Trucov
Trucov is an open source code coverage analysis tool for GCC versions 4.0 and later[1] that aims to be a gcov replacement. Trucov improves upon gcov by providing more granular and machine readable output, such as DOT Files representing control-flow graph of the program. The use of DOT Files allows for other common tools like GraphViz to be used to produce coverage graphs. Trucov was developed as a senior design project[2] at Washington State University.
Features
[edit]- 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 block or branch of code has been executed
- Generates the control-flow graph of each function per source file
- Optionally hides coverage information of external libraries to better focus on the product under test
- Allows user to narrow the scope of coverage information by specifying specific functions or files
