Adding Unit Tests

It is relatively simple to add unit tests for a plug-in in such a way that maven can run them as part of the build.

Here are the steps required in Eclipse:

• Create a new Fragment Project

  • File > New > Project... > Plug-in Development > Fragment Project
  • Set the project name to .tests
  • Change the location to the repository rather than the workspace (don't forget the project name)
  • Click "Next"
  • Make sure the Execution Environment points at the correct version of Java
  • Click the "Browse" button next to "Plug-in ID"
  • Select the plug-in to test and click "OK"
  • Finish

• In the newly created plug-in, add a new Package with the same name as the plug-in or something equally sensible.

  • Select the plug-in
  • File > New > Package
  • Enter the name and click "Finish"

• In the new Package create a class for adding test

  • Select the Package
  • File > New > Class
  • The class name must end in Test to be picked up by the automated build

• Add tests to the class

  • Add org.junit and org.mockito (if required) to the 'Required Plug-ins', under the Dependencies tab for the manifest

• Convert the new plug-in to a Maven project

  • Right-click on the plug-in and select Configure > Convert to Maven Project
  • Click "Finish"

• Add the new plug-in to the Parent POM

  • Select the pom.xml file in uk.ac.stfc.isis.ibex.client.tycho.parent
  • On the overview tab click "Add..." under the Modules section
  • Select the new plug-in from the list
  • Enable the "Update POM parent section in selected projects" option and click "OK"
  • Save it

• Edit the plug-in pom.xml file

  • Select the pom.xml file
  • Open the pom.xml tab
  • Change the packaging to eclipse-test-plugin
  • Remove the build section
  • Remove the groupID and version entries outside of parent
  • Save it

• Running the Maven build should now also run the tests

Example POM

An example test plug-in POM:

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <artifactId>tychodemo.bundle.tests</artifactId>
      <packaging>eclipse-test-plugin</packaging>
      <parent>
            <groupId>tychodemo</groupId>
            <artifactId>parent</artifactId>
            <version>1.0.0-SNAPSHOT</version>
            <relativePath>../tychodemo.parent</relativePath>
      </parent>
    </project>
