TapDate

TapDate is a mixin for the node-tap testing framework. It extends the tap test harness with new assertions for performing comparisons of date values.

Installation

TapDate requires that node-tap be installed as a peer dependency.

npm install tap tapdate

Usage

TapDate may be applied strictly to an individual test...

var test = require('tap').test;
var tapdate = require('tapdate');
 
test('some test', function (t) {
    tapdate(t);
 
    t.dateSame('2010-01-01 00:01:10', '2010-01-01 00:01:30');
    t.end();
});

... or to the tap framework as a whole.

var test = require('tap').test;
var Test = require('tap/lib/test');
require('tapdate')(Test.prototype);
 
test('some test', function (t) {
    t.dateBefore('2010-01-01 00:01:10', '2010-01-01 00:01:30');
    t.end();
});

If your node_modules tree is structured such that tapdate and tap exist on the same level, you can also apply to the whole framework by omitting the first argument:

var test = require('tap').test;
require('tapdate')();
 
test('some test', function (t) {
    t.dateNear('2010-01-01 00:01:10', '2010-01-01 00:01:11', 10);
    t.end();
});

Assertions

Date values may be Date objects, moment objects, or formatted date strings. If any value is unparsable as a date, the assertion will fail.

• dateAfter(found, wanted, [message]) - Asserts that the found date occurs after the wanted date.

• dateBefore(found, wanted, [message]) - Asserts that the found date occurs before the wanted date.

• dateSame(found, wanted, [unit], [message]) - Asserts that the found date is the same as the wanted date. A time unit (second, minute, hour, day, etc) may be passed to control how specific this assertion will test.

• dateNear(found, wanted, tolerance, [message]) - Asserts that the found date occurs within tolerance seconds of the wanted date.
