I want to use weld-se for unit testing CDI. However, I am stuck with this problem that Weld cannot resolve beans. I created a mini-project to demonstrate the problem with gradle for building.
I have the following files in the <project-root> folder:
./build.gradle
./src/main/java/cdi/Book.java
./src/main/resources/META-INF/beans.xml
./src/test/java/cdi/BookTest.java
./src/test/resources/META-INF/beans.xml
The content of each file is listed below.
build.gradle
apply plugin: 'java'
repositories {
mavenCentral()
}
dependencies {
compile 'org.jboss.weld.se:weld-se:2.0.4.Final'
testCompile 'junit:junit:4.11'
}
Book.java
package cdi;
public class Book {
private String title;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
BookTest.java
package cdi;
import org.jboss.weld.environment.se.Weld;
import org.jboss.weld.environment.se.WeldContainer;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class BookTest {
private static Weld weld;
private static WeldContainer weldContainer;
@BeforeClass
public static void setupClass() {
weld = new Weld();
weldContainer = weld.initialize();
}
@AfterClass
public static void teardownClass() {
weld.shutdown();
}
@Test
public void dummyTest() {
Book book = weldContainer.instance().select(Book.class).get();
book.setTitle( "foobar");
assertEquals("foobar", book.getTitle());
}
}
beans.xml(The two beans.xml under main/ and test/ are identical.)
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
version="1.1" bean-discovery-mode="all">
</beans>
When I build the project with gradle clean build, I get an error, which is listed below. I googled around, but couldn't make it work.
Thank you very much for your help.
