 PM by bogardj with | with 2 comment(s) Filed under: Testing

• Record and playback state in ASP.NET

  Most ASP.NET applications hold various state objects in Session, Application, or other stateful mediums. For regression testing and defect reproducing purposes, often I want to capture the exact state of these objects and replay them back at a later time...

• Legacy code testing techniques: subclass and override non-virtual members

  This post was originally published here . One of the core techniques in Michael Feathers' Working Effectively With Legacy Code is the "Subclass and Override Method" technique. Basically, in the context of a test, we can subclass a dependency... Posted Aug 31 2007, 03:22 PM by bogardj with | with no comments Filed under: Legacy Code, C#, Testing

• Introducing Behave#

  This post was originally published here . I really like the idea of executable requirements. Executable requirements is the idea that I can express requirements from the business in a human-readable, executable format. Part of fulfilling the requirement...

• Unit testing with stubs and Rhino Mocks

  This post was originally published here . I've been using Rhino Mocks for about a year now, and Oren has never failed to impress me with the features he keeps adding on a regular basis. I needed to test a particular method that accepted an IProfile... Posted May 23 2007, 11:25 AM by bogardj with | with no comments Filed under: Agile, Testing

• Classifying tests

  This post was originally published here . When defining a testing strategy, it's important to take a step back and look at what kinds of tests we would like to develop. Each type of test has a different scope and purpose, and can be developed by different... Posted Apr 23 2007, 08:57 AM by bogardj with | with no comments Filed under: Agile, Testing
