+// 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);
