Lizard is an extensible Cyclomatic Complexity Analyzer for many programming languages including C/C++ (doesn't require all the header files or Java imports). It measures the number of linearly independent paths through a function's source code. Share. data complexity, module complexity, algorithmic complexity, call-to, call-by, etc.). The cyclomatic complexity number is basically the number of decisions in the source code. This metrics give also an indication about testing: each function should have at least as many test cases as indicated by its cyclomatic number. All functions should have a cyclomatic complexity of 10 or less. LimeReport LimeReport - multi-platform C++ | Qt report generator library written using Qt framework and intende of nodes of the graph; P => The no of connected components; There is an alternate formula if we consider the exit point which backs to your entry point.

Die McCabe-Metrik (auch zyklomatische Komplexität – cyclomatic complexity) ist eine Softwaremetrik, mit der die Komplexität eines Software-Moduls (Funktion, Prozedur oder allgemein ein Stück Sourcecode) gemessen werden kann. Use Git or checkout with SVN using the web URL. The Cyclomatic complexity uses a simple algorithm to calculate the program complexity. Why do small merchants charge an extra 30 cents for small amounts paid by credit card? The JaCoCo Jenkins plugin inspects the results of the various JUnit tests run during the build job's test phase and generates a code coverage report. It is a quantitative measure of the number of linearly independent paths through a program's source code. It has some very cool/useful features … The tool is ran from a command line in Linux or MacOS (or could possibly be ran on Windows from Cygwin but I have not attempted this). +2 votes . A tool for measuring cyclomatic complexity of C code. Where was this picture of a seaside road taken? If nothing happens, download Xcode and try again. Fan-out is a measurement of the number of different functions that are called by a given function, plus the number of data structures that it updates. Cyclomatic complexity of a code section is the quantitative measure of the number of linearly independent paths in it. Cyclomatic complexity is still a useful test coverage tool. Nodes represent parts of the source code having no branches and arcs represent possible control flow transfers during program execution. Halstead metrics are based on the number of operators and operands in the source code: … It also does copy-paste detection (code clone detection/code duplicate detection) and many other forms of static code analysis. It was developed by Thomas J. McCabe, Sr. in 1976. Once this is produced, it is simply: M = E – N + 2 E is the number of edges of the graph, N is the number of nodes and Mis McCabe’s complexity.
