38 * SUMMARY: Testing functions having duplicate formal parameter names
40 * SpiderMonkey was crashing on each case below if the parameters had
41 * the same name. But duplicate parameter names are permitted by ECMA;
42 * see ECMA-262 3rd Edition Final Section 10.1.3
44 * NOTE: Rhino does not have toSource() and uneval(); they are non-ECMA
45 * extensions to the language. So we include a test for them at the beginning -
47 //-----------------------------------------------------------------------------
50 var summary = 'Testing functions having duplicate formal parameter names';
54 var actualvalues = [];
56 var expectedvalues = [];
57 var OBJ = new Object();
58 var OBJ_TYPE = OBJ.toString();
61 * Exit if the implementation doesn't support toSource() or uneval(),
62 * since these are non-ECMA extensions to the language -
66 if (!OBJ.toSource || !uneval(OBJ))
76 * OK, now begin the test. Just checking that we don't crash on these -
80 var ret = eval(arguments.toSource());
81 return ret.toString();
83 status = inSection(1);
90 * Same thing, but preface |arguments| with the function name
94 var ret = eval(f2.arguments.toSource());
95 return ret.toString();
97 status = inSection(2);
105 var ret = eval(uneval(arguments));
106 return ret.toString();
108 status = inSection(3);
109 actual = f3(1,2,3,4);
115 * Same thing, but preface |arguments| with the function name
119 var ret = eval(uneval(f4.arguments));
120 return ret.toString();
122 status = inSection(4);
123 actual = f4(1,2,3,4);
130 //-----------------------------------------------------------------------------
132 //-----------------------------------------------------------------------------
138 statusitems[UBound] = status;
139 actualvalues[UBound] = actual;
140 expectedvalues[UBound] = expect;
149 printStatus(summary);
151 for (var i=0; i<UBound; i++)
153 reportCompare(expectedvalues[i], actualvalues[i], statusitems[i]);
