// Tests the Object.defineProperties method - ES 15.2.3.7
// Note that the internal DefineOwnProperty method is tested through
// object-define-property.js, this file only contains tests specific for
// Object.defineProperties. Also note that object-create.js contains
// a range of indirect tests on this method since Object.create uses
// Object.defineProperties as a step in setting up the object.
// Try defining with null as descriptor:
try {
Object.defineProperties({}, null);
} catch(e) {
assertTrue(/null to object/.test(e));
}
// Try defining with null as object
try {
Object.defineProperties(null, {});
} catch(e) {
assertTrue(/called on non-object/.test(e));
}
var desc = {foo: {value: 10}, bar: {get: function() {return 42; }}};
var obj = {};
// Check that we actually get the object back as returnvalue
var x = Object.defineProperties(obj, desc);
assertEquals(x.foo, 10);
assertEquals(x.bar, 42);
