+== What to know for tests
-As we've already covered in the [Subject reference](subject.html "Subject"), we know that a Subject is security-specific view of the 'currently executing' user, and that Subject instances are always bound to a thread to ensure we know _who_ is executing logic at any time during the thread's execution.
+As we've already covered in the link:/subject.html[Subject reference], we know that a Subject is security-specific view of the 'currently executing' user, and that Subject instances are always bound to a thread to ensure we know _who_ is executing logic at any time during the thread's execution.
This means three basic things must always occur in order to support being able to access the currently executing Subject:
-1. A `Subject` instance must be created
-2. The `Subject` instance must be _bound_ to the currently executing thread.
-3. After the thread is finished executing (or if the thread's execution results in a `Throwable`), the `Subject` must be _unbound_ to ensure that the thread remains 'clean' in any thread-pooled environment.

-Shiro has architectural components that perform this bind/unbind logic automatically for a running application. For example, in a web application, the root Shiro Filter performs this logic when [filtering a request](http://shiro.apache.org/static/current/apidocs/org/apache/shiro/web/servlet/AbstractShiroFilter.html#doFilterInternal-javax.servlet.ServletRequest-javax.servlet.ServletResponse-javax.servlet.FilterChain-).

+== Test Setup
So we know after creating a `Subject` instance, it must be _bound_ to thread. After the thread (or in this case, a test) is finished executing, we must _unbind_ the Subject to keep the thread 'clean'.
Luckily enough, modern test frameworks like JUnit and TestNG natively support this notion of 'setup' and 'teardown' already. We can leverage this support to simulate what Shiro would do in a 'complete' application. We've created a base abstract class that you can use in your own testing below - feel free to copy and/or modify as you see fit. It can be used in both unit testing and integration testing (we're using JUnit in this example, but TestNG works just as well):

+== Unit Testing
Unit testing is mostly about testing your code and only your code in a limited scope. When you take Shiro into account, what you really want to focus on is that your code works correctly with Shiro's _API_ - you don't want to necessarily test that Shiro's implementation is working correctly (that's something that the Shiro development team must ensure in Shiro's code base).
Testing to see if Shiro's implementations work in conjunction with your implementations is really integration testing (discussed below).

-Because unit tests are better suited for testing your own logic (and not any implementations your logic might call), it is a great idea to _mock_ any APIs that your logic depends on. This works very well with Shiro - you can mock the `Subject` interface and have it reflect whatever conditions you want your code under test to react to. We can leverage modern mock frameworks like [EasyMock](http://easymock.org/) and [Mockito](http://site.mockito.org) to do this for us.

We can leverage modern mock frameworks like http://easymock.org/[EasyMock] and http://site.mockito.org[Mockito] to do this for us.
But as stated above, the key in Shiro tests is to remember that any Subject instance (mock or real) must be bound to the thread during test execution. So all we need to do is bind the mock Subject to ensure things work as expected.
(this example uses EasyMock, but Mockito works equally as well):

You can mix and match this setup/teardown logic in each method manually or use the @Before and @After annotations as you see fit.

+== Integration Testing
Now that we've covered unit test setup, let's talk a bit about integration testing. Integration testing is testing implementations across API boundaries. For example, testing that implementation A works when calling implementation B and that implementation B does what it is supposed to.
You can easily perform integration testing in Shiro as well. Shiro's `SecurityManager` instance and things it wraps (like Realms and SessionManager, etc) are all very lightweight POJOs that use very little memory. This means you can create and tear down a `SecurityManager` instance for every test class you execute. When your integration tests run, they will be using 'real' `SecurityManager` and `Subject` instances like your application will be using at runtime.

The example code below looks almost identical to the Unit Test example above, but the 3 step process is slightly different:
-1. There is now a step '0', which sets up a 'real' SecurityManager instance.
-2. Step 1 now constructs a 'real' Subject instance with the `Subject.Builder` and binds it to the thread.

As you can see, a concrete `SecurityManager` implementation is instantiated and made accessible for the remainder of the test via the `setSecurityManager` method. Test methods can then use this `SecurityManager` when using the `Subject.Builder` later via the `getSecurityManager()` method.
Also note that the `SecurityManager` instance is set up once in a `@BeforeClass` setup method - a fairly common practice for most test classes. But if you wanted to, you could create a new `SecurityManager` instance and set it via `setSecurityManager` at any time from any test method - for example, you might reference two different .ini files to build a new `SecurityManager` depending on your test requirements.
Finally, just as with the Unit Test example, the `AbstractShiroTest` super class will clean up all Shiro artifacts (any remaining `SecurityManager` and `Subject` instance) via its `@AfterClass tearDownShiro()` method to ensure the thread is 'clean' for the next test class to run.
