I have the no node problem in the Validate Test Scripts from mainline link.
# There appears to be a configuration problem for the testcaseplugin. The reason could be one of the following: there are no testcases in subversion at the specified path...check some tests into Subversion and try again
# the trac.ini file is missing the config variable SubversionPathToTestCases under the section 'testManagementExtension'
# the current user is not allowed to access the subversion repository using the current trac acount
Error message if any specified here :
error fetching test case list
# An uspecified error occured...the most likely cause is either the path subversionpathtotestcases or repository_dir configuration values are set wrong in the trac.conf file. Error message included hopefully it will be useful
# Exception was: No node C:\Repositories\subcarto\RepoPrueba\PortletPrueba\testcases at revision 17
mi trac.ini has
repository_dir = C:\Repositories\subcarto\RepoPrueba?\PortletPrueba?\ (with this my browse code works ok, and let me see may trunk/tags/branches root, and of coures my testcases folder with a template and a testcase)
and
SubversionPathToTestCases?=/svn/subcarto/RepoPrueba/PortletPrueba/testcases
somebody already knows how to fix this error?
