Behavioral software contracts allow programmers to strengthen the obligations and
promises that they express with conventional types. They lack expressive power, though …

Until now there has been no support for specifying and enforcing contracts within a lazy
functional program. That is a shame, because contracts consist of pre-and post-conditions …

Contract systems, especially of the higher-order flavor, go hand in hand with blame. The
pragmatic purpose of blame is to narrow down the code that a programmer needs to …

Contract monitoring for strict higher-order functional languages has an intuitive meaning, an
established theoretical basis, and a standard implementation. For lazy functional languages …

We present a new approach to contract semantics which expresses myriad monitoring
strategies using a small core of foundational communication primitives. This approach …

This dissertation demonstrates that a new empirical method, called the Rational
Programmer, can examine the pragmatics of contracts and gradual typing in the context of …

This dissertation introduces executable refinement types, a type system with the expressivity
of program contracts, and establishes their metatheory and accompanying implementation …

Runtime verification, as a field, provides tools to describe how programs should behave
during execution, allowing programmers to inspect and enforce properties about their code …

Assertions or contracts are an important technique to improve the quality of software. Thus,
assertions are also desirable for functional logic programming. Unfortunately, there is no …

Manifest contracts combine the rich specifications and runtime checking of higher-order
contracts [11] with a static type discipline. Conventional type systems prevent simple errors …
