Question

我想使用Arquillian对EJB进行单元测试。运行测试时，出现以下异常：

java.lang.RuntimeException: Could not create new instance of class org.jboss.arquillian.test.impl.EventTestRunnerAdaptor

这是有关企业编程课程的家庭作业。我确实有讲师的解决方案，但是由于相同的例外而失败了。我尝试过：

再次检查persistence.xml和arquillian.xml是否存在错误
根据建议here更改JUnit版本
确保Arquillian配置是我们要使用的：工作目录=“ $ MODULE_DIR $”的“ Wildfly Managed”。我也尝试过$ MODULE_WORKING_DIR $，因为IDE（intellij）建议这样做。

Persistence.xml ：

<?xml version="1.0" encoding="UTF-8"?>

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
             version="2.1">


    <persistence-unit name="JTA" transaction-type="JTA">

        <properties>
            <property name="wildfly.jpa.default-unit" value="true"/>
            <property name="connection.driver_class" value="org.h2.Driver"/>
            <property name="hibernate.connection.url" value="jdbc:h2:./target/db"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.show_sql" value="false"/>
        </properties>
    </persistence-unit>


    <persistence-unit name="DB" transaction-type="RESOURCE_LOCAL">

        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <properties>
            <property name="connection.driver_class" value="org.h2.Driver"/>
            <property name="hibernate.connection.url" value="jdbc:h2:./target/db"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.show_sql" value="true"/>
        </properties>
    </persistence-unit>
</persistence>

Arquillian.xml ：

<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">


    <container qualifier="wildfly" default="true">
        <configuration>
            <property name="jbossHome">target/downloaded_Wildfly/wildfly</property>
            <property name="outputToConsole">true</property>
        </configuration>
    </container>

</arquillian>

我要运行的测试类的一部分：

@RunWith(Arquillian.class)
public class CategoryEjbTest {

    @Deployment
    public static JavaArchive createDeployment() {
        return ShrinkWrap.create(JavaArchive.class)
                .addClasses(Category.class, Quiz.class, SubCategory.class, CategoryEjb.class, ResetEjb.class)
                .addAsResource("META-INF/persistence.xml");
    }

相关依赖项：

<!-- https://mvnrepository.com/artifact/junit/junit -->
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>
<!-- JEE_container for tests -->
<dependency>
    <groupId>org.wildfly</groupId>
    <artifactId>wildfly-arquillian-container-managed</artifactId>
    <version>8.2.1.Final</version>
    <scope>test</scope>
</dependency>

我要运行测试。取而代之的是，我得到以下堆栈跟踪，并且测试被忽略。
