Firstly be aware that maven-surefire and tycho-surefire are completely different beasts.

maven-surefire is rather like Eclipse non-JUnit plugin testing. It tests locally built classes.

tycho-surefire is rather like Eclipse JUnit testing; but 'better' since it typically tests packaged JARs.

Unfortunately neither launches as an Eclipse launch so both can exhibit irritating errors for a newbie until you have successfully transliterated all your already working launch configuration and accommodated the eccentricities of the different test runner.

If you create intermediate files expect to have to create them as fully fledged independent projects; you can no longer create siblings of your (packaged) class files. I ended up writing a TestFileSystem to manage my intermediate classes for all four permutations of testing.

See GIT\org.eclipse.ocl\tests\org.eclipse.ocl.examples.xtext.tests\src\org\eclipse\ocl\examples\xtext\tests\TestFileSystem.java

Dependencies can be difficult. You may find the Tycho FAQ and entries such as

https://wiki.eclipse.org/Tycho/FAQ#How_do_I_install_the_org.eclipse.osgi.compatibility.state_fragment.3F

helpful.

Hello,

I’m new to tycho and I’m struggling to make some Junit tests running with maven/tycho from command line. They work fine from Eclipse IDE (Run As -> Junit Plug-in Test), but fail in command line. More details below:

- I have a plug-in: com.nxp.s32ds.cle.uct.core

- I created a fragment for unit tests: com.nxp.s32ds.cle.uct.core.tests

It contains unit tests which access the workspace (creates and removes projects).

The packaging is “eclipse-test-plugin” in the pom file.

- I use <tycho-version>0.26.0</tycho-version>

These two require other bundles to compile, which I specified in the parent pom.xml:

<repositories>

                                <repository>

                                                <id>neon-local</id>

                                                <layout>p2</layout>

                                                <url>${nexus.url}/content/repositories/neon3</url>

                                </repository>



                                <repository>

                                                <id>eclipse-updates-4.6</id>

                                </repository>



                                <repository>

                                                <id>uct</id>

                                                <layout>p2</layout>

                                                <url>jar: ${nexus.url}/builds/com.uct.updatesites-1.0.0-SNAPSHOT.zip!/</url>

                                </repository>

</repositories>

Everything works fine from Eclipse IDE, I am able to compile and execute the tests successfully.

From command line, “mvn clean verify” it fails in the test plugin with this message:

The class it doesn’t find com/nxp/swtools/sdkproject/EclipseProjectAdapterParams is part of “uct” repo specified in the parent pom.xml. However, it seems that the test runtime does not find it. There is no problem with that specified class, I tested and no class is found from that repo.

Any suggestions how to add the dependencies in the test runtime?

Thank you!
