Overriding JTA into RESOUCE-LOCAL while Unit Testing


references

JTA

Let’s say you have a very simple persistence.xml looks like this.

<persistence-unit name="somePU" transaction-type="JTA">
  <jta-data-source>jdbc/someDS</jta-data-source>
  <exclude-unlisted-classes>false</exclude-unlisted-classes>
  <properties>
    <property name="javax.persistence.validation.mode" value="CALLBACK" />
  </properties>
</persistence-unit>

RESOUCE-LOCAL

You can, maybe you should, override it for unit testing. Following codes uses EclipseLink dependent API.

final Map<String, String> properties = new HashMap<>();
properties.put(PersistenceUnitProperties.TRANSACTION_TYPE,
               PersistenceUnitTransactionType.RESOURCE_LOCAL.name());
properties.put(PersistenceUnitProperties.JDBC_DRIVER,
               "org.apache.derby.jdbc.EmbeddedDriver");
properties.put(PersistenceUnitProperties.JDBC_URL,
               "jdbc:derby:memory:testDB;create=true");
properties.put(PersistenceUnitProperties.DDL_GENERATION,
               PersistenceUnitProperties.CREATE_ONLY);
properties.put(PersistenceUnitProperties.LOGGING_LEVEL,
               Level.FINE.getName());
properties.put(PersistenceUnitProperties.TARGET_SERVER,
               TargetServer.None);
ENTITY_MANAGER_FACTORY
    = createEntityManagerFactory("somePU", properties);

        final ServletHandler handler = new ServletHandler();
        SERVER.addServeltHandler(handler);

profiling maven tests


I have a very special case of profiling test cases.

Note that following example doesn’t work!

    <plugins>
      <plugin>

        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>

Simply failed. I found an issue which is marked as Fixed but this documentation update is what we should read.

There is a work-around for this problem.

<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <excludes>
            <exclude>**/*.java</exclude>
          </excludes>
        </configuration>
      </plugin>
    </plugins>
  </build>
  <profiles>
    <profile>
      <id>target13</id>
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
              <excludes>
                <exclude>NONE</exclude>
              </excludes>
              <includes>
                <include>com/googlecode/jinahya/test/Target13Test.java</include>
              </includes>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile> 
    <profile>
      <id>target14</id>
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>

          </plugin>
        </plugins>
      </build>
    </profile>
  </profiles>
</project>

It works.
