test_all failing on windows for current release - due to test_advection.py

[duncan]

I installed ANUGA from anuga-1.0beta_4733.tgz onto a windows box and got the following error;

Just run the latest version of ANUGA and got the same error.

I get it when I'm running on C:, but not when I run in Perlite. I'm also getting this log error;

I will try this with a more recent distribution.

The test that fails belongs to the advection module - which is hardly ever being used let alone kept up to date.

On Linux platforms it is excluded from the test because of weave.

However, it is interesting that the error can be reproduced on Windows by going to the advection folder and running test_advection.py - likewise it can be reproduced by checking out the repository on the C-drive and running test_all as Duncan noticed.

HOWEVER - on the network drive, when running test_all.py, test_advection is not run at all. That is a mystery!

I have included some print statements in the advection module and the test to see if it gets called on other platforms.

Duncan, can you please run test all and see if it gets called as it should?

Thanks

got test_advection running from test_all

Disabled the offending test, commented the logging info out (as this causes errors in the test suite as well) and finally decided to exclude test_advection.py on all platforms for the time being. See changeset:4796

It is there to revive whenever someone needs to. I have flicked this ticket to Stephen as he can decide whether to revive it.
