Question

我正在src-folder中使用moment.js做一个小小的Jasmine-standalone-demo。

describe("moment.js -> diff", function() {
    var start, end;
    it("leap year", function() {
        start = moment([2012, 1, 26]);
        end = moment([2012, 2, 4]);
        expect( end.diff(start, "days") ).toEqual(7);
    });
    it("winter-/summertime", function() {
        start = moment("2012-10-28T02:00:00+02:00");
        end = moment("2012-10-28T03:00:00+01:00");
        expect( end.diff(start, "hours") ).toEqual(0);
    });
});

第二个测试预计会失败，并且它会（diff返回1），但是Jasmine会给出一个堆栈跟踪，除非Jasmine本身有错误，否则接缝对我来说毫无用处：

Error: Expected 1 to equal 0.
    at new jasmine.ExpectationResult (http://localhost/jasmine/lib/jasmine-1.3.1/jasmine.js:114:32)
    at null.toEqual (http://localhost/jasmine/lib/jasmine-1.3.1/jasmine.js:1235:29)
    at null.<anonymous> (http://localhost/jasmine/spec/MomentSpec.js:11:38)
    at jasmine.Block.execute (http://localhost/jasmine/lib/jasmine-1.3.1/jasmine.js:1064:17)

    at jasmine.Spec.finish (http://localhost/jasmine/lib/jasmine-1.3.1/jasmine.js:2350:5)

有人可以启发一个单位测试新手。也许我做错了。

如果expect()块中有多个expect()，则堆栈跟踪会告诉您哪个it()函数失败了。

正如@zbynour所提到的，你必须在你的MomentSpec.js中找到你的第11行，第38位，找出来！
