UCTSystem is a prototype tool designed to perform automatic test generation from UML requirements. It uses UML use cases enhenced with contracts (i.e. precondition and postconditions) to build an execution model allowing all valid sequences of use cases. Using this execution model and several test criteria, it generates test objectives as sequence of use cases to exerce. It includes both criteria for functional testing and a criterion for robusness testing. Those test objectives are then mapped into test cases using test templates.
Test driven development (TDD) is emerging as one of the most successful developer productivity enhancing techniques to be recently discovered. The three-step: write test, write code, refactor – is a dance many of us are enjoying. This site is dedicated to promoting techniques, tools, and general good will in the test-driven community.
Jumble is a class level mutation testing tool that works in conjunction with JUnit. The purpose of mutation testing is to provide a measure of the effectiveness of test cases. A single mutation is performed on the code to be tested, the corresponding test cases are then executed. If the modified code fails the tests, then this increases confidence in the tests. Conversely, if the modified code passes the tests this indicates a testing deficiency.
Die Seite wurde erstellt am 25. März 2005, also lange vor dem "offiziellen" Start von Google Print. So war am 27. März 2004 das vermisste Feature "Search inside the book" auch bei Google Print wieder erreichbar. Zunächst wurden Nachträge als NACHTRAG gekennzeichnet, nach einiger Zeit wurde dies aber zugunsten einer weblogartigen Fortführung der Seite aufgegeben. Die neuesten Einträge finden sich am Fuß der Seite. Ergänzend ist die Berichterstattung in http://log.netbib.deext. link heranzuziehen.

A. Newell, и H. Simon. Communications of the ACM, 19 (3):
113-126(марта 1976)p. 116:
"The Physical Symbol System Hypothesis. A physical
symbol system has the necessary and sufficient
means for general intelligent action."
p. 120:
"Heuristic Search Hypothesis. The solutions to
problems are represented as symbol structures.
A physical symbol system exercises its intelligence
in problem solving by search--that is, by
generating and progressively modifying symbol
structures until it produces a solution structure."
p. 121:
"To state a problem is to designate (1) a test
for a class of symbol structures (solutions of the
problem), and (2) a generator of symbol structures
(potential solutions). To solve a problem is
to generate a structure, using (2), that satisfies
the test of (1).".
