Unit Testing With Flex Mojos

Monday, March 30. 2009

When I tried to update another project to flexmojos-maven-plugin 3.x I realized that I missed a step, when I wrote the upgrade instructions from flex-mojos 2.0.0 to the newer plugin. While the first project was at its very beginning with no Unit tests existing yet, the newer project had already quite some unit tests.

When running maven after I followed my own instructions I go this error:

[ERROR] <PROJECT PATH>/target/test-classes/TestRunner.mxml:[-1,-1] Unable to locate specified base class 'org.sonatype.flexmojos.unitestingsupport.TestApplication' for component class 'TestRunner'.


To solve this you have to replace this dependency

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

by the newer:

    <dependency>
      <groupId>org.sonatype.flexmojos</groupId>
      <artifactId>flexmojos-unittest-support</artifactId>
      <type>swc</type>
      <scope>test</scope>
      <version>3.1-SNAPSHOT</version>
    </dependency>

After that change the unit tests execute properly again.

    *Have you been able to see the stack traces of your tests? It seems to be a known problem that you can't see any useful output without running maven in -X mode...

    *You are right! I haven't noticed it yet, but in the surefire reports I am also missing the stack trace.

    However I prefer having a separate test runner project with a MXML applicaion containing the TestRunnerBase components. When a test case fails, I run this application from my IDE and I can not only see the stack trace but am also able to debug the test.

    *That's very interesting, I would really like to find out how you keep a separate project for the tests and still manage to reference the source from the application project in order to test it. Could you share your pom configuration tips for splitting the flex app and tests across 2 separate eclipse or maven multi-module projects?

    *As for library project that is not a big problem - just declare a dependency to this library.

    However I strongly discourage you to do so. You just would circumvent an essential key concept of Maven which is that only tested artifacts can be installed into the repository. You are opening the door to hell in case you separate unit tests from the code in Maven.

    *Actually to answer your questions for applications: Just configure the sourcePaths of your flexmojos-maven-plugin configuration in your flex unit project to point to the source path of your application. However this makes the flex unit project depending on a relative path to your application project, which violates another principle of a clean maven project.

    Really not recommended.

    *Great Blog. I have a question about skipping the tests.
    Is there an equivalent of -Dmaven.test.skip=true for the flexmojo which can be set in the pom.xml file.
    With version 3.2.0, tests are failing if the FlashPlayer is not in the PATH and I want to disable (skip) the tests in the pom.xml.

    *Hi Eric

    I am using flex-mojos 3.3.0 and -Dmaven.test.skip=true works here. Maybe a bug in 3.2.0?

    *<properties>
    <flex.sdk.version>3.3.0.4852</flex.sdk.version>
    <maven.test.skip>true</maven.test.skip>
    </properties>
