Over the past few weeks, we have been exploring a different approach to testing and evolving our Agentic Virtual Agents: an internal AVA created to support the validation of other AVAs.
During a 12-hour intensive review session, we reached some numbers that helped put the scale of the challenge into perspective:
🔹 Around 1,600 test conversations
🔹 6 AVAs reviewed
🔹 120 repeated validations of mandatory opening behavior
🔹 One critical routing journey improved from 17/30 to 39/40 successful executions
🔹 Five final behavior test suites completed with 84/84 criteria met
To put the volume into perspective, even if each conversation took only one minute to execute manually, that would represent more than 26 uninterrupted hours just running the interactions. This does not include reviewing results, documenting findings or making any improvements.
But the most valuable outcome was not simply running more tests in less time.
It was being able to observe how the same agent behaved across repeated executions, compare versions, identify regressions and find issues that could easily remain hidden in a few isolated manual tests.
Some of the lessons were surprisingly simple:
An agent being correct once does not mean it is reliable.
A good response does not always mean the expected action happened.
More instructions do not necessarily produce better behavior.
And a perfect score only matters when the test actually covers the entire journey.
The testing agent does not replace human judgment. Business knowledge, careful analysis and an understanding of the real customer journey are still essential. What it gives us is more evidence and a much better starting point for that analysis.
We are keeping the implementation details private for now, but I wanted to share the experience because it reinforced something important: agentic systems require a testing discipline designed for variability.
This project started as a practical way to make testing more scalable. It ended up changing how we understand and improve our AVAs.
Has anyone else in the community been exploring new ways to test Agentic Virtual Agents at scale? I would love to hear how you are approaching this challenge.
