Branch Coverage
In plain terms
A metric of how many code branches tests exercise.
Going deeper
Branch coverage measures the percentage of decision branches (if/else paths) executed by tests, more thorough than line coverage. It checks both sides of conditionals.
Under the hood
Higher fidelity than statement coverage but still no guarantee of correctness; 100% is rarely worth chasing.
Examples
Coverage reports, test thoroughness, if/else paths, quality metrics.
Think of it like...
Like ensuring you've walked down every fork in a maze, not just most hallways.
