junit4 - Running EMMA with JMockit and JUnit in Maven -

i have problem when running emma code coverage tool jmockit + junit in maven.

i have project , using jmockit mocking framework in it.

once run mvn test running without problem. that’s means jmockit initializing junit in proper way.

following way how define dependency jmockit , junit within pom (in exact order).

<dependency> <groupid>com.googlecode.jmockit</groupid> <artifactid>jmockit</artifactid> <version>1.7</version> </dependency> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <version>4.11</version> <scope>test</scope> </dependency>

but when check project code coverage emma, says

java.lang.illegalstateexception: jmockit wasn't initialized; check jmockit.jar precedes junit.jar in classpath (if using junit; if not, check documentation)

but think have configured emma plugin correctly , given below,

<build> <defaultgoal>install</defaultgoal> <plugins> <!—some other plugins here --> <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>emma-maven-plugin</artifactid> <version>1.0-alpha-3</version> <inherited>true</inherited> <configuration> <check> <classrate>100</classrate> <methodrate>100</methodrate> <blockrate>70</blockrate> <haltonfailure>false</haltonfailure> </check> </configuration> <executions> <execution> <goals> <goal>check</goal> </goals> </execution> </executions> <dependencies> <dependency> <groupid>com.googlecode.jmockit</groupid> <artifactid>jmockit</artifactid> <version>1.7</version> </dependency> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <scope>runtime</scope> <version>${junit.version}</version> </dependency> </dependencies> </plugin> </plugins>

can grab wrong there ?

i able figured out went wrong there. seems need junit utilize jmockit when work emma.

we can using maven-surefire-plugin.

we need add together next configuration pom.

<plugin> <groupid>org.apache.maven.plugins</groupid> <artifactid>maven-surefire-plugin</artifactid> <version>2.17</version> <configuration> <argline>-javaagent:${settings.localrepository}/com/googlecode/jmockit/jmockit/1.7/jmockit-1.7.jar</argline> <usesystemclassloader>true</usesystemclassloader> </configuration> </plugin>

note: create sure alter location of jmockit jar in above configuration.

further, not need have dependencies within emma plugin configuration. having them in dependencies section in pom (in exact order) enough.
