Hi,
Can someone tell me how to test active objects against multiple databases? I want to unit test my plugin (or at least my AO code) against all the major databases: MySQL, MS-SQL, Oracle, Postgres.
I see that there is something called "DynamicJdbcConfiguration" which according to the JavaDoc is: "A JDBC configuration that can be configured through either system properties or a configuration file." Does anyone have an example of how to use this "DynamicJdbcConfiguration" for multiple databases?
Many thanks,
-Bjarni

Hey Bjarni,
first you should probably read this first document, but I'm sure you have. This explains the configuration of the testing framework for a single database, and also mentions some important information relating to @NameConverters that should be used when testing your plugin.
Now if you want to test against multiple databases, I suggest you use the following strategy, which is used both in the AO lib and the AO plugin itself:
This should get you started. Running your tests should be as simple as running mvn install -P'database'.
Some things to note:
I hope that clarifies things a bit. Don't hesitate to comment if you need more info, I'll be happy to provide.
YOu can actually override the host, user, schema, etc. <profile> <id>db-postgres</id> <dependencies> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>9.3-1100-jdbc41</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.18.1</version> <configuration> <systemPropertyVariables> <ao.test.database>postgres</ao.test.database> <db.url>jdbc:postgresql://rds-db-xxxxx-us-east-1.rds.amazonaws.com:5432/test</db.url> <db.schema>public</db.schema> <db.username>user</db.username> <db.password>secret</db.password> </systemPropertyVariables> </configuration> </plugin> </plugins> </build> </profile>

According to the presentation of Jason Hinch on ActiveObjects (Slides available here: https://developer.atlassian.com/display/DOCS/Atlascamp+2011+-+Using+Active+Objects+for+Rapid+Plugin+Development) you have to use the DynamicJdbcConfiguration class in Jdbc annotation and set the database via a property.
@Jdbc(DynamicJdbcConfiguration.class) public class DatabaseTest { // }
To test with oracle database -Dao.test.database=oracle

Thanks Julien,
I suspected that DynamicJdbcConfiguration was the way to go but I need more info...
How do I tell the DynamicJdbcConfiguration where my database is (URL, user&pass)? And how would I test all the databases in one go? Do you use maven profiles? Can you give us an example of how you set the tests up?
Best regards and thanks again,
