Injection not working properly in Arquillian Tests - strange errors - cdi

Question

I have a somewhat strange problem with Arquillian tests and CDI injections:
This bean works perfectly fine when it's being tested:
#RequestScoped
public class Greeter {
#Inject
protected GreetingProvider greetingProvider;
public String doGreeting(String greet) {
System.out.println("Information: greetingProvider=" + greetingProvider);
return String.format("%s, %s!", greetingProvider.getGreetingWord(), greet);
}
}
with the only exception, that in the following test case the method "testGreetingProviderInGreeterIsNotNull()" always fails
#RunWith(Arquillian.class)
public class GreeterTest {
#Deployment
public static WebArchive createDeployment() {
WebArchive deployment = ShrinkWrap.create(WebArchive.class)
.addClass(Greeter.class)
.addClass(GreetingProvider.class)
.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml") ;
return deployment;
}
#Inject
private Greeter greeter;
#Test
#InSequence(1)
public void testGreeterIsInjectedProperly() {
assertNotNull(greeter);
}
#Test
#InSequence(2)
public void getGreetingTest() {
String name = "John";
String expected = "Hello, " + name + "!";
String actual = greeter.doGreeting(name);
assertEquals(expected, actual);
}
#Test
#InSequence(3)
public void testGreetingProviderInGreeterIsNotNull() {
assertNotNull(greeter.greetingProvider);
}
}
I do not understand why, cause if the field greetingProvider were null also the second test method should fail.
What's my error?

I believe, but not 100% sure, it's because you're missing an arquillian.xml in your src/test/resources folder that should force the default protocol to Servlet 3. By default, in AS7/EAP6 the protocol is their JMX protocol. When you use their JMX protocol the RequestScope is not active for the interaction.
Your arquillian.xml should look like this:
<?xml version="1.0" encoding="UTF-8"?>
<arquillian xmlns="http://jboss.org/schema/arquillian"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
<defaultProtocol type="Servlet 3.0" />
</arquillian>
