This constraint applies only to the Array 33 object itself, and is unaffected by length or array 34 index properties that may be inherited from its 35 prototype. 36 37 Author: christine (at) netscape.com 38 Date: 28 october 1997 39 40 */ 41 var SECTION = "15.4-2"; 42 var VERSION = "ECMA_1"; 43 startTest(); 44 var TITLE = "Array Objects"; 45 46 writeHeaderToLog( SECTION + " "+ TITLE); 47 48 var testcases = getTestCases(); 49 test(); 50 51 function getTestCases() { 52 var array = new Array(); 53 var item = 0; 54 55 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,16)] = 'hi'; arr.length", Math.pow(2,16)+1, eval("var arr=new Array(); arr[Math.pow(2,16)] = 'hi'; arr.length") ); 56 57 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,30)-2] = 'hi'; arr.length", Math.pow(2,30)-1, eval("var arr=new Array(); arr[Math.pow(2,30)-2] = 'hi'; arr.length") ); 58 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,30)-1] = 'hi'; arr.length", Math.pow(2,30), eval("var arr=new Array(); arr[Math.pow(2,30)-1] = 'hi'; arr.length") ); 59 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,30)] = 'hi'; arr.length", Math.pow(2,30)+1, eval("var arr=new Array(); arr[Math.pow(2,30)] = 'hi'; arr.length") ); 60 61 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,31)-2] = 'hi'; arr.length", Math.pow(2,31)-1, eval("var arr=new Array(); arr[Math.pow(2,31)-2] = 'hi'; arr.length") ); 62 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,31)-1] = 'hi'; arr.length", Math.pow(2,31), eval("var arr=new Array(); arr[Math.pow(2,31)-1] = 'hi'; arr.length") ); 63 array[item++] = new TestCase( SECTION, "var arr=new Array(); arr[Math.pow(2,31)] = 'hi'; arr.length", Math.pow(2,31)+1, eval("var arr=new Array(); arr[Math.pow(2,31)] = 'hi'; arr.length") ); 64 65 array[item++] = new TestCase( SECTION, "var arr = new Array(0,1,2,3,4,5); arr.length = 2; String(arr)", "0,1", eval("var arr = new Array(0,1,2,3,4,5); arr.length = 2; String(arr)") ); 66 array[item++] = new TestCase( SECTION, "var arr = new Array(0,1); arr.length = 3; String(arr)", "0,1,", eval("var arr = new Array(0,1); arr.length = 3; String(arr)") ); 67 // array[item++] = new TestCase( SECTION, "var arr = new Array(0,1,2,3,4,5); delete arr[0]; arr.length", 5, eval("var arr = new Array(0,1,2,3,4,5); delete arr[0]; arr.length") ); 68 // array[item++] = new TestCase( SECTION, "var arr = new Array(0,1,2,3,4,5); delete arr[6]; arr.length", 5, eval("var arr = new Array(0,1,2,3,4,5); delete arr[6]; arr.length") ); 69 70 return ( array ); 71 } 72 function test( array ) { 73 for ( tc=0; tc < testcases.length; tc++ ) { 74 testcases[tc].passed = writeTestCaseResult( 75 testcases[tc].expect, 76 testcases[tc].actual, 77 testcases[tc].description +" = "+ testcases[tc].actual ); 78 79 testcases[tc].reason += ( testcases[tc].passed ) ?
