Explanation

When executing unit tests directly instead of through zopectl, Plone 2.5.1/Zope 2.9.4 fails to set-up unit tests propeply. This is notable, since Windows users cannot run zopectl.

Something like this, I call mine test.bat:

@set ZOPE_HOME=C:\src\dev\Zope-2.9-bin
@set INSTANCE_HOME=c:\src\dev\instance\es30
@set PYTHON=c:\python24\python.exe
@set SOFTWARE_HOME=%ZOPE_HOME%\lib\python
@set CONFIG_FILE=%INSTANCE_HOME%\etc\zope.conf
@set PYTHONPATH=%SOFTWARE_HOME%
@set TEST_RUN=%ZOPE_HOME%\bin\test.py

"%PYTHON%" "%TEST_RUN%" --config-file="%CONFIG_FILE%" --usecompiled -vp %1 %2 %3 %4 %5 %6 %7

I can add that to the Plone Windows Installer.

Fix

Here is my test.bat

@echo off

REM Invoking unit test directly doesn't work anymore on Plone 2.5.1
REM See http://plone.org/documentation/error/attributeerror-test_user_1_

REM @set ZOPE_HOME=C:\src\dev\Zope-2.9-bin
set PYTHON=d:\python24\python.exe
set ZOPE_HOME=F:\workspace\plone-2.5.1\Zope-2.9.6\Zope
set INSTANCE_HOME=F:/workspace/plone-2.5.1/instance
set SOFTWARE_HOME=%ZOPE_HOME%\lib\python
set CONFIG_FILE=%INSTANCE_HOME%\etc\zope.conf
set PYTHONPATH=%SOFTWARE_HOME%
set TEST_RUN=%ZOPE_HOME%\bin\test.py

rem "%PYTHON%" "%TEST_RUN%" --config-file="%CONFIG_FILE%" --usecompiled -vp %1 %2 %3 %4 %5 %6 %7
"%PYTHON%" "%TEST_RUN%" --config-file="%CONFIG_FILE%" --usecompiled -vp --package-path=%INSTANCE_HOME%/Products/DataGridField Products.DataGridField
