The command "gcov --branch-probabilities ${filename-cpp}" is used to generate code coverage information using the gcov tool.
Gcov is a coverage profiling tool for GNU based compilers that enables developers to analyze which parts of their code have been tested by their test suite.
Here's a breakdown of the command:
- "gcov" is the name of the tool that is being executed.
- "--branch-probabilities" is an option for gcov that tells the tool to provide branch coverage information. Branch coverage measures the percentage of decision points in the code that have been executed.
- "${filename-cpp}" represents a placeholder for the name of the C++ source file that you want to generate coverage information for. You need to replace this placeholder with the actual filename of your C++ source file.
When you run this command, gcov will analyze the specified C++ source file and generate a coverage report that includes branch probabilities. This report will show which branches in your code were taken during testing and provide information about the likelihood of each branch being executed.
