[josm-dev] unit testing and functional testing of plugins

[Jo]

Hi,

For some peace of mind and to avoid regression, while boldly adding
functionality, I'd like to encourage the student I'm mentoring to write
tests for the Mapillary plugin.

I found this folder, which contains tests:

https://josm.openstreetmap.de/browser/josm/trunk/test

Do tests which test a plugin go in a dedicated folder as part of the
plugin? I guess that would make most sense. Or is it possible to add a
condition which tests first for the availability of the plugin one wants to
test?

I tried to find this information here
https://josm.openstreetmap.de/wiki/DevelopersGuide/DevelopingPlugins, but
TDD is not mentioned there at all.
