How to add the plugin with my RCP application in the Tycho SWTBot test runtime

My RCP was created on a 3.x Eclipse and is now on 4.x using the compatibility layer. This is the setup that I have: I have two plugins: xyz-plugin and xyz-rcp-plugin. My RCP application is composed of these two plugins. I have a Test fragment (xyz-test) whose host plugin is xyz-plugin and contains SWTBot tests. My product configuration points to the application defined in the plugin.xml of xyz-rcp-plugin.

When I run the SWTBot Test via Eclipse, it all works ok. I point it to the correct application on the Main tab and it launches the correct one.

When I try to run it via Maven (using mvn integration-test), after the command to launch the UI for testing, no UI opens and it just reports saying there are test failures but it never actually even reaches the stage for testing my cases.

I feel this is happening because my test fragment only has xyz-plugin as its host and so knows its dependency but the application is actually contained in xyz-rcp-plugin so I am guessing it doesn't bring that plugin into the testing workspace. In fact, the test runs when I omit the <application> configuration in my pom file; it simple launches the default which is the Eclipse SDK.

So but how can I make the SWTBot test run my application, if the plugin with the application is not a dependency of the test plugin?


Below is my pom file for the test fragment,

Tycho does not automatically add the bundle defining the configured <application> to the test runtime - you need to manually ensure that this bundle is included.

One way to do this is to specify extra dependencies in the pom.xml of the test project. In this way, you can add bundles or even entire features (as always, including transitive dependencies) to the test runtime.

Example pom.xml snippet:

<plugin>
  <groupId>org.eclipse.tycho</groupId>
  <artifactId>target-platform-configuration</artifactId>
  <version>${tycho-version}</version>
  <configuration>
    <dependency-resolution>
      <extraRequirements>
        <requirement>
          <type>eclipse-plugin</type>
          <id>xyz-rcp-plugin</id>
          <versionRange>0.0.0</versionRange>
        </requirement>
      </extraRequirements>
    </dependency-resolution>
  </configuration>
</plugin>
