Question

我有一个基于CDI的项目，它包含两个模块。核心模块有一些类需要注入Web项目的另一个模块。

主要关注的是代码很好并能够注入。但是JUNIT测试用例失败了。还有一点需要注意，如果我运行两个模块的父项目，JUNIT正在按预期运行。如果我运行模块特定，则抛出如下错误。

错误日志：

看到openejb，我想你正在与tomee合作：

我对这台服务器进行的原始测试给我的印象是，如果不进行任何大规模编码，测试工作就会产生令人难以置信的事情。这似乎有效，直到某一点。但它不是很可靠。

对我而言，使用tomee构建UnitTests最有希望的方法是使用ApplicationComposer本身。示例请参阅：smaller test 和bigger test with extra module

使用ApplicationComposer，您可以随意构建Testcontainer。

另一个问题，你真的需要使用OpenEjb，还是只想用它来进行嵌入式测试？如果选择也可以是Weld，也许可以看一下cdiunit。
