Git rebase reshapes your branch history. It rewrites commits to create an unbroken, linear log. When combined with tokenized test data, every commit in that history can store safe, synthetic values instead of raw production secrets. The result is a repository that is auditable, reproducible, and secure.
Tokenized test data is not less functional than real data. It is built to mirror structure and relationships. IDs, timestamps, email formats—every field keeps its shape. This keeps unit tests, integration tests, and CI runs consistent. By integrating tokenization at the commit level, you ensure that no regression changes slip through with hidden PII or credentials.
When you git rebase with updated tokenized data, you apply the same secure dataset across commits within the branch. This is useful in feature work where test datasets evolve alongside the code. Rebasing allows each commit to carry the correct version of the dataset, preserving accurate test results while eliminating risky artifacts that often remain in old commits.
