HomeSAGOZEN QualityAutomated Preview Environment Testing
Ephemeral Staging Testing

Turn preview deployments into continuous quality checkpoints.

Vercel and Netlify make preview URLs easy. SAGOZEN Quality makes them safe. Automatically run regression suites against ephemeral URLs before merging to production.

The Challenge

Why Traditional Approaches Fail

Preview environments are deployed for every branch, but nobody tests them thoroughly because manual QA testing across 10+ open branch URLs is impossible.

The SAGOZEN Solution

Evidence-Based Release Assurance

Our webhook triggers self-hosted runners the second a preview environment is ready, executing cross-browser E2E sweeps and posting visual pass/fail badges directly back to your PR.

Core Solution Capabilities

Engineered capabilities designed to eliminate release friction.

01

Webhook-Driven Execution

Integrates with Vercel, Netlify, Cloudflare Pages, and custom Kubernetes preview webhooks.

02

Dynamic BaseURL Injection

Automatically detects target preview URLs without hardcoding environment config.

03

Parallel Runner Scaling

Spins up multi-container runners on demand for concurrent branch testing.

Implementation & Configuration

Clean, standard execution scripts with zero vendor lock-in.

preview-webhook.ts
typescript
import { handlePreviewDeployment } from '@sagozen/quality/preview';

export async function POST(req: Request) {
  const payload = await req.json();
  
  await handlePreviewDeployment({
    provider: 'vercel',
    deploymentUrl: payload.deployment.url,
    prNumber: payload.deployment.meta.githubPrId,
    suite: 'full-regression'
  });

  return Response.json({ success: true });
}

Frequently Asked Questions

What happens if a preview build takes time to deploy?

SAGOZEN Quality polls deployment health status automatically and only starts test execution once HTTP 200 health checks pass.

Can we test password-protected preview deployments?

Yes! Authentication headers or cookies can be injected securely via your self-hosted runner settings.
