用Jmockit与Eclemma

Question

我正在使用Jmockit在Eclipse中使用Jmockit来对我的代码和进行代码覆盖。出于某种原因我不是安倍才能得到报道。其他使用PowerMock的项目，可以很好地显示代码覆盖率。但在杰莫克特看来是有问题的。

例外情况如下：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Answer 1

以下解决方案对我有效：

1. 将jmockit版本升级到1.9。请注意，自1.9版以来，组id已从"org.jmockit“改为"com.googlecode.jmockit”。
2. 确保将jmockit依赖项放在pom中junit之前。

pom.xml中的依赖项如下所示：

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