Things used in this project


not a schematic...
Just to pass the validation.
The contest asked for a VUI diagram..I searched on internet and there is no mention about it..Also I have asked on twitter ( @dega1999 ) no responses :)

An xml to logically connect: XML
A file structure I built for my needs.
I feel it is complicated How to connect the piecese of an alexa skill.
This is a logical connection between the intent, utterances and team.
There is a python script that is able to parse this xml and produce a list of utterances.
<!-- Variables are with 2 #, like #field#. It will be replaced by <field> from the tool
     it will also extract ALL the utterance in a SampleUtterance.txt file

the user will be able to ask: match results, the next match of a team, the last result of a team

A test classJavaScript
This class is used to test the "core" of the application.
It was extremely useful for minimize the error once the skill was submitted.
I also used to print all the teams to insert in a special custom slot.
var EuroUtils = require('./EuroUtils');

var euroUtils = new EuroUtils();
console.log("TEST 1: count teams");

var teams = euroUtils.teamsForCup();
if ( teams.length !== 24 ) {
	console.log("The number of teams is not 24!");

console.log("Listing teams...");
for(var i=0;i<teams.length;i++) {
	console.log("" + teams[i]);

console.log("TEST 2: group for team Sweden");
var tempTeam = "Sweden";
var groupForTeam = euroUtils.groupForTeam(tempTeam);
if (groupForTeam !== 'E')
	console.log(""+tempTeam+ " found in wrong group: " + groupForTeam);

console.log("TEST 3: group for unexisting team");
tempTeam = "ABCDE";
var groupForTeam = euroUtils.groupForTeam(tempTeam);
if (groupForTeam !== false)
	console.log("Unexisting team ("+tempTeam+ ") found in a group... " + groupForTeam);

console.log("TEST 4: teams for group B");
var tempGroup = 'B';
var teamsForGroup = euroUtils.teamsForGroup(tempGroup);
var groupB = ["England","Russia","Wales","Slovakia"];

for(var i=0; i < groupB.length ; i++) {
	if(teamsForGroup.indexOf(groupB[i]) === -1) {
		console.log("Team " + groupB[i] + " not found on group B");
		for(var j=0;j<teamsForGroup.length;j++)

console.log("TEST 5: teams for unexisting group");

tempGroup = "ABCDE";
teamsForGroup = euroUtils.teamsForGroup(tempGroup);
if( teamsForGroup !== false) {
	console.log("Teams ("+teamsForGroup.length+") found for unexisting group");

console.log("TEST 6: adversary for team Sweden");
tempTeam = "Sweden";
adversaries = euroUtils.adversariesForTeam(tempTeam);
if( adversaries === false ) {
	console.log("Adversary for " + tempTeam + " not found..");
if(adversaries.length !== 3 ) {
	console.log("Adversary for " + tempTeam + " not 3!");
	for(var i=0;i<adversaries.length;i++)

if( adversaries.indexOf("Belgium") === -1 && 
	adversaries.indexOf("Italy") === -1 && 
	adversaries.indexOf("Republic of Ireland") === -1 ) {
	console.log("One of the adversary of Sweden is missing!");

console.log("TEST 7: adversary for unexisting team");
tempTeam = "ABCDE";
adversaries = euroUtils.adversariesForTeam(tempTeam);
if( adversaries !== false ) {
	console.log("Found adversaries for unexisting team!");

console.log("TEST 8: all groups letter");
var letters = euroUtils.allGroups();

if( letters.length !== 6 ) {
	console.log("Missing some letters..");
	for(var i=0;i<letters.length;i++) 

console.log("TEST 9: Formatted Output");
var lettersFormatted = euroUtils.formattedOutput(euroUtils.allGroups());
if ( "A,B,C,D,E,F," !== lettersFormatted ) {
	console.log("Wrong Output: [" + lettersFormatted + "]");

console.log("TEST 10: Formatted Output empty array");
if ( euroUtils.formattedOutput([]) !== "I don't know, sorry." ) {
	console.log("Error on empty input array");

console.log("ALL TESTS PASSED");
