Perhaps refactor some of this common stuff like you did with the other tests, as
it is duplicated in minified and non-minified.

I thought about doing that when I wrote this, but since two of the classes need
to have private names it didn't seen worth the effort.

+  String toString() => "string representation";
+}
+
+class _PrivateName {
+  String toString() => "string representation";
+}
+
+class _PrivateNameIterable extends IterableMixin {
+  Iterator get iterator => [1, 2, 3].iterator;
+}
+
+// A regexp fragment matching a minified name.
+final _minifiedName = r"[A-Za-z0-9]{1,3}";
+
+void main() {
+  group('with an object', () {
+    test('with a default [toString]', () {
+      expect(prettyPrint(new DefaultToString()),
+          matches(r"<Instance of '" + _minifiedName + r"'>"));
+    });
+
+    test('with a custom [toString]', () {
+      expect(prettyPrint(new CustomToString()),
+          matches(_minifiedName + r':<string representation>'));
+    });
+
+    test('with a custom [toString] and a private name', () {
+      expect(prettyPrint(new _PrivateName()),
+          matches(_minifiedName + r':<string representation>'));
+    });
+  });
+
+  group('with an iterable', () {
+    test("that's not a list", () {
+      expect(prettyPrint([1, 2, 3, 4].map((n) => n * 2)),
+          matches(_minifiedName + r":\[2, 4, 6, 8\]"));
+    });
+
+    test("that's not a list and has a private name", () {
+      expect(prettyPrint(new _PrivateNameIterable()),
+          matches(_minifiedName + r":\[1, 2, 3\]"));
+    });
+  });
+}
