-Testanza lets you write reusable tests by implementing simple interface.
-
-    public interface Tester<T> {
-      Test test(T item);
+Quackery lets you test if your code quacks like intended type.
+
+Try adding this Junit3-style code to test class.
+
+    @RunWith(AllTests.class)
+    public class JdkCollectionTest {
+      public static junit.framework.Test suite() {
+        return junit(newSuite("jdk collections quack like java.util.Collection")
+            .testThat(ArrayList.class, quacksLike(Collection.class))
+            .testThat(LinkedList.class, quacksLike(Collection.class))
+            .testThat(HashSet.class, quacksLike(Collection.class)));
+      }
     }
 
-Then you can build test suite for your particular class.
-
-    testThat(MyList.class, obeysCollectionContract());
-    testThat(MyList.class, obeysListContract());
-    testThat(MyList.class, isAssignableTo(Serializable.class));
-
-This will create a hierarchy of test for your class.

+Run it with junit test runner to see something like this.
 
-You can use built-in `Testers` or create your own.

-You can aggregate smaller `Testers` into more abstract contracts.
+You can use built-in contracts or create your own.
