Trucov
Trucov is an open source code coverage analysis tool for GNU Compiler Collection, GCC versions 4.0 and later that aims to be a gcov replacement. Trucov improves upon gcov by providing more granular and machine readable output, such as DOT Language, DOT Files representing control-flow graph of the program. The use of DOT Language, DOT Files allows for other common tools like GraphViz to be used to produce coverage graphs. Trucov was developed as a senior design project{{Cite web, url=http://eecscapstone2009.blogspot.com/2009/09/cpts-team-trucov.html, title=WSU EECS Senior Design Projects: Fall 2009: CPTS Team Trucov: Progress report poster 10-5-09, date=18 September 2009 at Washington State University. Features * Produces coverage analysis on a per source, per function, and per branch level * Provides both textual and graphical coverage reports that are easier to use and understand * Automatically finds all the source files inside of a project * Detects how many times a particular b ...

Code Coverage
In software engineering, code coverage, also called test coverage, is a percentage measure of the degree to which the source code of a program is executed when a particular test suite is run. A program with high code coverage has more of its source code executed during testing, which suggests it has a lower chance of containing undetected software bugs compared to a program with low code coverage. Many different metrics can be used to calculate test coverage. Some of the most basic are the percentage of program subroutines and the percentage of program statements called during execution of the test suite. Code coverage was among the first methods invented for systematic software testing. The first published reference was by Miller and Maloney in '' Communications of the ACM'', in 1963. Coverage criteria To measure what percentage of code has been executed by a test suite, one or more ''coverage criteria'' are used. These are usually defined as rules or requirements, whi ...

Gcov
Gcov is a Code coverage, source code coverage analysis and statement-by-statement Profiling (computer programming), profiling tool. Gcov generates exact counts of the number of times each statement in a program is executed and annotates source code to add instrumentation. Gcov comes as a standard utility with the GNU Compiler Collection (GCC) suite. The gcov utility gives information on how often a computer program, program executes segments of code. It produces a copy of the source file, annotated with execution frequencies. The gcov utility does not produce any time-based data and works only on code compiled with the GCC suite. The manual claims it is not compatible with any other profiling or test coverage mechanism, but it works with LLVM, llvm-generated files too. Description gcov produces a test coverage analysis of a specially instrumented object code, program. The options -fprofile-arcs -ftest-coverage should be used to compile the program for coverage analysis (first optio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Source
Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use and view the source code, design documents, or content of the product. The open source model is a decentralized software development model that encourages open collaboration. A main principle of Open-source software, open source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open source appropriate technology, and open source drug discovery. Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase ''open source'' became widely adopted, developers and producers used a variety of other terms, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Compiler Collection
The GNU Compiler Collection (GCC) is a collection of compilers from the GNU Project that support various programming languages, Computer architecture, hardware architectures, and operating systems. The Free Software Foundation (FSF) distributes GCC as free software under the GNU General Public License (GNU GPL). GCC is a key component of the GNU toolchain which is used for most projects related to GNU and the Linux kernel. With roughly 15 million lines of code in 2019, GCC is one of the largest free programs in existence. It has played an important role in the growth of free software, as both a tool and an example. When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C (programming language), C programming language. It was extended to compile C++ in December of that year. Compiler#Front end, Front ends were later developed for Objective-C, Objective-C++, Fortran, Ada (programming language), Ada, Go (programming la ...

DOT Language
DOT is a Graph (discrete mathematics), graph description language, developed as a part of the Graphviz project. DOT graphs are typically stored as Computer file, files with the .gv or .dot filename extension — .gv is preferred, to avoid confusion with the .dot extension used by versions of Microsoft Word before 2007. dot is also the name of the main program to process DOT files in the Graphviz package. Various programs can process DOT files. Some, such as ''dot'', ''neato'', ''twopi'', ''circo'', ''fdp'', and ''sfdp'', can read a DOT file and render it in graphical form. Others, such as ''gvpr'', ''gc'', ''acyclic'', ''ccomps'', ''sccmap'', and ''tred'', read DOT files and perform calculations on the represented graph. Finally, others, such as ''lefty'', ''dotty'', and ''grappa'', provide an interactive interface. The GVedit tool combines a text editor and a non-interactive viewer. Most programs are part of the Graphviz package or use it internally. DOT is historically an acron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
