Usage of MySQL Maven Plugin for Integration Testing
First, add these two supplementary plugins to your pom.xml:
<project>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<goals>
<goal>reserve-network-port</goal>
</goals>
<configuration>
<portNames>
<portName>mysql.port</portName>
</portNames>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
<executions>
<execution>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>com.jcabi</groupId>
<artifactId>mysql-dist</artifactId>
<version>5.6.14</version>
<classifier>${mysql.classifier}</classifier>
<type>zip</type>
<overWrite>false</overWrite>
<outputDirectory>${project.build.directory}/mysql-dist</outputDirectory>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
[...]
</project>Then, configure jcabi-mysql-maven-plugin:
<project>
<build>
<plugins>
<plugin>
<groupId>com.jcabi</groupId>
<artifactId>jcabi-mysql-maven-plugin</artifactId>
<version>0.10.2</version>
<executions>
<execution>
<id>mysql-test</id>
<goals>
<goal>classify</goal>
<goal>start</goal>
<goal>stop</goal>
</goals>
<configuration>
<port>${mysql.port}</port>
<data>${project.build.directory}/mysql-data</data>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
[...]
</project>Make sure that you have perl installed on your build machine. It is required by MySQL scripts, which pre-configure an empty database before it can be used.
Now you need to know this temporary port number in your integration tests:
<project>
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<systemPropertyVariables>
<mysql.port>${mysql.port}</mysql.port>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
[...]
</project>In your integration tests connect to this on-demand instance of MySQL server:
public class FooITCase {
private static final String PORT = System.getProperty("mysql.port");
@Test
public void worksWithMysqlServer() {
// make a connection to
// jdbc:mysql:localhost:XXX/root?user=root&password=root
// where XXX is the port number
}
}User name, database name and password are always "root".
See the list of MySQL distributions supported out-of-the-box.
Since version 0.4 you can start MySQL and keep it running in foreground, until Ctrl-C is hit:
$ mvn jcabi-mysql:run
Cutting Edge Version
If you want to use current version of the product, you can do it with this configuration in your pom.xml:
<pluginRepositories>
<pluginRepository>
<id>oss.sonatype.org</id>
<url>https://oss.sonatype.org/content/repositories/snapshots/</url>
</pluginRepository>
</pluginRepositories>
<build>
<plugins>
<plugin>
<groupId>com.jcabi</groupId>
<artifactId>jcabi-mysql-maven-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
[...]
</plugin>
</plugins>
</build>
