Comment #3 on issue 881 by [email protected]: Executing run multiple
times on RobotRunner fails
http://code.google.com/p/robotframework/issues/detail?id=881
DISCLAIMER: These suggestions are in my opinion hacks.
Can you set report generation off in your test environment (--report NONE)?
As the remove_keywords method should be related to report generation.
Hopefully there are no other errors..
One other thing that might make things work faster (I haven't tried this
one though and don't know if RobotRunner even is Serializable) could be to
serialize the whole RobotRunner instance (in memory and not to disc) before
running it and deserialize a clone for every test re-run.
