No, I actually meant "declarative" .... See this reference:
Quote:
In computer science, declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow. Many languages applying this style attempt to minimize or eliminate side effects by describing what the program should accomplish, rather than describing how to go about accomplishing it. This is in contrast with imperative programming, which requires an explicitly provided algorithm.

Declarative programming often considers programs as theories of a formal logic, and computations as deductions in that logic space. Declarative programming has become of particular interest recently, as it may greatly simplify writing parallel programs.

Common declarative languages include those of regular expressions, logic programming, and functional programming.

I see now that Ruby is not classified as a "declarative programming language", List of programming languages by category.

NAME
ATF -- introduction to the Automated Testing Framework DESCRIPTION
The Automated Testing Framework (ATF) is a collection of libraries to implement test programs in a variety of languages. These libraries all offer similar functionality and any test program written with them exposes a consistent user interface. Test programs using the ATF libraries rely on a separate runtime engine to execute them in a deterministic fashion. The runtime engine iso- lates the test programs from the rest of the system and ensures some common side-effects are cleaned up. The runtime engine is also respon- sible for gathering the results of all tests and composing reports. The current runtime of choice is Kyua, described in kyua(1). If your operating systems distributes ATF, it should also provide an introductory tests(7) manual page. You are encouraged to read it now. The rest of this manual page serves as a cross-reference to all the other documentation shipped with ATF. Language bindings atf-c(3) C programming interface. atf-c++(3) C++ programming interface. atf-sh(3) sh(1) programming interface. Miscellaneous pages atf-test-case(4) Generic description of test cases, independent of the language they are implemented in. atf-test-program(1) Common interface provided by the test programs written using the ATF libraries. SEE ALSO
kyua(1), tests(7) HISTORY
ATF started as a Google Summer of Code 2007 project mentored by The NetBSD Foundation. Its original goal was to provide a testing framework for the NetBSD operating system, but it grew as an independent project because the framework itself did not need to be tied to a specific operating system. Originally, ATF shipped the collection of libraries described in this manual page as well as a runtime engine. The runtime engine has since been replaced by Kyua and the old tools were removed in 0.20, which shipped in early 2014. As of late 2014, both FreeBSD and NetBSD ship ATF in their base systems and provide extensive test suites based on it.
