E2E Testing for
Synthflow Voice Agents
You built your no-code Synthflow assistant without writing a line of code. Make sure it actually works with vspec — automated call tests that catch regressions before your clients do.
No-code agent,
no-friction testing.
Add your Synthflow phone number
Copy the phone number from your Synthflow assistant and paste it into vspec. That's the only connection needed — no Synthflow API keys required.
Describe your test scenarios
Write what the caller says and what your Synthflow agent must do or say. Validate the whole workflow from greeting to wrap-up.
Automated results, every time
Run tests on demand or automatically. vspec dials your Synthflow assistant, records the full conversation, and returns a clear pass/fail verdict.
From intake to handoff —
fully tested.
Workflow regression testing
Synthflow workflows evolve. Any edit to actions, prompts, or integrations can break the flow. vspec catches regressions the moment they're introduced.
Integration action validation
Confirm that Synthflow's built-in integrations — CRM updates, calendar bookings, Zapier triggers — fire correctly during a call.
White-label quality assurance
Agencies using Synthflow for clients can run vspec to QA each assistant before delivery — ensuring every deployment meets spec.
Multi-language & persona testing
If your Synthflow assistant serves multiple languages or personas, vspec lets you run separate test suites for each configuration.
