Sample Datasets
Add your own data to the test repository or use one of the sample datasets prepared for this purpose: https://github.com/fcrepo4-labs/fcrepo-sample-dataset (the files in "additional datasets" were created explicitly for import/export testing).
Import/Export Tool
The import/export tooling can be used to create an on-disk version of the resources loaded to a repository, and then to re-import those resources to an empty Fedora repository: https://github.com/fcrepo4-labs/fcrepo-import-export
...
This tool can be used to verify that the serialized resource set matches the resource set in the live repository after an export operation, and vice versa for import operations: https://github.com/fcrepo4-labs/fcrepo-import-export-verify
The sprint team also created a detailed test plan: Import - Export Test Plan. While this plan continues to be useful when considering features to test, at this stage it would be even more valuable to have feedback on how the tool meets real-world use cases based as much as possible on real data.
