Open Source Summit Europe 2023

Shift left and shift right have emerged as important paradigms for testing and building secure applications. Covering the complete SDLC also aligns with the shift everywhere paradigm. The choice of open source components can have far reaching consequences for software. Also here, testing is essential, but the tests will focus on the suitability of the component, both in its own right, but also in the context of the software. We call this Start Left  -  testing that can partially be conducted before the component is even in your code. Choosing the wrong component might result in starting all over again, adapting code to a new component. The shift paradigms over the past decade have highlighted the need for automatic testing. In this talk we discuss the shifting paradigms and focus on how such start left tests can be done. If successful, we can choose the right component from the start. We don't start over. We just start left.
