Hi Paolo,
Can you execute the following commands in a python console:
import gdal
from osgeo.gdalconst import GA_ReadOnly
ds = gdal.Open('/path/to.tiff', GA_ReadOnly)
print(ds)

Which algorithm, dataset, parameters have you been trying?

Hi Paolo,
Each output type needs to be added to the tests, vector and raster data have been present since first merge. Today I added HTML (e.g. basic statistics). So the latest error should be gone.
I added a test for basic statistics with a float field. It would be great if you could check if you can add basic statistics for string fields.
FYI:
Please use one of the provided test files in the processing/testdata folder unless there is a good reason to use another one. These files include some NULL values, positive and negative values and therefore should point out some common problems when implementing algorithms.
Raster issues:
While raster outputs work fine here and on the linux test machine, there are problems on the mac machine - and it looks like they are the same as on your computer. To bad I do not have the possibility to reproduce this issue locally and to properly debug it. That would help to merge https://github.com/qgis/QGIS/pull/2761 .
Can you retry to run an algorithm which creates a tif, check if the output file is really in place and try to create a test for it and report the result back here.

Seems works fine now. Can we close this?
