Walkthrough
Reworks CreateProductSimulation: replaces single open-load with a multi‑phase open workload (atOnce, ramp, constant, rampPerSec, sustained constant), increases rates/durations, simplifies product→inventory flow to a doIf-based conditional update, adjusts pauses/logging, relaxes mean SLA to 2.0s and adds failedRequests constraint.

| Cohort / File(s) | Summary of Changes |
|---|---|
Gatling simulationgatling-tests/src/test/java/simulation/CreateProductSimulation.java |
Adds rampUsersPerSec import; replaces previous open-load with multi‑phase open workload: atOnceUsers, rampUsers, constantUsersPerSec (scaled), rampUsersPerSec (scaled), final constantUsersPerSec phase; increases ramp targets (3→50), constant targets (15→100) and extends duration (60s→180s). |
Scenario flow & timinggatling-tests/src/test/java/simulation/CreateProductSimulation.java |
Reworks scenario sequence: inlines JSON bodies for createProduct/createOrder, adds session-time log action, shortens/adjusts pauses (some fixed), sequences getProduct → doIf(session.contains("inventoryResponseBody")) { updateInventory } → createOrder; removes earlier inventory pre-checks/markAsFailed branches and related logs. |
Assertions & startup logginggatling-tests/src/test/java/simulation/CreateProductSimulation.java |
Changes startup health-check log to reference multiple users; relaxes mean response-time assertion from 1.5s to 2.0s; retains 95th percentile and failedRequests assertions with adjusted thresholds. |

Poem
Thump-thump—I hop from atOnce to ramp,
Users swelling like fields of clover and lamp.
I peek for inventory, update only if there,
Short pauses, long runs, logs whispered in air.
Mean time breathes two seconds—happy rabbit dance. 🐇
Pre-merge checks and finishing touches
❌ Failed checks (2 warnings)
| Check name | Status | Explanation | Resolution |
|---|---|---|---|
| Title Check | ⚠️ Warning | The title “handle more scenarios” is too vague and generic to clearly convey the substantial updates made to the Gatling simulation tests, such as introducing conditional inventory updates, multi-phase load profiles, adjusted timings, and enhanced logging in CreateProductSimulation. It does not reference the key elements of the changeset or the component being modified, making it difficult for a reviewer to grasp the primary purpose at a glance. | Please update the title to succinctly reflect the core changes, for example: “Enhance CreateProductSimulation with conditional inventory update and multi-phase load profile adjustments.” |
| Description Check | ⚠️ Warning | No pull request description was provided, so there is no context or summary of the implemented changes to guide reviewers or document the intent of the updates. This absence makes it hard to understand the purpose or scope of the modifications beyond examining the raw diffs. | Please add a brief description outlining the key updates—such as load profile default changes, the new conditional inventory workflow, logging enhancements, and updated assertions—to provide clear context for reviewers. |
