Load Tests — SentryAgent.ai AgentIdP
Load tests are written for k6 and cover the three most performance-critical API flows.
Prerequisites
Install k6 on your machine (one-time):
# macOS
brew install k6
# Ubuntu / Debian
sudo gpg -k
sudo gpg --no-default-keyring --keyring /usr/share/keyrings/k6-archive-keyring.gpg \
--keyserver hkp://keyserver.ubuntu.com:80 --recv-keys C5AD17C747E3415A3642D57D77C6C491D6AC1D69
echo "deb [signed-by=/usr/share/keyrings/k6-archive-keyring.gpg] https://dl.k6.io/deb stable main" \
| sudo tee /etc/apt/sources.list.d/k6.list
sudo apt-get update && sudo apt-get install k6
# Windows (Chocolatey)
choco install k6
Environment Variables
Each script reads the following env vars:
| Variable | Default | Description |
|---|---|---|
BASE_URL |
http://localhost:3000 |
AgentIdP base URL |
CLIENT_ID |
(required for token test) | OAuth2 client_id for token issuance |
CLIENT_SECRET |
(required for token test) | OAuth2 client_secret |
AGENT_ID |
(required for rotation test) | Agent ID for credential rotation |
Export them before running:
export BASE_URL=http://localhost:3000
export CLIENT_ID=your-client-id
export CLIENT_SECRET=your-client-secret
export AGENT_ID=your-agent-id
Running Individual Scenarios
# Agent Registration — 100 VUs, 60s
k6 run tests/load/agent-registration.js
# Token Issuance — 1000 VUs, 60s
k6 run tests/load/token-issuance.js
# Credential Rotation — 50 VUs, 60s
k6 run tests/load/credential-rotation.js
Running All Scenarios (npm script)
npm run load-test
This runs all three scenarios sequentially, matching the same order as the CI pipeline.
Pass / Fail Thresholds
All scenarios enforce these thresholds (tests FAIL if any is breached):
| Metric | Threshold |
|---|---|
| p95 response time | < 500 ms |
| HTTP error rate | < 1 % |
k6 exits with a non-zero status code when any threshold is breached, making it safe to use in CI pipelines.
Results
k6 prints a summary table to stdout on completion. For HTML reports:
k6 run --out json=results.json tests/load/agent-registration.js
k6 report results.json
