Test can only depend on Model, Controller
depend-on(com.app.View, com.app.View) = False depend-on(com.app.View, com.app.Test) = False depend-on(com.app.View, com.app.Util) = True
View can only depend on Model, Controller
depend-on(com.app.Test, com.app.View) = False depend-on(com.app.Test, com.app.Test) = False depend-on(com.app.Test, com.app.Util) = False
Test, View can only depend on Model, Controller
