Go lang continuous test shell function

This function is assumed to be run from the root of a Go lang project. It calculates the sha1 value of the project's directory tree every 10 seconds. If the value of the command has changed then go test ./... is executed causing all the tests in the project to be run.

Shell function

function goct() {
    local project_hash=-1
    while true; do
        local new_project_hash="$(find . -type f -print0 | sort -z | xargs -0 shasum | shasum)"
        if [ "${new_project_hash}" != "${project_hash}" ]; then
            project_hash="${new_project_hash}"
            echo "Change detected - executing tests..."
            go test ./...
            echo
        fi
        sleep 10
    done
}
