-# Implementation Plan: Gatling Setup for Kubernetes Cluster Testing
-
-**Date:** 2026-04-30  
-**Branch:** `feat/NCS-57`  
-**Stack:** Scala 3.5.1, Gradle, Gatling 3.x (Scala DSL)
-
----
-
-## Decisions
-
-| Concern | Decision |
-|---|---|
-| Build tool | Gradle |
-| Language | Scala 3.5.1 |
-| Gatling API | Scala DSL (Gatling 3.x) |
-| Authentication | Bearer token via env var `GATLING_AUTH_TOKEN` |
-| Target base URL | Injected at runtime via Gradle project property `-PbaseUrl=...` |
-
----
-
-## Steps
-
-### Step 1 — `build.gradle` + `settings.gradle`
-
-Create `settings.gradle`:
-- Set root project name to `gatlin`
-
-Create `build.gradle`:
-- Apply `io.gatling.gradle` plugin (3.x)
-- Set `scalaVersion = '3.5.1'`
-- Configure `gatlingRun` task to pass `baseUrl` and `authToken` as JVM system properties so simulations can read them via `sys.props`
-
-Run command:
-```bash
-./gradlew gatlingRun -PbaseUrl=http://<cluster-service> -PauthToken=<token>
-```
-
----
-
-### Step 2 — Gradle wrapper
-
-Generate `gradlew` / `gradlew.bat` and `gradle/wrapper/gradle-wrapper.properties` (Gradle 8.x).  
-This ensures reproducible builds without a local Gradle installation.
-
----
-
-### Step 3 — Source layout
-
-Create the standard Gatling + Gradle directory structure:
-
-```
-src/
-  gatling/
-    scala/
-      simulations/       ← concrete simulation classes
-      base/              ← BaseSimulation.scala (shared protocol + auth)
-    resources/
-      gatling.conf       ← timeout / connection overrides
-      data/              ← CSV feeders (added per test as needed)
-      bodies/            ← request body templates (added per test as needed)
-```
-
-Update `.idea/Gatlin.iml` source roots to include `src/gatling/scala`.
-
----
-
-### Step 4 — `BaseSimulation.scala`
-
-`src/gatling/scala/base/BaseSimulation.scala`:
-
-- Reads `target.baseUrl` from `sys.props` (set by Gradle from `-PbaseUrl`)
-- Reads `gatling.authToken` from `sys.props` (set by Gradle from `-PauthToken` or env `GATLING_AUTH_TOKEN`)
-- Defines a shared `HttpProtocolBuilder`:
-  - base URL
-  - `Authorization: Bearer <token>` header on every request
-  - `Accept: application/json`
-  - connection keep-alive
-- Abstract class — concrete simulations extend it and inherit the protocol
-
----
-
-### Step 5 — `SmokeTestSimulation.scala`
-
-`src/gatling/scala/simulations/SmokeTestSimulation.scala`:
-
-- Extends `BaseSimulation`
-- Single virtual user, one `GET /healthz` request
-- Asserts: HTTP 200, response time < 2 000 ms
-- Purpose: verify end-to-end connectivity and auth before writing heavier tests
-
-This serves as the reference example for future simulations.
-
----
-
-### Step 6 — `gatling.conf`
-
-`src/gatling/resources/gatling.conf`:
-
-```
-gatling {
-  http {
-    enableGA = false
-  }
-}
-```
-
-Keeps telemetry off. Other defaults (timeouts, max connections) are left to Gatling's built-in values and can be overridden per-simulation in code.
-
----
-
-### Step 7 — `.gitignore` updates
-
-Add to `.gitignore`:
-```
-build/
-.gradle/
-results/
-```
-
----
-
-### Step 8 — `README.md` update
-
-Document:
-1. Prerequisites (Gradle wrapper handles everything — no local installs needed beyond a JVM)
-2. How to run: `./gradlew gatlingRun -PbaseUrl=... -PauthToken=...`
-3. How to add a new simulation (extend `BaseSimulation`, place in `simulations/`)
-4. Where reports are generated (`build/reports/gatling/`)
