TypeMock Case Study in Corillian

We have completed a case study of implementing TypeMock in Corillian. Corillian is the company that creates Online Banking Software, and you can imagine how important security and quality is.

Corillian is the company that Scott Hanselman is the Chief Architect. Scott has promised me that he will write an article about TypeMock as well.

We found that the biggest value of using TypeMock is that it eased the adoption of unit testing to all the developers. One of the main obstacles in creating Agile Development Teams. The team members where really happy to adopt testing early, and had both the freedom to develop in their own style without compromising the testability of their code.

The value of having agile teams is well know and IBM pitches the efficiency of agile programming. But we have managed to find some interesting metrics:

  • The number of tests in one team grew from 100 to 600 within 1.5 months! That’s a 500% increase.
  • The test coverage (amount of code covered by the tests) grew by 50% within 2 months
  • The actual tests are 25% faster to code! that saves time to create more features.

You can grab the Case Study pdf file off the TypeMock site

  1. I wasn’t able to easily view the case study PDF using Firefox (on the Mac or PC). I think you may need to tweak your server MIME types. You can save as file – otherwise it comes up as scrambled text.
