Jacoco Sling Junit Integration-Test Execution - junit

One of our test classes extends RemoteBaseTest but Jacoco ignores it completely.
How can I make Jacoco work with Sling Integration Testing?
For Unit Tests everything works as expected.
We are using Adobe CQ 5.6.1.
I see that this issue has been resolved: sling-issue-tracker-2810
but unsure how to implement it - is it even included in the latest CQ-Version yet?
If not how do I manually add it?

I don't know what RemoteBaseTest is but I assume you are running a JUnit "proxy" test which talks to the Sling JUnit server-side tests subsystem and causes the actual tests to run on your CQ server.
If that's correct, the actual test code doesn't run in the client JVM that's running RemoteBaseTest, it runs in the server JVM that's running CQ. So it's on the server JVM that you need to setup Jacoco to collect coverage data.
If you're running some tests on the client JVM (like common JUnit tests) and some on the server JVM via the Sling testing tools, Jacoco has functions to merge coverage data coming from different JVMs. We have this as a work in progress in https://issues.apache.org/jira/browse/SLING-1803 , which is not fully integrated in Sling yet but should be adaptable to any version of CQ.

How to run espresso instrumentation test precondition on PC JVM?

I'm using espresso lib for android instrumentation tests. I also need to run precondition before tests (create account on web server, maybe some other data in future.)
I realized, that instrumentation test code actually runs on phone's JVM. I cannot run preconditions from phone, because of I'm planning to use jar-bundled test custom test framework where that precondition already implemented.
I there a way to run preconditions on PC JVM in android instrumentation test?

2 variants for JUnit execution: TestRunner & JUnitCore

There seem to be two approaches for invoking JUnit tests from the OS command shell:
java junit.textui.TestRunner <class-name>
and
java org.junit.runner.JUnitCore <class-name>
When do we use one versus the other?
Also, are there other ways to invoke Junit tests from the OS command shell?
JUnitCore is an entry point of JUnit - so if you want to run a test programmatically or of from some non-java script, I think, its the way to go for JUnit 4.
TestRunner is something a very old junit 3.x
Notice, that nowadays JUnit 5 is the latest available major release and it has yet another way to run the tests.
The question about different ways of running the tests from command line has been already answered Here so I can't add much to this.
However, I can comment on:
Also, are there other ways to invoke Junit tests from the OS command shell?
Nowadays in regular projects people do not run tests like this, instead they use one of build tools (Maven, Gradle for example) that among other things take care of tests.
So for example if you use maven, you can run mvn test and it will compile everything you need, including source code of tests, will take care about all test dependencies and will run all the tests with the help of build-in surefire plugin.
If you don't want to compile anything (assuming that all the code has been already compiled and all is set, you can use mvn surefire:test)
These build tools are also integrated with CI tools (like Jenkins, etc.) So this is considered to be a solved problem.
So unless you're doing something really different (like writing the IDE UI that should run test selected by user on demand or something) there is no really need to run tests with the options you've mentioned.

Forcing Eclipse to run JUnit tests in the same order that Maven runs them

I’m using Maven 3.2.3, SureFire 2.17, JUnit 4.11 and Eclipse Juno on Mac 10.9.5. I notice that when I run my JUnit tests via the command line
mvn test -Dtest=MyTest
the individual tests within the file “MyTest.java” run in a different order than when I run them in Eclipse (by right clicking the class name and selecting “Run As -> JUnit Test”). How do I get Eclipse to run the tests in the same order in which they are run on the command line?
Thanks, - Dave
The order of JUnit test runs are not guaranteed by design, as is mentioned in the JUnit FAQ page.This is done to promote the concept of test Independence, this will make sure that the tests will test their cases clearly and independently, and also ease maintainability.
This means that when you are running the tests in Eclipse, the orders are not guaranteed and keep changing. It's explained in "Can I change JUnit execution order?" on how you can possibly fix the order, even though its not a good practice.

run junit in intellij 12 where each test runs on its own JVM

I have a collection of unit tests, using single tones, so each test effects the other (unwanted behavior).
Can I run each test in its own JVM instance (fork=yes) using intellij 12 junit plugin?
I believe what your after is in Run/Debug Configurations.
Run --> Edit Configuration --> Defaults --> JUnit
in the top right of the configuration tab there is Fork Mode
On the defaults this can be changed to none or method, if you select a particular run configuration you can set to class as well

Hudson + JUnit + embedded GlassFish, how to provide domain configuration?

I'm using NetBeans and GlassFish 3.0.1 to create an EJB3 application. I have written a few Unit Tests, which get run via JUnit and make use of the embedded GlassFish. Whenever I run these tests on my development machine (so from within NetBeans), it's all good.
Now I would like to let Hudson do those tests. At the moment it is failing with lookup failure on a resource (in this case the datasource to a JPA persistance unit):
[junit] SEVERE: Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare method
[junit] java.lang.RuntimeException: javax.naming.NamingException: Lookup failed for 'mvs_devel' in SerialContext
After searching around and trying to learn about this, I believe it is related to the embedded GlassFish not having been configured with resources. In other words it's missing a domain.xml file. Right?
Two questions:
Why does it work with NetBeans on my dev box? What magic does NetBeans do in the background?
How should I provide the file? Where does the embedded GlassFish on the Hudson-box expect it?
Hudson is using the same Ant build-scripts (created by NetBeans).
I've read this post about instanceRoot and the EmbeddedFileSystemBuilder, but I don't understand enough of that. Is this needed for every TestCase (Emb. GF gets started/stopped for each bean-under-test)? Is this part of EJBContainer.createEJBContainer()? Again, why is it not necessary to do this when running tests on NetBeans?
Update
Following Peter's advice I can confirm: when running ant on a freshly checked out copy of the code, with the same properties as hudson is configured, the tests get executed!
10-1 it is a classpath issue as IDE's tend to swap paths in and out depending if you run normally or unittests.
Try running the tests on a commandline from a freshly checked out version from your SCM. Chances are you'll have the same error. Debugging on your local machine is a lot easier than on a remote machine.
When it builds reliably on the command line (in a separate directory) then it is time to move to hudson.
