Traditional test methodology holds that testing is a separate process out of step with the developer. Developer absence from quality assurance encourages a lack of customer empathy from the development team. Furthermore, the lack of developer involvement in quality allows issues to fester in the code base longer making them more expensive to fix. This methodology is also expensive in organizational employee cost as it encourages hiring a separate QA team to take responsibility.
Continuous delivery promotes developer awareness and empathy with the end user experience. Developers are tasked with delivering test coverage for the features they produce and overseeing them from development to production environments. This gives developers an opportunity to own and prove the quality of a feature.
