TestCases

let Test = (function(){
    return {
        assertEquals:function(actual,expected){
            if(actual !== expected){
                let errorMsg = `actual is ${actual},${expected} is expected`;
                throw new Error(errorMsg);
            }
        }
    }
})();

Test.assertEquals(footballPoints(1, 2, 3), 5)
Test.assertEquals(footballPoints(5, 5, 5), 20)
Test.assertEquals(footballPoints(1, 0, 0), 3)
