etcd-backup-restore makes use of three sets of tests - unit tests in each package, integration tests to ensure the working of the overall tool and performance regression tests to check changes in resource consumption between different versions of etcd-backup-restore.
Integration tests include the basic working of:
-
snapshotting: successfully upload full and delta snapshots to the configured snapstore according to the specified schedule
-
garbage collection: garbage-collect old snapshots on the snapstore according to the specified policy
-
defragmentation: etcd data should be defragmented periodically to reduce db size
-
http server: http endpoints should work as expected:
/snapshot/full: should take an on-demand full snapshot/snapshot/delta: should take an on-demand delta snapshot/snapshot/latest: should list the latest set of snapshots (full + deltas)
-
data validation: corrupted etcd data should be marked for deletion and restoration should be triggered
-
restoration: etcd data should be restored correctly from latest set of snapshots (full + deltas)
Each package within this repo contains its own set of unit tests to test the functionality of the methods contained within the packages.
These tests help check any regression in performance in terms of memory consumption and CPU utilization.
