In January, we posted an article talking about Shift-Left Testing and its role in the software development lifecycle.
As a quick recap, shift-left testing entails moving the testing phase from right to left in the software lifecycle. Testing is performed earlier in the cycle, and testing takes place continuously, not just at the end of the cycle. This offers an alternative approach to testing that keeps up with continuous deployment.
Chronologically in the SDLC, the earliest forms of shift-left testing typically revolve around automation (i.e. running unit tests). This is because the smallest units come first, and customer-facing features have not yet been implemented or fully built out (thus making it difficult to test for functionality). Of course, you can still test early and often using automation, but is there a place for manual testing at the far left?
If so, when? And how would you implement it?
