Today I created my first unit tests for Flex code using FlexUnit. Later I integrated the tests with the maven build using Flex Mojos. Flex-Mojos is a collection of maven-plugins created to work with Flex.

We have to use the Flex Compiler Plugin. This plugin is basically used to compile the source files and run tests. This plugin has 5 goals which are bound to different maven lifecycles. I chose to explicitly specify goals that I want maven to run. Maven has a default value for testSourceDirectory as src/test/java. For using Flex mojos, we have to specify testSourceDirectory as src/test/flex. Make sure all your tests are created under this directory.

	<build>
		<sourceDirectory>src/main/flex</sourceDirectory>
		<testSourceDirectory>src/test/flex</testSourceDirectory>
	        <plugins>
		    <plugin>
			<groupId>info.flex-mojos</groupId>
			<artifactId>flex-compiler-mojo</artifactId>
			<version>${flex-mojos.version}</version>
			<extensions>true</extensions>
			<executions>
			    <execution>
				<goals>
				    <goal>compile-swf</goal>
				    <goal>test-compile</goal>
				    <goal>test-run</goal>
				</goals>
			    </execution>
			</executions>
			<configuration>
			    <locales>
				<param>en_US</param>
			    </locales>
			    <contextRoot>/</contextRoot>
			</configuration>
		    </plugin>
  		</plugins>
	</build>

Next thing is to add Flex Unit dependency in the dependency section.

	<dependencies>
		<dependency>
			<groupId>flexunit</groupId>
			<artifactId>flexunit</artifactId>
			<version>0.85</version>
			<type>swc</type>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>flexunit.junit</groupId>
			<artifactId>flexunit-optional</artifactId>
			<version>0.85</version>
			<type>swc</type>
			<scope>test</scope>
		</dependency>
	</dependencies>

You would also need flash player installed on the build server. In case if you end up with OutOfMemory error, increase the heap size using MAVEN_OPTS in mvn.bat file.

SET MAVEN_OPTS=-Xmx128m

If you need more help, you can always refer the FlexUnit Example.
