Creating the right development environment for building maintainable mobile apps should be the primary concern of a team embarking on native app development. Constructing a comprehensive continuous build process integrating unit testing and build monitoring should be one of the development teams primary goals.

This session will show you how to leverage a number of mature and powerful tools to make creating your titanium development process quick and effective.
* Unit testing in Titanium
* Testing with TiMocha
* Testing inside Titanium Studio
* Taking advantage of Mocha JSON reporter
* Continuous integration with travis and titanium-cli

3. AGENDA Introduction to Building Maintainable Mobile Apps Unit testing in Titanium Testing with ti-mocha Taking advantage of ti-mocha reporter Demo What next?
4. WARNING BEFORE WE START Unit testing != TDD Limitations mobile app testing? (UI) Don't write tests against titanium api? ( e.g. should(win.open).be.a.Function; ) Myths: 1. Not everything can be tested with unit tests? 2. Projects take longer because of the additional test code that has to be written.
5. BUILDING MAINTAINABLE TITANIUM APPS
6. MAINTAINABLE?? TITANIUM?? APP?? Ensuring bugs are found fast and automatically via automated tests. Prevent breaking of already tested functionality when adding code or modifying it. Allows for easy refactoring without worrying of breaking changes. Make changes to support new environments operating systems or tools Make it easier for others to maintain the software
7. UNIT TESTING IN TITANIUM? Frequent changes in Titainium API/Android SDK/iOS SDK. Helpfull while adopting to new platform which ti going to support in future Jeff Haynie says: TiO2 (Titanium + Oxygen) is the most important oxide, which exists in three important polymorphs; anatase, brookite, and rutile. Oxygen is vital to life on earth -- and so is testing to building great software.
8. TRICKS TO TEST TITANIUM APPS Avoid global events and using the titanium namespace for storing things unless necessary Use commonjs modules for everything In the event callbacks, use functions that you can call anytime you want, that way it is a lot easier to share common behaviours and call them anywhere you want Reuse code
