Everything you need to know to shift left
This resource is more like an online book than an article, taking you step-by-step in the journey to implementing continuous testing. It covers the management of source code, environments and infrastructure, incident and testing; along with all the possible types of necessary testings. The more checks are implemented along the way, the fewer risks. At the end there is a handy way to quantify your testing maturity level, which can assist in selling the project internally.
