BuiltIn().get_variables().get('${EXECDIR}') not working getting AttributeError in robot framework 2.8.4

[gunaseelan Sakkarapani]

Code snippet:

from robot.api import TestCaseFile

from robot.api import TestSuite

from robot.api import TestSuiteBuilder

from robot.api import ResultWriter

from robot.api import logger

class SampleClient:

  def __init__(self,configFileName):

    self.testdetails = {}

    self.loglevel = "INFO"

     /* instead of  use os.getcwd and i want to use $EXECDIR builtin OS variable */

${EXECDIR}

An absolute path to the directory where test execution was started from. New in Robot Framework 2.1.

    self.logpath  = os.getcwd()

    self.reportpath = os.getcwd()

    self.logpath =  BuiltIn().get_variable_value('${ $EXECDIR}')

    self.reportpath  =  BuiltIn().get_variable_value('${ $EXECDIR}')

 getting following error

     self.logpath  = BuiltIn().get_variables().get('${EXECDIR}')

  File "/usr/local/lib/python2.5/site-packages/robot/libraries/BuiltIn.py", line 940, in get_variables

    return utils.NormalizedDict(self._variables.current, ignore='_')

    return self._namespace.variables

  File "/usr/local/lib/python2.5/site-packages/robot/libraries/BuiltIn.py", line 2656, in _namespace

    return self._context.namespace

AttributeError: 'NoneType' object has no attribute 'namespace'

       

def generateTests(self):

    self.testSuite = TestSuite(Constants.TEST_SUITE_NAME)

    self.testSuite.imports.library(Constants.LIBRARY_NAME,args=[self.testdetails])

    scriptname_list = self.getSASScript()

    if scriptname_list.__len__() == 0:return False 

    for script_name in scriptname_list:

      test = self.testSuite.tests.create(script_name)

      test.keywords.create(Constants.KEYWORD_EXECUTE, args=[script_name])

      test.keywords.create(Constants.KEYWORD_RESULT_SHOULD_BE, args=[Constants.TEST_PASSED])

    return True

def getScripts(self):

    script_list = []

    if os.path.islink(Constants.SCRIPT_LINK_PATH):

      script_list = [fn for fn in os.listdir(Constants.SCRIPT_LINK_PATH) if any([fn.endswith(ext) for ext in Constants.SCRIPT_EXTENSIONS])];

    return script_list

You didn't really explain what you are trying to do, but my guess is
that you are trying to create some kind of a custom test runner. If
that's the case, the reason for the above failure is that Robot's
variables are available only during test execution and in this case
execution hasn't yet started. The resulting error isn't too
informative. If you want, you can submit an enhancement request about
enhancing the error message.

In your case the easiest solution to this problem is using
os.getcwd(). The result ought to be exactly same as the value of
${EXECDIR}.

Cheers,
