Continious testing of Go code

tips & tricks
1

This is surely a missing piece of my current Go IDE (LIteIDE), but I found and adapted this little shell function to test an entire Go tree whenever I make a change:

function goct() {
    local project_hash=-1
    local sleeptime=10
    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 ./...
            if [ $? -ne 0 ]; then
                echo "FAILED"
                # May take some fime to fix, so back off.
                sleeptime=120
                osascript -e 'display notification "Go Test Failed" with title "Go Failure" sound name "Submarine"'
            else
                sleeptime=10
            fi

            echo
        fi
        sleep $sleeptime
    done
}

Note: The notification thingy is OS X – so for Linux change or remove that.
