@cvennevik Integration is a misunderstood term for sure. It starts with the second line of code that must integrate with the first. Ends when? I view acceptance testing as testing integration between system(s) and business processes. So it's all pervasive. Martins description is developer focused I think.

I'm working my way through testing terms trying to provide explanations rather than definitions. https://www.youtube.com/watch?v=oFayGwn9AV8&list=PLd0u8I-wgEwPDjVkYbmzad-hOnxq_GnY4

Perhaps I should tackle Integration Testing next?
