java - 将 Powermock 与 Weld 混合使用？

我们有一个项目使用

Weld-SE 用于依赖注入(inject)

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，我们想模拟定义它们的类。但是， PowerMock (特别是注释 @PrepareForTest )似乎与 Weld 的初始化困惑。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:

换句话说，它似乎对 beans.xml 进行了两次解析。有谁知道如何让这两个库一起玩得很好？

最佳答案

它似乎是一个 bug with the MockClassLoader 。

我提交了一个补丁，所以它可能会在 1.5.5 版本中修复。
