Troubleshooting Parse Errors when running robot tests on Plone

Question

I'm really not sure what's wrong with my setup. The robot tests were added recently and we've seen them run successfully on another developer's OS X machine.

I'm attempting to run the same robot tests on an Ubuntu machine with Plone and Firefox installed. The package is https://github.com/collective/collective.academicprogrammes

I had to add plone.app.robotframework to the [test] section of my develop.cfg file. This is what my develop.cfg looks like now:

[sources]

collective.academicprogrammes = git git@github.com:collective/collective.academicprogrammes.git

[buildout]

test-packages = collective.academicprogrammes[test]

extends = buildout.cfg

extensions += mr.developer

eggs +=

  Products.DocFinderTab
  plone.reload
  collective.academicprogrammes

parts +=

  test
  diazotools
  zopeskel
  robot

always-checkout = force sources = sources auto-checkout = *

[test]

recipe = zc.recipe.testrunner

defaults = ['--exit-with-status', '--auto-color', '--auto-progress']

eggs =

  ${buildout:eggs}
  ${buildout:test-packages}

[zopeskel]

recipe = zc.recipe.egg

eggs =

  ZopeSkel
  Paste
  PasteDeploy
  PasteScript
  zopeskel.diazotheme
  zopeskel.dexterity
  zest.releaser
  ${buildout:eggs}

[robot]

recipe = zc.recipe.egg

eggs =

  Pillow
  ${test:eggs}
  plone.app.robotframework

After running bin/buildout -c develop.cfg to install everything I attempted to run bin/test -t robot I get the following errors:

File "parser.pxi", line 569, in lxml.etree._ParserContext._handleParseResultDoc (src/lxml/lxml.etree.c:74567) File "parser.pxi", line 650, in lxml.etree._handleParseResult (src/lxml/lxml.etree.c:75458) File "parser.pxi", line 590, in lxml.etree._raiseParseError (src/lxml/lxml.etree.c:74791)

File "parser.pxi", line 1450, in lxml.etree._parseDoc (src/lxml/lxml.etree.c:81590) bash: syntax error near unexpected token('

And it ends with:

Answer 1

The error is two-fold. One has to do with the fact that I installed a lightweight Linux OS that didn't include all the dependencies. Specifically I had to install libcanberra. To do this on Ubuntu I ran the following command 'sudo apt-get install libcanberra-gtk-module'. That was enough to fix the error about canberra-gtk-module.

The second issue was related to the version of Firefox used. It turns out that Selenium 2.34 is not compatible with Firefox 27 (the browser I'm using). see: http://selenium.googlecode.com/git/py/CHANGES

There are two options, upgrade Selenium to 2.40.0

OR

run robot browser tests against Firefox 25.

I opted to get Firefox 25 and use it when running tests.
