Specifying --resource-types gives IndexError: list index out of range

[rgarner]

har2locust --resource-types document,xhr performance/an_undergraduate_student_joins.har > performance/an_undergraduate_student_joins.py

yields

Removing the --resource-types param generates the script. Also, adding the default har2locust --resource-types xhr,document,other performance/an_undergraduate_student_joins.har > performance/an_undergraduate_student_joins.py generates the script with no errors.

It looks like your HAR file has no resources of those types so after filtering, the entry list ends up empty and causes the error in another plugin. Maybe an explicit error should be thrown if there are no entries after executing an entries processor?

PR very welcome

@cyberw I would like to be able to contribute, but I'm mostly Ruby. My Python will need to get a lot better for me not to embarrass myself. I like that it got a little better after using this and Locust, and I love that Locust makes me want to make my Python good enough to do this, so I might be able to do it, but it might take cough some time...

[cyberw]

I understand :)
