The ImageMosaic acceptance tests were failing with 500 errors because they
referenced the old volume mount path /mnt/geoserver_data, which was changed
to /opt/geoserver_data in commit b33a27b9f6.
Changes:
- Update test_imagemosaic.py: Change all file paths from /mnt/ to /opt/
(6 occurrences across all test functions)
- Update acceptance_tests/README.md: Update sample data path documentation
to reflect the /opt/ mount location
The tests use external.imagemosaic REST endpoints to reference files that
must exist at the paths specified. With the old /mnt/ paths, GeoServer
could not find the sample data files, resulting in 500 Internal Server
Error responses.
- Add comprehensive ImageMosaic test coverage: direct directory, manual granules,
empty store workflows, and XML-based store creation
- Fix file path handling: use direct paths instead of file:// URLs for local files
- Update documentation to mention shared mount volume at /mnt/geoserver_data
- Add version testing examples (TAG=2.27.1.0, TAG=2.26.2.0) to README
Tests pass with datadir backend but show limitations with pgconfig backend.
Provides comprehensive test coverage for realistic ImageMosaic workflows.
