Pabot - Unable to run parallel robotframework tests

So, I'm working on a robotframework test project, and the goal is to run several test suites in parallel. For this purpose, pabot was chosen as the solution. I am trying to implement it, but with little success.

My issue is: after installing Pabot (which, I might say, I did by cloning the project and running "setup.py install", instead of using pip, since the corporate proxy I'm behind has proven an obstacle I can't overcome), I created a new directory in the project tree, moved some suites there, and ran:

pabot --processes 2 --outputdir pabot_results Login*.robot

Doing so results in the following error message:

enter image description here

2018-10-10 10:27:30.449000 PID:400 EXECUTING Suites.LoginUser

2018-10-10 10:27:30.777000 [PID:9676] [0] FAILED Suites.LoginAdmin

WARN: No output files in "pabot_results\pabot_results" Output: [ ERROR ] Reading XML source '' failed: invalid mode ('rb') or filename

Try --help for usage information. Elapsed time: 0 minutes 0.578 seconds

Upon inspecting the stderr file that was generated, I have this message:

enter image description here

Traceback (most recent call last): File "C:\Python27\Lib\site-packages\robotframework-3.1a2.dev1-py2.7.egg\robot\running\runner.py", line 22, in from .context import EXECUTION_CONTEXTS ValueError: Attempted relative import in non-package

Apparently, this has to do with something from the runner.py script, which, if I'm not mistaken, came with the installation of robotframework. Since manually modifying that script does not seem to me the optimal solution, my question is, what am I missing here? Did I forget to do anything while setting this up? Or is this an issue of compatibility between versions?

This project is using Maven as the tool to manage dependencies. The version I am running is 3.5.4. I am using a Windows 10, 64bit system; I have Python 2.7.14, and Robot Framework 3.1a2.dev1. The Pabot version is 0.44. Obviously, I added C:\Python27 and C:\Python27\Scripts to the PATH environment variable.

Edit: I am also using robotframework-maven-plugin version 1.4.0.8, if that happens to be relevant. Edit 2: added the error messages in text format.

Just in case anyone happens to stumble upon this issue in the future:

Since I can't use pip, and I tried a good deal of workarounds that eventually made things more unstable, I ended up saving my project and removing everything Python-related from my system, so as to allow me to install everything from scratch. In a Windows 10, 64bit system, I used:

  • Python 2.7.14

  • wxPython 2.8.12.1, win64, unicode, for py27

  • setuptools 40.2.0 (to allow me to use the easy_install command)

  • Robot Framework 3.0.4

  • robotremoteserver 1.1

  • Selenium2Library 3.0.0

  • and Pabot version 0.45.

I might add that, when installing the Selenium2Library the way I described above, it eventually tries to download some things from the pip repositories - which, if you have a proxy, will cause you trouble. I solved this problem by browsing https://pypi.org/simple/selenium/, manually downloading the 2.53.6 .tar.gz file, then extracting it and running setup.py install on the command line.

PS: Ideally, though, anyone should be able to use proxy settings from the command line (--proxy http://user:password@server:port) to get pip and then use it; however, for some reason, probably related to network security configurations that I didn't want to lose time with, this didn't work in my case.

Seems that you stumbled on a bug in the prerelease version of robot framework (3.1a2.dev1). Please install a release version of robot framework. For example 3.0.4.

I believe I've come across an issue similar when setting up parallel execution on my machine. Firstly I would confirm that pabot is installed using pip show robotframework-pabot.

Then you should define the directory your results are going to using -d. I then modified the name of the -o to Output.xml to make it easy to identify.

This is a copy of the code I use. Runs optimally with 8 processes

pabot --processes 8 -d results -o Output.xml Tests
