How to Test a Game Save/Load System Before Release
A practical save-system test matrix for indie games covering slots, autosaves, checkpoints, migration, corrupt states and recovery.
Start with the real persistence flows
List the flows the shipped game actually supports: new save, manual load, overwrite, multiple slots, autosave, checkpoints, cloud sync or platform storage.
Test normal cases first
Create a fresh save, progress, save again, close the game, relaunch and load. Repeat on the exact target build and platform.
Test slot boundaries
Create, switch, overwrite and delete slots where supported. Make sure one slot cannot accidentally change another.
Test checkpoints and autosaves
Trigger autosaves repeatedly, interrupt normal gameplay after a save, and verify the loaded state matches the expected checkpoint.
Test version migration
If old saves must survive an update, define the old version, new version and expected migration result. Test the real migration instead of assuming serialization compatibility.
Test corrupt or incomplete states safely
Use controlled test copies. Verify the player gets a safe failure/recovery path instead of silent data loss or an endless crash loop.
Test recovery behavior
Verify backups, fallback saves or recovery prompts if the game provides them. Record what the user sees, not only what the code is supposed to do.
Retest after unrelated changes
Inventory, quest, world-state and progression changes can break persistence even when the save code itself was untouched.
Keep evidence tied to a build
Record build ID, platform, starting state, result and defect link. That makes regression testing repeatable.
What this checklist does not prove
It does not certify platform compliance, guarantee a bug-free release or replace source control, engine profilers, platform certification or legal requirements. Use it as a repeatable decision aid and verify the actual shipped build.
