[GRASS-dev] gunittest test temporal dataset

Hi devs,

is there a way to test if a temporal dataset exists or not?
something like assertRasterExists

in the case it doesn't exist it could be useful?

Hi Luca,

Not that I am aware of. I use to parse output from t.list to check if a STDS exists…

Cheers
Stefan

Yes this was my idea too. Do you have an example?

Hi again,

Looking at my example I see that there is in fact a possibility to check existence of an STDS without t.list. See:
https://github.com/NVE/actinia_modules_nve/blob/036a4c85664a9015d5ca13ed6f40bdcc79bbfcb2/src/temporal/t.rast.reclass/t.rast.reclass.py#L294-L316

You could basically do:

import grass.temporal as tgis
# Initialize TGIS
tgis.init()
# Connect to TGIS DB
dbif = tgis.SQLDatabaseInterfaceConnection()
dbif.connect()

output_strds = tgis.factory.dataset_factory("strds", "MY_STRDS_NAME")
output_strds_exists = output_strds.is_in_db(dbif)
assertTrue(output_strds_exists)

Maybe worth considering to add a method for that in the unittest module!?!

Cheers,
Stefan
