This week I heard some chatter in certain iOS groups that I belong to about whether testing your iOS, macOS, watchOS, or tvOS applications provided any immediate value in the development life cycle.  As opposed to developing features without testing and getting them to market right away and then iterating upon them in a highly agile methodology.  Coming from a background where I like to write a lot of automated tests and system tests for software that I write, I have to admit, this point of view really made me pause for a moment to try and see the perspective from both sides.

One of the major parts of any software development cycle is testing.  Whether that testing is performed on just one feature or an entire product I think that any developer can agree that code and product functionality needs to be tested before it is deployed.  As a developer, one thing that I continuously find myself wondering is when is it an appropriate time to test my code?  I wonder if it cost effective and productive to perform testing on a feature by feature basis?  I wonder if I should wait until an entire section of features is completed to test functionality?
