|
||
<p><strong>Why block-oriented timing?</strong><br />
|
||
Slots advance at a fixed rate (NTP-synchronized, 2s by default), so reasoning
|
||
about blocks and consensus intervals keeps assertions aligned with protocol
|
||
behavior rather than arbitrary wall-clock durations.</p>
|
||
<p><strong>Can I reuse the same scenario across runners?</strong><br />
|
||
Yes. The plan stays the same; swap runners (local, compose, k8s) to target
|
||
different environments.</p>
|
||
<p><strong>When should I enable chaos workloads?</strong><br />
|
||
Only when testing resilience or operational recovery; keep functional smoke
|
||
tests deterministic.</p>
|
||
<p><strong>How long should runs be?</strong><br />
|
||
The framework enforces a minimum of <strong>2× slot duration</strong> (4 seconds with default 2s slots), but practical recommendations:</p>
|
||
<ul>
|
||
<li><strong>Smoke tests</strong>: 30s minimum (~14 blocks with default 2s slots, 0.9 coefficient)</li>
|
||
<li><strong>Transaction workloads</strong>: 60s+ (~27 blocks) to observe inclusion patterns</li>
|
||
<li><strong>DA workloads</strong>: 90s+ (~40 blocks) to account for dispersal and sampling</li>
|
||
<li><strong>Chaos tests</strong>: 120s+ (~54 blocks) to allow recovery after restarts</li>
|
||
</ul>
|
||
<p>Very short runs (< 30s) risk false confidence—one or two lucky blocks don't prove liveness.</p>
|
||
<p><strong>Do I always need seeded wallets?</strong><br />
|
||
Only for transaction scenarios. Data-availability or pure chaos scenarios may
|
||
not require them, but liveness checks still need validators producing blocks.</p>
|
||
<p><strong>What if expectations fail but workloads “look fine”?</strong><br />
|
||
Trust expectations first—they capture the intended success criteria. Use the
|
||
observability signals and runner logs to pinpoint why the system missed the
|
||
target.</p>
