This document discusses software testing techniques and strategies. It introduces testing pyramids that prioritize unit testing and outlines different levels of testing including automated testing of code, services, UI, and full integration. Specific CFML and JavaScript testing approaches are covered. Test-driven development (TDD) principles and the benefits of writing tests first are explained. The document provides links to additional CF Objective conference sessions on related testing topics.

Testing Strategies and Techniques
- 1. TESTING TESTING EVERYWHERE KEV MCCABE 14TH MAY 2014 CF OBJECTIVE 2014 http://nud.gr/QIZntJ
- 4. TESTING PYRAMID Exploratory Acceptance* Integration* Unit Tests* * Automated Testshttp://nud.gr/QIZntJ
- 5. INVERTED TESTING PYRAMID E x p l o r a t o r y Acceptance* Integration* Unit Tests** Automated Tests http://nud.gr/QIZntJ
- 6. AUTOMATED TESTS Comment from my Unit Testing Session @ CF Summit: This one I liked the least. Seems like overkill to write 10 times more code just to test one tiny piece of the application. I can understand how it would be helpful for large teams where the work is split among multiple developers, but for a small team and a rapid dev cycle, this just seems like unnecessary overhead. I wasn't convinced of the real-world applicability. If this was you I hope I can convince you http://nud.gr/QIZntJ
- 8. AUTOMATION CFML Code • Beans • Services • Handlers JavaScript • Plain Javascript • jQuery • AngularJS etc Database UI http://nud.gr/QIZntJ
- 9. DATABASE TESTING To be honest – not found a good one So test using TestBox This is actually good! You need a DB Instance just for this. So you can tear it down and refresh as needed http://nud.gr/QIZntJ
- 10. CFML Testing of Beans • Make sure they hold the data you intended • Have any special functions? Services • SRP • Right calls Handlers • If using a MVC framework make sure it’s doing what you wanted http://nud.gr/QIZntJ
- 11. JAVASCRIPT Yes you can test your JavaScript Test Plain JavaScript jQuery calls AngularJS applications http://nud.gr/QIZntJ
- 12. FULL INTEGRATION TESTS Testing in different browsers Create a Framework Make it interesting for the business • They will really care about this level! • Once you show them it working http://nud.gr/QIZntJ
- 14. TDD Why do we do TDD? We do TDD for one overriding reason and several less important reasons. The less important reasons are: • We spend less time debugging. • The tests act as accurate, precise, and unambiguous documentation at the lowest level of the system. • Writing tests first requires decoupling that other testing strategies do not; and we believe that such decoupling is beneficial. Those are ancillary benefits of TDD; and they are debatable. There is, however, one benefit that, given certain conditions are met, cannot be debated: Robert “Uncle Bob” Martin http://blog.8thlight.com/uncle-bob/2014/04/25/MonogamousTDD.html http://nud.gr/QIZntJ
- 15. TDD If you have a test suite that you trust so much that you are willing to deploy the system based solely on those tests passing; and if that test suite can be executed in seconds, or minutes, then you can quickly and easily clean the code without fear.
