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(isSeven(4), false) 
Test.assertEquals(isSeven(9), false)
Test.assertEquals(isSeven(7),  true)
Test.assertEquals(isSeven(10),  false)
Test.assertEquals(isSeven(20),  false)
Test.assertEquals(isSeven(7),  true)
