SemillaGen let's you create (Actionscript3.0 based) projects and classes with ease. SemillaGen generated projects or classes are customizable via templates. The default templates setup the project for Continuous Integration using FlexUnit. the default class template creates a class and a test case automatically. usage: To create a new project run: $ semillagen project MyAwesomeProject $ ls MyAwesomeProject To create a new class with test case: $ cd MyAwesomeProject $ semillagen class com.semilla.MillionDollarClass You will see that semillagen created the following files: src/com/semilla/MillionDollarClass.as test-src/com/semilla/MillionDollarClassTest.as The default template is ready for building as soon as created. To build and test your project we use rake. $ rake Rake will build a debug and release versions of your project. It will also create a FlexUnit test swf and run the test. You will see the results of the tests and also you will see some xml files under the [test-report] folder. These reports are JUnit compatible. You can use a CI tool like Jenkins to automatically build and test your project.
