如何在单元测试中测试CDI注入包含@inject和@any

Question

我想为这个类编写单元测试，如下所示。我不知道模拟或做任何事情来获取接口 ConnectDatabase:

  @Inject
  @Any
  private Instance<ConnectDatabase> allConnectType;


    public class DAOUtils {
  public DAOUtils() {
    System.out.println("Constructor...");
  }
  @Inject
  @Any
  private Instance<ConnectDatabase> allConnectType;
  @PostConstruct
  public void init() {
    System.out.println("PostConstruct...");
  }
  @PreDestroy
  public void destroy() {
    System.out.println("Destroy!");
  }
  public void query() {
    for (ConnectDatabase conn : allConnectType) {
      conn.connect();
    }
    System.out.println("query database...");
  }
}

接口的所有实现：

public interface ConnectDatabase {
   public void connect();
}

有人有任何想法吗？谢谢
