Multiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. [1]
For example, assignment of the number of days in a month (excluding leap years) could be achieved by using either a switch statement or by using a table with an enumeration value as an index. The number of tests required based on the source code could be considerably different depending upon the coverage required, although semantically we would ...
State-based CRDTs (also called convergent replicated data types, or CvRDTs) are defined by two types, a type for local states and a type for actions on the state, together with three functions: A function to produce an initial state, a merge function of states, and a function to apply an action to update a state.
Legacy code may not have been designed under a defensive programming initiative, and might therefore be of much lower quality than newly designed source code. Legacy code may have been written and tested under conditions which no longer apply. The old quality assurance tests may have no validity any more. Example 1: legacy code may have been ...
Google Test, often referred to as gtest, is a specialized library utilized to conduct unit testing in the C++ programming language. This library operates under the terms of the BSD 3-clause license. [2] Google Test is based on the xUnit architecture, a systematic methodology for assessing software components. [3]
Conflict-driven clause learning works as follows. Select a variable and assign True or False. This is called decision state. Remember the assignment. Apply Boolean constraint propagation (unit propagation). Build the implication graph. If there is any conflict Find the cut in the implication graph that led to the conflict
Polyspace is a static code analysis tool for large-scale analysis by abstract interpretation to detect, or prove the absence of, certain run-time errors in source code for the C, C++, and Ada programming languages. The tool also checks source code for adherence to appropriate code standards. [3]
Formally, the reference context-free grammar of the language is ambiguous, meaning there is more than one correct parse tree. In many programming languages, one may write conditionally executed code in two forms: the if-then form, or the if-then-else form. (The else clause is optional.):
