Weld class not found when executing cdi-unit test

Question

I have a JEE project that is deployed on wildfly 10 smoothly.

I'm trying to write junit tests for my CDI beans with cdi-unit library (http://bryncooke.github.io/cdi-unit/)

My pom.xml looks like the following:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

<dependency>
     <groupId>org.jglue.cdi-unit</groupId>
     <artifactId>cdi-unit</artifactId>
     <version>4.0.1</version>
     <scope>test</scope>
</dependency>

However my sample test:

@RunWith(CdiRunner.class)
public class SampleTest {

   @Inject
   private Foo foo;

   @Test
   public void testFoo(){
      foo.bar();
   }
}

fails to initialize due to missing weld class:

CDI-UNIT manual says here that it automatically uses it's own version of Weld, hence there is no need to explicitly add any weld libraries in pom.xml.

Any help please?

You should include weld-se into your maven dependencies.

<dependency>
        <groupId>org.jboss.weld.se</groupId>
        <artifactId>weld-se-core</artifactId>
</dependency>

add as is fitting the version your wildfly-weld uses.

If you want more than the Simulation of the CDI-Container but also some have a realistic simulation of EJB-Functionality like persistence, transactionality, message driven beans, try ejb-cdi-unit It is derived from cdi-unit. There you can also find some example-projects which might help with your cdi-unit-issues.
