Many systems and monoliths that have been built a long time ago were also modular, but their modules were mostly based on the classical Three-tier Architecture. Such a setup has a low testability, because the Business layer required the Data Access Layer (DAL) to operate even in unit tests (or you had to do a code surgery to find seams, if there were ones).
