Using DB unit to load DEMO data - maven

Question

I'm using the Maven DBUnit plugin to load test data for unit tests. I'd also like to use it for loading a different set of data to a different db for demo purposes. The dbunit plugin only allows for a single execution. Should I just create a separate pom or is there some trick that I can do to make this happen. (I.e., I'd like to simply do something like mvn load-demo-data).

Answer 1

you can execute a plugin several times if you like it depends just on the configuration you give in the pom:
<plugin>
<artifactId>maven-whatever-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<id>execution1</id>
<phase>test</phase>
<configuration>
....
</configuration>
<goals>
<goal>WhatEverGoalYouHave</goal>
</goals>
<phase>...</phase>
</execution>
<execution>
<id>execution2</id>
<configuration>
....
</configuration>
<goals>
<goal>WhatEverGoalYouHave</goal>
</goals>
<phase>...</phase>
</execution>
</executions>
</plugin>
You can also define a profile to control the execution which might the right choice for your demo data. The call you described mvn load-demo-data is not possible with maven, cause maven calls only a goal or lifecycle.

Answer 2

Use properties when configuring the database credentials
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>dbunit-maven-plugin</artifactId>
<version>${dbunit.plugin.version}</version>
<configuration>
<url>${db.url}</url>
<driver>${db.driver}</driver>
<username>${db.username}</username>
<password>${db.password}</password>
</configuration>
..
Then add a profiles section to your POM, controling the setting of these properties:
<profiles>
<profile>
<id>db1</id>
<properties>
<db.url>jdbc:h2:target/db1;AUTO_SERVER=TRUE</db.url>
<db.driver>org.h2.Driver</db.driver>
<db.username>user</db.username>
<db.password>pass</db.password>
</properties>
<profile>
<profile>
<id>db2</id>
<properties>
<db.url>jdbc:h2:target/db2;AUTO_SERVER=TRUE</db.url>
<db.driver>org.h2.Driver</db.driver>
<db.username>user</db.username>
<db.password>pass</db.password>
</properties>
<profile>
..
The profile cane be activated as follows to update two different databases
mvn -Pdb1 clean test
mvn -Pdb2 clean test
