我正在 src 文件夹中使用 moment.js 做一个小 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，它确实会失败（diff 返回 1），但是 Jasmine 给出了一个堆栈跟踪，这对我来说几乎没用，除非 Jasmine 本身有错误：
Error: Expected 1 to equal 0.

有人可以启发单元测试新手。也许我做错了什么。
