unit tests inside OpenWebBeans</h1>
+<p>One could argue that unit tests are harder to write when your instances are managed
by a container. 
+However this is only true if the booting of said container is uncharted territory. 
+But lets assume the container control is taken cared of handily. Well then it can be quite
the breath of fresh air to test code 
+that leverage dependency injection.</p>
+<p>Here comes the good news. Testing OpenWebBeans and CDI in general (and actually
many other Java EE frameworks) 
+is in a good state as of today and testing frameworks are reaching a pretty decent level
of maturity. Stay with us and 
+we will compare the pros and cons with 
+the different strategies. </p>
+<h3 id="good-practice">Good Practice</h3>
+<p>We won't go in to detail on how to properly use unit tests or integration tests
in your project. However so called "Whitebox Testing" is 
+discouraged. Using whitebox testing is often critizied regardless but with frameworks that
leverage 
+proxies it's simply not something you should attempt. Any reflection trick would likely miss
the mark and modify the proxy.
+Instead focus on functional tests and structure your code with high cohesion so that testing
the public methods get's the job done.
+Remember to add beans.xml and other resources to your to your test path.</p>
+<h3 id="start-small-with-plain-tests">Start small with plain tests</h3>
+<p>Testing code that leverage CDI does not differ much from using CDI in your project.
You should start with just a plain pojo 
+in your project and likewise a plain unit test. Only when you need context should you upgrade
the pojo to a CDI managed instance.
+Still this does not mean you automatically need something more then plain unit test. But
when you need the container to act on your
+instances (for example to trigger <code>@PostConstruct</code>) then go ahead
and upgrade the test to be CDI aware.</p>
+<h3 id="cdi-aware-tests">CDI aware tests</h3>
+<p>In OpenWebBeans we use JUnit as testing framework. For not having to deal with the
container details each time you can
+simply write a JUnit test which extends the <code>org.apache.webbeans.test.AbstractUnitTest</code>
base class.</p>
+<p>Lets look at how to write a unit test which e.g. tests a method invocation on a
specific CDI bean.</p>
+<p>The first thing we obviously need is the CDI bean which should get tested:</p>
+<div class="codehilite"><pre><span class="p">@</span><span class="n">RequestScoped</span>
+<span class="n">public</span> <span class="n">class</span> <span
class="n">BeanUnderTest</span>
+<span class="p">{</span>
+    <span class="n">public</span> <span class="n">int</span> <span
class="n">meaningOfLife</span><span class="p">()</span>
+    <span class="p">{</span>
+        <span class="k">return</span> 42<span class="p">;</span>
+    <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+
+
+<p>And now let's write the unit test which calls this method:</p>
+<div class="codehilite"><pre><span class="n">public</span> <span
class="n">class</span> <span class="n">MySimpleTest</span> <span class="n">extends</span>
<span class="n">AbstractUnitTest</span>
+<span class="p">{</span>
+    <span class="p">@</span><span class="n">Test</span>
+    <span class="n">public</span> <span class="n">void</span> <span
class="n">testMeaningOfLife</span><span class="p">()</span>
+    <span class="p">{</span>
+        <span class="n">startContainer</span><span class="p">(</span><span
class="n">BeanUnderTest</span><span class="p">.</span><span class="n">class</span><span
class="p">);</span>
+        <span class="n">BeanUnderTest</span> <span class="n">instance</span>
<span class="p">=</span> <span class="n">getInstance</span><span
class="p">(</span><span class="n">BeanUnderTest</span><span class="p">.</span><span
class="n">class</span><span class="p">);</span>
+        <span class="n">Assert</span><span class="p">.</span><span
class="n">assertnotNull</span><span class="p">(</span><span class="n">instance</span><span
class="p">);</span>
+        <span class="n">Assert</span><span class="p">.</span><span
class="n">assertEquals</span><span class="p">(</span>42<span class="p">,</span>
<span class="n">instance</span><span class="p">.</span><span class="n">meaningOfLife</span><span
class="p">());</span>
+    <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+
+
+<p>That's all! You don't need even need to manually shut down the container after the
method.
+If you have multiple beans to test then pass all of them as argument to <code>startContainer(Class...);</code>.
+There are also startContainer variants which take a beans.xml. Also look at the other methods
of <code>AbstractUnitTest</code> for more useful features.</p>
