java - 将 Powermock 与 Weld 混合使用？

Question

我们有一个项目使用

• 用于依赖注入(inject)的 Weld-SE
• 调用本地库的静态本地方法

在编写单元测试时，为了测试与 native 库交互的托管 bean，我们希望模拟定义它们的类。然而，PowerMock (具体来说，注释 @PrepareForTest )似乎与 Weld 的初始化混淆。例如，如果我有以下内容:

@RunWith(PowerMockRunner.class)
@PrepareForTest(StaticNativeAPI.class)
public class Test {
  @Before
  public void setup() {
    WeldContainer wc = new Weld().initialize();
  }
}

然后 Weld 将无法初始化并出现以下错误:

org.jboss.weld.exceptions.DeploymentException: WELD-001423 Cannot enable the same alternative bean class [com.mycompany.AltBean in jar:file:/C:/Users/Me/.m2/repository/com/mycompany/project/version-SNAPSHOT/project-version-SNAPSHOT-tests.jar!/META-INF/beans.xml@8, com.mycompany.AltBean in jar:file:/C:/Users/Me/.m2/repository/com/mycompany/project/version-SNAPSHOT/project-version-SNAPSHOT-tests.jar!/META-INF/beans.xml@8] in beans.xml

换句话说，它似乎在解析 beans.xml 两次。有人知道如何让这两个库很好地协同工作吗？

Answer 1

它似乎是一个 bug with the MockClassLoader .

我提交了一个补丁，所以它可能会被 1.5.5 版本修复。
