javascript - JS unit test with Jasmine -

i new jasmine, infact started today , don't have prior knowledge writing js unit test cases. trying write simple test case in jasmine in order test basic js code. have added necessary scripts , libraries in project.

so here piece of js code. fetching local australian date , time , arranging them in particular format.

var date = {      formatfulldate: function(date) {         var localdate = this.getlocaltimefromaustraliatime(date),             month = this.addzerotofront(localdate.getmonth() + 1),             hour = this.addzerotofront(localdate.gethours()),             minute = this.addzerotofront(localdate.getminutes());          return localdate.getdate() + '/' + month + '/' + localdate.getfullyear() + ' ' + hour + ':' + minute;     },      formattime: function(date) {     var localdate = this.getlocaltimefromaustraliatime(date),         hour = this.addzerotofront(localdate.gethours()),         minute = this.addzerotofront(localdate.getminutes());      return hour + ':' + minute;     },      addzerotofront: function(whatever) {     if (whatever < 10) whatever = "0" + whatever;     return whatever;     },      getutctimeoffset: function() {     var date = new date();     return date.gettimezoneoffset();     },      getlocaltimefromaustraliatime: function (date) {     var utctime = new date(date.gettime() - 11*60*60*1000),         localdate = new date(utctime - this.getutctimeoffset()*60*1000);     return localdate;     } } 

in above mentioned code can test various things example function fetching correct timezone, adding 0 prior time, formatting date, etc.

i know how structure test case. think of possible structure

describe( "australian full date format", function () {      describe( "time format", function () {         it("check if time format fetched correctly", function () {             expect(something).toequal(something);         });     });      describe( "adding 0 front", function () {         it("check if 0 added prior time", function () {             expect(something).toequal(something);         });     });      describe( "get local australian time", function () {         it("check if correct australian time fetched", function () {             expect(something).toequal(something);         });     });      it("check if date formatted correctly", function () {         expect(something).toequal(something);     }); }); 

if in right direction how move forward point onward. quite confused how write equivalent test case js code.

i create tests this:

describe("australian full date format", function() {   describe("#formatfulldate", function() {     it("should have format 'date/month/year hour:min'", function() {       //...     });   });    describe("#formattime", function() {     it("should have format 'hour:min'", function() {       //...     });   });    describe("#addzerotofront", function() {     describe("if whatever < 10", function() {       it("should add 0 front", function() {         //...       });     });     describe("if whatever >= 10", function() {       it("should return original without changes", function() {         //...       });     });   });    //... }); 

so used describe show function being tested. used describe conditions. used it test 1 feature of function. external objects (date in case) should stubbed test functions getutctimeoffset , getlocaltimefromaustraliatime.
