      Build step 'Publish Robot Framework test results' marked build as failure

       

      after an initial investigation  and not 100% sure the issue with a keyword we use alot in robot framework which has the following as argument:

      def disconnect(self):
              self.__save_current_index()
              try:
                  self.__switch_to_my_connection()
                  self.BI.run_keyword("SSHLibrary.Write Bare", chr(int(3)))
                  self.BI.run_keyword("SSHLibrary.Write Bare", "exit\n")
                  self.BI.run_keyword("SSHLibrary.Close Connection")
                  self.__my_index = None

      that the argument chr(int(3)) isnt considered textual somehow

      and may be the fix be around line 515 in the java code

      of course i may be wrong but when i run another test doesnt have this keyword it works fine

       

      the output xml is attached

          Hi,

          I just debugged with your output.xml file and I can indeed reproduce this. The issue is that twice in your output  XML you have an empty <arg></arg>(lines 4736 and 4793), which is not handled by the plugin.

          I can modify the parser to be able to handle these situations, but I'm more curious as to how you even ended up in a situation like this? As to my knowledge Robot Framework shouldn't produce empty <arg> tags at all.

          yes i understand you ......we tried to debug the reason behind this but i didnt find it ... but this is the case in our work environment ....so if the parser would be able to handle it that is great ....( cause now we are using rebot to snip out the part the is causing issues from the code)
