To run all of the tests for the repo run:

cargo make test

For local code coverage reports run:

# Install the tools first if you haven't done so. The llvm tools must be available
# on the path for this to work correctly.
cargo make install-tools

# Then coverage can be run like so:
cargo make coverage
