How do I test a FiveM script before production?
Test a FiveM script on a clean staging server before it reaches production: run resmon idle and active to check performance, spam its interactions to confirm rate limits and validation hold, and — for anything touching money or items — fire concurrent duplicate actions and kill the server mid-transaction to check for duplication or drift. Passing a feature demo only shows a script works; these three tests show whether it survives production.
In one lineTesting a FiveM script before production means verifying its performance (resmon), its security (behavioral abuse testing), and, for economy scripts, its concurrency safety (race and crash testing) on a staging server before it runs with real players.
The longer answer.
A feature demo only proves a script does the thing it's supposed to do under ideal conditions — one player, clicking normally, on an idle server. None of the failures that actually hurt a live server show up that way: they show up under concurrent load, under repeated abuse, or under a mid-operation crash, which is exactly why each needs a deliberate test rather than a walkthrough.
The performance pass is the resmon test: load the resource on a clean staging server, record its idle cost for a minute, then use it hard for several minutes and record the sustained active cost, watching that it returns to idle once you stop. The security pass is behavioral: rapidly repeat its interactions to confirm rate limits hold, and attempt actions from a state that shouldn't allow them, such as off duty or out of range.
For anything touching money, items, or another limited resource, add the two concurrency tests: fire a burst of identical concurrent actions against a single account or item to confirm exactly one succeeds (the race test), and kill the server process mid-operation, repeatedly, to confirm the data reconciles afterward with zero drift (the crash test). A script that has never been through a kill-mid-transaction cycle has an unknown, not a good, crash story.
The pre-production test plan
| Test | What it proves | Pass condition |
|---|---|---|
| resmon idle/active | Performance cost at rest and under use | 0.00–0.02ms idle, under ~0.10ms active |
| Interaction spam | Rate limiting and state validation hold | No duplication, no action from an invalid state |
| Concurrent race test | Whether simultaneous actions can double-spend | Exactly one success from N concurrent attempts |
| Kill-mid-transaction test | Whether a crash mid-write corrupts data | Reconciliation drift of zero after repeated kills |
