The contents of the string are + implementation dependent, but are intended to represent the "date" + portion of the Date in the current time zone in a convenient, + human-readable form. We can't test the content of the string, + but can verify that the string is parsable by Date.parse + + The toDateString function is not generic; it generates a runtime error + if its 'this' value is not a Date object. Therefore it cannot be transferred + to other kinds of objects for use as a method. + + Author: pschwartau@netscape.com + Date: 14 november 2000 (adapted from ecma/Date/15.9.5.2.js) +*/ + +var SECTION = "15.9.5.3"; +var VERSION = "ECMA_3"; +var TITLE = "Date.prototype.toDateString()"; + +var status = ''; +var actual = ''; +var expect = ''; + + +startTest(); +writeHeaderToLog( SECTION + " "+ TITLE); + +// first, some generic tests - + +status = "typeof (now.toDateString())"; +actual = typeof (now.toDateString()); +expect = "string"; +addTestCase(); + +status = "Date.prototype.toDateString.length"; +actual = Date.prototype.toDateString.length; +expect = 0; +addTestCase(); + +/* + * Date.parse is accurate to the second; valueOf() to the millisecond. + * Here we expect them to coincide, as we expect a time of exactly + * midnight - + */ +status = "(Date.parse(now.toDateString()) - (midnight(now)).valueOf()) == 0"; +actual = (Date.parse(now.toDateString()) - (midnight(now)).valueOf()) == 0; +expect = true; +addTestCase(); + + + +// 1970 +addDateTestCase(0); +addDateTestCase(TZ_ADJUST); + + +// 1900 +addDateTestCase(TIME_1900); +addDateTestCase(TIME_1900 - TZ_ADJUST); + + +// 2000 +addDateTestCase(TIME_2000); +addDateTestCase(TIME_2000 - TZ_ADJUST); + + +// 29 Feb 2000 +addDateTestCase(UTC_29_FEB_2000); +addDateTestCase(UTC_29_FEB_2000 - 1000); +addDateTestCase(UTC_29_FEB_2000 - TZ_ADJUST); + + +// 2005 +addDateTestCase(UTC_1_JAN_2005); +addDateTestCase(UTC_1_JAN_2005 - 1000); +addDateTestCase(UTC_1_JAN_2005 - TZ_ADJUST); + + + +//----------------------------------------------------------------------------- +test(); +//----------------------------------------------------------------------------- + + +function addTestCase() +{ + new TestCase( + SECTION, + status, + expect, + actual); +} + +function addDateTestCase(date_given_in_milliseconds) +{ + var givenDate = new Date(date_given_in_milliseconds); + + status = 'Date.parse(' + givenDate + ').toDateString())'; + actual = Date.parse(givenDate.toDateString()); + expect = Date.parse(midnight(givenDate)); + addTestCase(); +} + + +function midnight(givenDate) +{ + // midnight on the given date - + return new Date(givenDate.getFullYear(), givenDate.getMonth(), givenDate.getDate()); +} + |
