Hi,

I just tried the new 'junit' command, works perfect for plain JUnit tests. Even Hudson picks up the build results
without a problem. This is great, thanks!

But running a 'Junit Plug-in Test' configuration (which runs perfectly from the IDE) fails with:

junit '-l' '/com.example.addressbook.uitests/Address Book UI Integration Tests.launch' '-o'
'/opt/hudson/jobs/addressbook_simple/workspace//test-reports /Address Book UI Integration Tests.xml'
ERROR: The application could not start. Details can be found in the log.
WARN: Process {0} terminated with exit status {1}.

This is not very helpful, what log is meant here? There is nothing in the buckminster headless log nor the debug output
nor the workspace log. Maybe the location of that log should be printed with the error message?

I'm using Buckminster 3.6 1.2.0.r11210.

Steps to reproduce:

- Get http://github.com/ralfebert/addressbook/commit/0426d37f5f5b8 50c2ac4ecc8c167426cfcae0097 ('Download source' link to
the upper right)
- Execute the following commands:

importtargetdefinition -A ${WORKSPACE}/features/com.example.addressbook.site/rcp.targe t
import '${WORKSPACE}/features/com.example.addressbook.site/site.cqu ery'
build
junit -l '/com.example.addressbook.tests/Addressbook Unit Tests.launch' -o '${WORKSPACE}/test-reports/Addressbook Unit
Tests.xml'
junit -l '/com.example.addressbook.uitests/Address Book UI Integration Tests.launch' -o
'${WORKSPACE}/test-reports/Address Book UI Integration Tests.xml'

Greetings,

Ralf

Hi Ralf,

That first message "The application could not start. Details can be found in
the log." comes from PDE itself. It typically indicates that one or more
bundles could not be resolved, mostly because of unresolved dependencies or
missing platform-specific fragments. You should find more information in the
log of the runtime workspace that PDE executes the tests in (e.g.
"${workspace_loc}/../junit-workspace" in the default launch configs).

The second message "Process {0} terminated with exit status {1}." comes from
Buckminster and isn't very helpful indeed. Could you please file a bug for
this last one?

Thanks,
Achim

thanks, I investigated this a bit more, it doesn't even get that far.
workspace/.metadata/.plugins/org.eclipse.pde.core/AddressBoo kUITests/*.log says:

!ENTRY org.eclipse.equinox.launcher 4 0 2010-02-21 20:25:48.793
!MESSAGE Exception launching the Eclipse Platform:

This is odd because a JUnit test runs without problems, and this Plug-in test is running with the exact same .target
file on the same platform in the IDE. Do I need to install something special into Buckminster (besides the core and pde
headless features?) I guess it's missing some dependency, but it doesn't give me a hint what might be missing...

Greetings,

Ralf

Hi Ralf,

Apart from the core and pde headless features, there's nothing you need to
install into Buckminster for JUnit testing.

Which version of the Eclipse IDE are you using? There have been some changes
regarding JUnit in Eclipse 3.6, so if you're using Eclipse 3.5 for
development and the latest Buckminster (based on 3.6) for headless builds,
there's a slight chance that the launch config needs to be adapted. Can you
please check that with a 3.6 IDE?

Also, please make sure that the "Clear the configuration area before
launching" option is selected, especially if you're using the same launch
config from both Eclipse 3.5 and headless 3.6. Otherwise, p2 might be
tempted to load bundles from locations that don't exist.

Cheers,
Achim

Hi Achim,

thanks for the hints. I'm running with 3.6M5 IDE and Buckminster 3.6 1.2.0.r11210, clearing the configuration area is on
as per default. Any ideas how I could get more console output from the launched test process?

Greetings,

Ralf

Hi Ralf,

I'm afraid I don't exactly know what's wrong here. I'll debug into the
launch process in the next evenings. I'll let you know as soon as I know
more.

Cheers,
Achim

Hi Ralf,

I tracked the problem deep down into the PDE code used for launching. It
does not collect all bundles that are relevant for the launch and as a
consequence the application cannot start. I am still trying to find out more
about this, but here's a workaround that worked for me, and it should also
work for you:

Copy the org.eclipse.pde.launching bundle from your Eclipse 3.6M5 IDE
(should be version 3.6.0.v20100120) into the plugins folder of your
buckmister headless installation. Then change the bundles.info file in the
configuration/org.eclipse.equinox.simpleconfigurator folder of your
buckminster headless. There should be a line that refers to the
pde.launching bundle. Simply change the version and path to the one you just
copied. After that, running the tests should work. Can you verify this?

In other words: We apparently package a newer version of the pde.launching
bundle than the one that is shipped with 3.6M5 and that version happens to
be broken for UI launching. I'll investigate. Thanks for reporting this.

Cheers,
Achim

FYI, I found out that recent changes in PDE launching code based on this
enhancement [1] have introduced this regression. See the last couple of
comments on this bug. The good news is that the PDE team seems to be
investigating this and we can have hope that upcoming versions of
Buckminster will work out-of-the-box again.

Cheers,
Achim

yes, this fixed it. Thanks a lot, finally I can run UI tests in headless fashion with acceptable amounts of
configuration work, this is really great.

After configuring Xvfb (virtual X11 server) this runs even without interfering with the main Display, very cool!

Greetings,

Ralf
