JUnit Asserts

Cotta also extends JUnit to make assertion easier. These are release as cotta-asserts.

This is the final product of several attempts, including the one in DBFixture. It is an extension of the JUnit 4 assertion syntax, into Fluent Pattern like FEST-assert:http://fest.easytesting.org/assert/wiki/pmwiki.php but aim to complement JUnit assertions

How to Use Cotta Asserts

• Download cotta-assert.jar file from download page and add it to your test library.
• Declare a static field in the test case base class as public static final AssertionFactory ensure = new AssertionFactory();
• For all the tests that extends this test calss, you will now be able to write assertios like ensure.that(actual).eq(expected)

With this API, the assertions object returned by that method will be dependent on the type of the value you pass in, which means that for different type of value you will see different available assertion methods.

You can also check out the API JavaDoc

How to Extend the Assertion API

All the classes are public, which means that you can extend any of them to override the behavior of the assertion method. You can even create your own assertion factory and declare it as the ensure variable
