Arquillian，Tomcat 和 Jboss Seam 2

Question

我正在尝试在使用 Jboss Seam 2、Hibernate/JPa 和其他项目的 Web 项目中设置 Arquillian。我更新了我的 pom.xml 插入了以下代码和平：

<dependencyManagement>
    <dependencies>
        <!-- https://mvnrepository.com/artifact/org.jboss.arquillian/arquillian-bom -->
        <dependency>
            <groupId>org.jboss.arquillian</groupId>
            <artifactId>arquillian-bom</artifactId>
            <version>1.1.13.Final</version>
            <type>pom</type>
        </dependency>

    </dependencies>
</dependencyManagement>

...

  <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>7.0.42</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <version>7.0.42</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-logging-juli</artifactId>
            <version>7.0.42</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.eclipse.jdt.core.compiler</groupId>
            <artifactId>ecj</artifactId>
            <version>3.7</version>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>org.jboss.arquillian.container</groupId>
            <artifactId>arquillian-tomcat-embedded-7</artifactId>
            <version>1.0.0</version>
            <scope>test</scope>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.jboss.shrinkwrap.resolver/shrinkwrap-resolver-impl-maven -->
        <dependency>
            <groupId>org.jboss.shrinkwrap.resolver</groupId>
            <artifactId>shrinkwrap-resolver-impl-maven</artifactId>
            <version>2.2.6</version>
            <scope>test</scope>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.jboss.arquillian.junit/arquillian-junit-container -->
        <dependency>
            <groupId>org.jboss.arquillian.junit</groupId>
            <artifactId>arquillian-junit-container</artifactId>
            <version>1.1.13.Final</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>${junit.version}</version>
            <scope>test</scope>
        </dependency>

因此，在我的 pom.xml 中添加依赖项后的第二步创建了一个 Arquillian 测试 class，请参阅：

package com.projectx;

import org.jboss.arquillian.container.test.api.Deployment;
import org.jboss.arquillian.junit.Arquillian;
import org.jboss.seam.annotations.In;
import org.jboss.shrinkwrap.api.Archive;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.asset.EmptyAsset;
import org.jboss.shrinkwrap.api.spec.JavaArchive;
import org.jboss.shrinkwrap.api.spec.WebArchive;
import org.junit.Test;
import org.junit.runner.RunWith;

import com.projectx.MyService;

@RunWith(Arquillian.class)
public class MyServiceTest {

    @Deployment
    public static JavaArchive createTestArchive() {
        JavaArchive jar = ShrinkWrap.create(JavaArchive.class).addPackages(true, "com.projectx");
        return jar;
    }

    @In
    private MyService myService;

    @Test
    public void validateValue() {
       ReturnBean returnBean = myService.validateNow(null);         
    }

}

最后我尝试了运行我的测试 class 并且我注意到 "myService" 对象是空的，注入点没有工作，所以我得到了 NullPointerException。

我的观点是，我没有使用 ShrinkWrap 在 JavaArchive 中插入所有必要的东西。无论如何，在 arquillian 中创建我的 war 与 maven create 完全一样吗？

编辑 1：我在我的 pom.xml 中添加了以下依赖项：

<dependency>
            <groupId>org.jboss.arquillian.extension</groupId>
            <artifactId>arquillian-seam2</artifactId>
            <version>1.0.0.Beta1</version>
        </dependency>

并更改了以下依赖项的版本，因为与 arquillian-seam2 的兼容性：

<dependency>
            <groupId>org.jboss.arquillian.junit</groupId>
            <artifactId>arquillian-junit-container</artifactId>
            <version>1.1.1.Final</version>
            <scope>test</scope>
        </dependency>

<dependency>
                <groupId>org.jboss.arquillian</groupId>
                <artifactId>arquillian-bom</artifactId>
                <version>1.1.1.Final</version>
                <type>pom</type>
            </dependency>

但是当我尝试开始测试时，出现以下错误：

java.lang.IllegalStateException: duplicate factory for: org.jboss.seam.web.webSession (duplicate is specified in components.xml)

解决方法：我将容器从 apache-tomcat 更改为 jboss-as-5.1.

Answer 1

你必须使用 Seam 2 扩展来使注入通过 @In 在测试工作中 - https://github.com/arquillian/arquillian-extension-seam2。请记住，由于 Seam 2 不再处于活跃开发状态，因此扩展本身也不是。
