Changes to Tests/Data in OGS-6

Dear OGS developer,

I would like to draw your attention to the upcoming removal of the Tests/Data git submodule in OGS-6:

https://github.com/ufz/ogs/pull/2010

The folder Tests/Data will remain but its contents will be managed by Git LFS instead of a git submodule. This will ease the handling (especially in pull requests) of test data files. More information about git lfs at the community meeting next Tuesday or in the docs:

https://docs.opengeosys.org/docs/devguide/testing/test-data

Best,

Lars
