Run tests by the lines they exercise
cargo-line-test
relies on cargo-llvm-cov
and requires it to be installed independently:
cargo install cargo-line-test cargo-llvm-cov
# Build cargo-line-test database
cargo line-test --build
# Run the tests that exercise src/main.rs:99
cargo line-test --line src/main.rs:99
# Run the tests that exercise lines changed by diff
git diff | cargo line-test --diff
# Update the database following source code changes
cargo line-test --refresh
