You can make modifications to the cql-cli source code and compile it locally with:
go build .
You can then run the cql-cli executable directly or add a link in your $GOPATH to run it from a project:
ln -sf cql-cli $GOPATH/bin/cql-cli
We use the standard test suite in combination with github.com/stretchr/testify to do our unit testing.
To run them, please run:
make test
