Emerging modularization techniques such as aspects and

their precursors such as events in implicit invocation

languages aim to provide a software engineer with better

facilities to separate conceptual concerns in software

systems. To facilitate adoption of these techniques in

real world software projects, seamless integration into

well-accepted practices such as a test-driven

development process is essential.

To that end, the main contribution of this thesis is an

analysis (both pragmatic and theoretical) of the impact

of a class of such techniques on the efficiency of a

test-driven development process, which involves frequently

compiling and testing programs in a process commonly

known as the edit-compile-test cycle.

I study two variants: the popular model of aspects as

in the AspectJ-like languages, and a recently suggested

alternative based on quantified, typed events embodied in

the Ptolemy language.

I present a case study analyzing two variants of the

aspect-based model on two open source projects and a

theoretical analysis of the quantified, typed

event-based model.

My results show that a seamless adoption of the

aspect-based model requires careful balancing of

competing parameters to ensure efficiency of a

test-driven development process, whereas a quantified,

typed event-based model naturally supports separate

compilation thus decreasing the time spent in the

edit-compile-test cycle.
