我们已将Camunda安装为Wildfly8的模块。
一切正常，但是我需要一种模拟Java委托进行单元测试的方法（使用Arquillian）。
据我了解，org.camunda.bpm.engine.test.mock.Mocks可用于提供模拟的委托。
根据JavaDoc，我应该在我的流程引擎配置中注册MockExpressionManager。
我在这里找到了与MockExpressingManager类似的配置
https://github.com/camunda/camunda-bpm-assert/blob/master/camunda-bpm-assert-examples/src/test/resources/camunda.cfg.xml
但是在standalone-full.xml中配置了适用于wildfly的camunda模块：
<subsystem xmlns="urn:org.camunda.bpm.jboss:1.1">
<process-engines>
<process-engine name="default" default="true">
<datasource>
java:jboss/datasources/ProcessEngine
</datasource>
<history-level>
full
</history-level>
<configuration>
org.camunda.bpm.engine.cdi.CdiJtaProcessEngineConfiguration
</configuration>
<properties>
<property name="jobExecutorAcquisitionName">
default
</property>
<property name="isAutoSchemaUpdate">
true
</property>
<property name="authorizationEnabled">
true
</property>
<property name="jobExecutorDeploymentAware">
true
</property>
<property name="expressionManager">
org.camunda.bpm.engine.test.mock.MockExpressionManager
</property>
</properties>
但这不起作用，在Wildfly启动上，我看到了

如何正确地将此MockExpressionManager设置为配置？
还是可能有其他模拟Java委托的方法？
最佳答案
通过查看Camunda代码，他们期望传递对表达式管理器的引用。如果我不得不猜测，这将作为字符串传递。我可以想到的一种肮脏的处理方式是创建CdiJtaProcessEngineConfiguration的子类，该子类配置适当的表达式管理器，将该JAR部署到其模块中并将其插入。
就个人而言，我发现在直接Wildfly集成中它们的配置对我来说太紧了，因此选择直接在我的应用程序中配置它们的库。
