java - JUnit Testing EJB layer with embedded glassfish and Maven -

i have existing jee maven , eclipse project:

mainproject.ear +--project1.war +--project2.war +--ejb-proj.jar 

i have test profile unit testing ejb project, including read/write database jpa.

i have added dependency in pom.xml this:

        <!-- embedded glassfish -->         <plugin>             <groupid>org.glassfish</groupid>             <artifactid>maven-embedded-glassfish-plugin</artifactid>             <version>3.0-74b</version>             <configuration>                 <goalprefix>embedded-glassfish</goalprefix>                 <port>8080</port>                 <autodelete>true</autodelete>             </configuration>             <dependencies>                 <dependency>                     <groupid>mysql</groupid>                     <artifactid>mysql-connector-java</artifactid>                     <version>5.1.44</version>                 </dependency>             </dependencies> 

then have created test class:

@before public void setup() {      // instantiate container , context     ejbcontainer = ejbcontainer.createejbcontainer();     logger.info("opening container");     ctx = ejbcontainer.getcontext(); } 

these maven goals, in eclipse "skip test" unflagged:

clean compile package 

glassfish correctly started error missing jdbc driver.

class name wrong or classpath not set : com.mysql.jdbc.jdbc2.optional.mysqldatasource 

so, these questions:

1. why mysql dependency in embedded glassfish ignored ?
2. is correct start embedded container test class ? maybe better have started during test phases.
3. in end want container initialized ejb test, suppose have deploy ejb jar only. how can ?

for completeness, same maven goals skip test = true work. , .ear deployed in running container works too.
