Maven/Tycho SWTBot Eclipse RCP

Question

I would like to run my UI Tests SWTBot with Maven/Tycho and Tycho can't get my .product. This my log:

!ENTRY org.eclipse.equinox.app 0 0 2017-12-02 16:36:32.573
!MESSAGE Product tychodemo.bundle.product could not be found.
***WARNING: Display must be created on main thread due to Cocoa restrictions.

!ENTRY org.eclipse.osgi 4 0 2017-12-02 16:36:32.760
!MESSAGE Application error
!STACK 1
...

This is my pom.xml:

<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">

        <groupId>org.eclipse.tycho</groupId>
        <artifactId>tycho-surefire-plugin</artifactId>
        <version>${tycho-version}</version>
        <configuration>
          <useUIHarness>true</useUIHarness>
          <useUIThread>false</useUIThread>
          <!-- use our product and application to launch the tests -->
          <product>tychodemo.bundle.product</product>
          <application>org.eclipse.e4.ui.workbench.swt.E4Application</application>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

Is it the right place to put my .product?

Thank you, Antoine

Can you post the entire stack trace for the "Application error"? Do the tests run from the IDE? — tkotisis, Dec 04 '17 at 16:01

The error seems to be indicative of an issue on the MacOS platform.

To launch the tests on a mac you need to specify the -XstartOnFirstThread command line option in a separate profile:

<profile>
  <id>macosx</id>
  <activation>
    <os>
      <name>macosx</name>
      <family>mac</family>
    </os>
  </activation>
  <properties>
    <ui.test.vmargs>-Xmx512m -XX:MaxPermSize=256m -XstartOnFirstThread</ui.test.vmargs>
  </properties>
</profile>
