The contents of the string are 27 implementation dependent, but are intended to represent the "date" 28 portion of the Date in the current time zone in a convenient, 29 human-readable form. We can't test the content of the string, 30 but can verify that the string is parsable by Date.parse 31 32 The toDateString function is not generic; it generates a runtime error 33 if its 'this' value is not a Date object. Therefore it cannot be transferred 34 to other kinds of objects for use as a method. 35 36 Author: pschwartau@netscape.com 37 Date: 14 november 2000 (adapted from ecma/Date/15.9.5.2.js) 38*/ 39 40 var SECTION = "15.9.5.3"; 41 var VERSION = "ECMA_3"; 42 var TITLE = "Date.prototype.toDateString()"; 43 44 var status = ''; 45 var actual = ''; 46 var expect = ''; 47 48 49 startTest(); 50 writeHeaderToLog( SECTION + " "+ TITLE); 51 52 53//----------------------------------------------------------------------------------------------------- 54 var testcases = new Array(); 55//----------------------------------------------------------------------------------------------------- 56 57 58 // first, some generic tests - 59 60 status = "typeof (now.toDateString())"; 61 actual = typeof (now.toDateString()); 62 expect = "string"; 63 addTestCase(); 64 65 status = "Date.prototype.toDateString.length"; 66 actual = Date.prototype.toDateString.length; 67 expect = 0; 68 addTestCase(); 69 70 /* Date.parse is accurate to the second; valueOf() to the millisecond. 71 Here we expect them to coincide, as we expect a time of exactly midnight - */ 72 status = "(Date.parse(now.toDateString()) - (midnight(now)).valueOf()) == 0"; 73 actual = (Date.parse(now.toDateString()) - (midnight(now)).valueOf()) == 0; 74 expect = true; 75 addTestCase(); 76 77 78 79 // 1970 80 addDateTestCase(0); 81 addDateTestCase(TZ_ADJUST); 82 83 84 // 1900 85 addDateTestCase(TIME_1900); 86 addDateTestCase(TIME_1900 - TZ_ADJUST); 87 88 89 // 2000 90 addDateTestCase(TIME_2000); 91 addDateTestCase(TIME_2000 - TZ_ADJUST); 92 93 94 // 29 Feb 2000 95 addDateTestCase(UTC_29_FEB_2000); 96 addDateTestCase(UTC_29_FEB_2000 - 1000); 97 addDateTestCase(UTC_29_FEB_2000 - TZ_ADJUST); 98 99 100 // 2005 101 addDateTestCase(UTC_1_JAN_2005); 102 addDateTestCase(UTC_1_JAN_2005 - 1000); 103 addDateTestCase(UTC_1_JAN_2005 - TZ_ADJUST); 104 105 106 107//----------------------------------------------------------------------------------------------------- 108 test(); 109//----------------------------------------------------------------------------------------------------- 110 111 112function addTestCase() 113{ 114 testcases[tc++] = new TestCase( SECTION, status, expect, actual); 115} 116 117 118function addDateTestCase(date_given_in_milliseconds) 119{ 120 var givenDate = new Date(date_given_in_milliseconds); 121 122 status = 'Date.parse(' + givenDate + ').toDateString())'; 123 actual = Date.parse(givenDate.toDateString()); 124 expect = Date.parse(midnight(givenDate)); 125 addTestCase(); 126} 127 128 129function midnight(givenDate) 130{ 131 // midnight on the given date - 132 return new Date(givenDate.getFullYear(), givenDate.getMonth(), givenDate.getDate()); 133} 134 135 136function test() 137{ 138 for ( tc=0; tc < testcases.length; tc++ ) 139 { 140 testcases[tc].passed = writeTestCaseResult( 141 testcases[tc].expect, 142 testcases[tc].actual, 143 testcases[tc].description + " = " + testcases[tc].actual ); 144 145 testcases[tc].reason += ( testcases[tc].passed ) ?
