将Jmockit与Eclemma结合使用

问题描述：

我正在使用Jmockit将我的代码和Eclipse中的Eclemma插件结合起来以进行代码覆盖. 由于某些原因，我不希望获得这份报道.其他使用PowerMock，Eclemma的项目显示出很好的代码覆盖率.但是使用Jmockit似乎有一些问题.

I am using Jmockit to junit my code and Eclemma plugin in Eclipse for code coverage. For some reason I am not abe to get the coverage. Other project which uses PowerMock, Eclemma shows code coverage fine. But with Jmockit there seems to be some problem.

以下是例外:

答

以下解决方案对我有用:

The following solution worked for me:

将jmockit版本升级到1.9.请注意，群组ID已从"com.googlecode.jmockit"更改为"org.jmockit"，因为 1.9版
确保在pom中将jmockit依赖项放在junit之前

Upgraded the jmockit version to 1.9. Please note the group id has been changed to "org.jmockit" from "com.googlecode.jmockit" since version 1.9
Ensure you place the jmockit dependency before junit in your pom

pom.xml中的依赖项如下所示:

The dependencies in pom.xml looks like this:

      <dependency>
        <groupId>org.jmockit</groupId>
        <artifactId>jmockit</artifactId>
      </dependency>
      <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
      </dependency>
