                 <h1>Introduction</h1>
 <p>CDI is a revolution for Java EE world. This specification is the best one to avoid coupling between classes.</p>
 <p>This example simply aims to override bindings at runtime to simplify mocking work.</p>
 <p>It uses two kind of mocks:<br/>1) a mock with no implementation in the classloader<br/>2) a mock with an implementation in the classloader</p>
 <p>The mock answer from CDI is called <em>alternative</em>.</p>
 <p>Annotating <code>@Alternative</code> a class will mean it will replace any implementation if there is no other implementation or if it is forced (through <code>META-INF/beans.xml</code>).</p>
 <h1>Code explanation</h1>
 <h2>main code</h2>
 <p>We use an EJB <code>Jouney</code> to modelize a journey where the vehicle and the society can change. Here an EJB is used simply because it simplifies the test. A jouney wraps the vehicle and society information.</p>
 <p>We define then two interfaces to inject it in the <code>Journey</code> EJB: <code>Vehicle</code> and <code>Society</code>.</p>
 <p>Finally we add an implementation for <code>Scociety</code> interface: <code>LowCostCompanie</code>.</p>
 <p>If we don't go further <code>Journey</code> object will not be able to be created because no <code>Vehicle</code> implementation is available.</p>
 <p>Note: if we suppose we have a <code>Vehicle</code> implementation, the injected Society should be <code>LowCostCompanie</code>.</p>
 <h2>test code</h2>
 <p>The goal here is to test our <code>Journey</code> EJB. So we have to provide a <code>Vehicle</code> implementation: <code>SuperCar</code>.</p>
 <p>We want to force the <code>Society</code> implementation (for any reason) by our test implementation: <code>AirOpenEJB</code>.</p>
 <p>One solution could simply be to add <code>@Alternative</code> annotation on <code>AirOpenEJB</code> and activate it through the <code>META-INF/beans.xml</code> file.</p>
 <p>Here we want to write more explicit code. So we want to replace the <code>@Alternative</code> annotation by <code>@Mock</code> one.</p>
 <p>So we simply define an <code>@Mock</code> annotation for classes, resolvable at runtime which is a stereotype (<code>@Stereotype</code>) which replace <code>@Alternative</code>.</p>
 <p>Here is the annotation:</p>
 <pre><code>@Stereotype // we define a stereotype
 @Retention(RUNTIME) // resolvable at runtime
 @Target(TYPE) // this annotation is a class level one
 @Alternative // it replace @Alternative
 public @interface Mock {}
 </code></pre>
 <p>Note: you can add more CDI annotations after <code>@Alternative</code> and it will get the behavior expected (the scope for instance).</p>
 <p>So now we have our <code>@Mock</code> annotation which is a stereotype able to replace <code>@Alternative</code> annotation we simply add this annotation to our mocks.</p>
 <p>If you run it now you'll have this exception:</p>
 <pre><code>javax.enterprise.inject.UnsatisfiedResolutionException: Api type [org.superbiz.cdi.stereotype.Vehicle] is not found with the qualifiers
 Qualifiers: [@javax.enterprise.inject.Default()]
 for injection into Field Injection Point, field name :  vehicle, Bean Owner : [Journey, Name:null, WebBeans Type:ENTERPRISE, API Types:[java.lang.Object,org.superbiz.cdi.stereotype.Journey], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]]
 </code></pre>
 <p>It means the stereotype is not activated. To do it simply add it to your <code>META-INF/beans.xml</code>:</p>
 <pre><code>&lt;alternatives&gt;
   &lt;stereotype&gt;org.superbiz.cdi.stereotype.Mock&lt;/stereotype&gt;
 &lt;/alternatives&gt;
 </code></pre>
 <p>Note: if you don't specify <code>AirOpenEJB</code> as <code>@Alternative</code> (done through our mock annotation) you'll get this exception:</p>
 <pre><code>Caused by: javax.enterprise.inject.AmbiguousResolutionException: There is more than one api type with : org.superbiz.cdi.stereotype.Society with qualifiers : Qualifiers: [@javax.enterprise.inject.Default()]
 for injection into Field Injection Point, field name :  society, Bean Owner : [Journey, Name:null, WebBeans Type:ENTERPRISE, API Types:[org.superbiz.cdi.stereotype.Journey,java.lang.Object], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]]
 found beans:
 AirOpenEJB, Name:null, WebBeans Type:MANAGED, API Types:[org.superbiz.cdi.stereotype.Society,org.superbiz.cdi.stereotype.AirOpenEJB,java.lang.Object], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]
 LowCostCompanie, Name:null, WebBeans Type:MANAGED, API Types:[org.superbiz.cdi.stereotype.Society,org.superbiz.cdi.stereotype.LowCostCompanie,java.lang.Object], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]
 </code></pre>
 <p>which simply means two implementations are available for the same injection point (<code>Journey.society</code>).</p>
 <h1>Conclusion</h1>
 <p>With CDI it is really easy to define annotations with a strong meaning. You can define business annotations or simply technical annotations to simplify your code (as we did with the mock annotation).</p>
 <p>Note: if for instance you used qualifiers to inject societies you could have put all these qualifiers on the mock class or defined a <code>@SocietyMock</code> annotation to be able to inject the same implementation for all qualifiers in your tests.</p>

	<pre><code>javax.enterprise.inject.UnsatisfiedResolutionException: Api type [org.superbiz.cdi.stereotype.Vehicle] is not found with the qualifiers
	Qualifiers: [@javax.enterprise.inject.Default()]
	for injection into Field Injection Point, field name : vehicle, Bean Owner : [Journey, Name:null, WebBeans Type:ENTERPRISE, API Types:[java.lang.Object,org.superbiz.cdi.stereotype.Journey], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]]
	</code></pre>
	<p>It means the stereotype is not activated. To do it simply add it to your <code>META-INF/beans.xml</code>:</p>
	<pre><code><alternatives>
	<stereotype>org.superbiz.cdi.stereotype.Mock</stereotype>
	</alternatives>
	</code></pre>
	<p>Note: if you don't specify <code>AirOpenEJB</code> as <code>@Alternative</code> (done through our mock annotation) you'll get this exception:</p>
	<pre><code>Caused by: javax.enterprise.inject.AmbiguousResolutionException: There is more than one api type with : org.superbiz.cdi.stereotype.Society with qualifiers : Qualifiers: [@javax.enterprise.inject.Default()]
	for injection into Field Injection Point, field name : society, Bean Owner : [Journey, Name:null, WebBeans Type:ENTERPRISE, API Types:[org.superbiz.cdi.stereotype.Journey,java.lang.Object], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]]
	found beans:
	AirOpenEJB, Name:null, WebBeans Type:MANAGED, API Types:[org.superbiz.cdi.stereotype.Society,org.superbiz.cdi.stereotype.AirOpenEJB,java.lang.Object], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]
	LowCostCompanie, Name:null, WebBeans Type:MANAGED, API Types:[org.superbiz.cdi.stereotype.Society,org.superbiz.cdi.stereotype.LowCostCompanie,java.lang.Object], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default]
	</code></pre>
	<p>which simply means two implementations are available for the same injection point (<code>Journey.society</code>).</p>
	<h1>Conclusion</h1>
	<p>With CDI it is really easy to define annotations with a strong meaning. You can define business annotations or simply technical annotations to simplify your code (as we did with the mock annotation).</p>
	<p>Note: if for instance you used qualifiers to inject societies you could have put all these qualifiers on the mock class or defined a <code>@SocietyMock</code> annotation to be able to inject the same implementation for all qualifiers in your tests.</p>
