What is testing in production and why should it be performed?

Based on the experience from a project without TiP, reasons are given why the DTAP model is not suitable for testing modern public online services in the cloud. Apart from TiP being necessary, this paper also argues that TiP should be a regular test level. By comparing a test and the production environment, a view is given on how testing in production should be perceived as normal. Additional to this, a definition of TiP is given and the paper ends with questions for future research.

My thesis about testing in production is published in ENG – testing_experience_no_20_van_t_veer magazine.
