E2E Testing for
Bland AI Voice Agents
Bland lets you scale outbound calls with AI. vspec makes sure your scripts, pathways, and tool integrations behave exactly as designed — on every deploy.
Test your Bland pathways
end to end.
Add your Bland inbound number
Paste the inbound phone number tied to your Bland agent. vspec dials it the same way a real caller would — no Bland API access required.
Script your test conversations
Define what the simulated caller says and what the Bland agent must say or do in return. Cover the happy path and every edge case.
Catch breaks before they ship
Run on demand or in CI. vspec calls your Bland number, transcribes the conversation, and returns a structured pass/fail result.
Every pathway. Every
branch. Every time.
Pathway branch testing
Bland's conversational pathways have many branches. vspec lets you write a test for each one — ensuring no branch is left untested before release.
Tool & webhook validation
Confirm that Bland's tool calls — calendar writes, CRM updates, SMS dispatches — fire at the right point and return the correct data.
Script regression detection
Even a small wording change in a Bland script can shift conversation outcomes. vspec detects these regressions automatically.
Outbound call simulation
Simulate the inbound leg of an outbound Bland campaign — verify the agent handles "yes," "no," and unexpected responses correctly.
Quality-gate your Bland
campaigns before launch.
