Subject: Replace trace-related fixtures with factories.
X-Git-Tag: live~3624^2~6
X-Git-Url: https://git.openstreetmap.org/rails.git/commitdiff_plain/15689af6bfa6220b9c539eb0717a3d75cc3c4799?hp=f7b4793c5048e7e939e7d614bed2c1b2473433d3

Replace trace-related fixtures with factories.

The mocking and stubbing in the controller tests is
unfortunate, but the models interact directly with the filesystem
using the trace id so that's hard to control any other way.
