Tycho integration test are not run (but Unit tests are..) - maven

Question

I have a multi module project with a plugin and fragment to test this plugin.
The build is done through maven/tycho. Maven v.3.8.4 and Tycho v2.6.0.
In the fragment I have 3 Unit and 1 Integration test, in the test folder:
test
├── CoreTestConstants.java
├── CoreUtils2Test.java
├── CoreUtils3Test.java
├── CoreUtilsIT.java
└── CoreUtilsTest.java
This is the pom of the fragment plugin:
<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"

<version>1.1.2</version>
<type>eclipse-plugin</type>
</dependency>
</dependencies>
</configuration>
</plugin>
</plugins>
</build>
</project>
The tycho-surefire-plugin is enabled in pluginManagement of the parent project:
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-surefire-plugin</artifactId>
<version>${tycho.version}</version>
</plugin>
The 3 Unit test are executed correctly, but the IT test is never run!
This is the relevant part of the output, when I run mvn clean verify inside the fragment project:

The execution it-test simply doesn't run anything! I have been wasting hours on this....
Thankyou for any help.

Answer 1

First of all, you shouldn't add any specific configuration if you follow the default conventions. Moreover, parameters like <testSourceDirectory>src</testSourceDirectory> are not read by the tycho surefire plugin. Moreover, there's no need to create products or features for what you need. The reason why it's not working it's because of a bug:
https://github.com/eclipse/tycho/issues/643
On a side note, I've updated the RELEASE notes
https://github.com/eclipse/tycho/pull/641
trying to document better the rationale behind the new goal (but, again, it does not work due to a bug)
