    1. TDD GUI Using MVP (and the pair programming game) Peter Provost peter.provost@microsoft.com http://www.peterprovost.org/

    2. What We’re Going to Do Pair Programming Test Driven Development Model-View-Presenter

    3. Pair Programming Yes, we really do this No, we’re not joking

    4. Test Driven Development (TDD) Create a failing test Make it pass Re-factor for clarity and to remove duplication

    5. Model-View-Presenter (MVP) MVC and MVP are similar and usually exchanged colloquially Both provide separation of view and control In MVC, a view is bound to a controller interface In MVP, the presenter is bound to a view interface

    6. The Story

    7. Requirements Windows Forms user control Rooted to a folder in the file system User can choose the folder for the root Shows all folders/files from the root down Does not show hidden folders/files Uses icons provided by our graphic designer For performance reasons, it shouldn’t load the whole tree at once User can specify a filter criteria for the files.

    8. Possible Tests Starts rooted on C:\ Settable root Verify root is valid User expanding a directory loads children Node text for root node is full path Node text for child node is relative name only Hidden files/folders not shown Folders and files have different icons
