To achieve testability in modular software we need to leverage the Dependency Inversion Principle (DIP) up to the level of application architecture. That was the reasoning behind introducing the concept of Infrastructure-Modules. When we extract all the infrastructure code from Business-Modules, they can stay focused on the business logic and have no design/compile-time dependencies on any untestable infrastructure code. As a side effect, we achieve Separation of Concerns.
