The **Test** tab lets you keep a set of test conversations and run them against an agent whenever you change something. It is the difference between hoping a prompt change helped and knowing it did. The Test tab only appears if the **Early Access Program** is enabled for your environment. See **[Experimental features](./experimental-feature)**. *** ## Generating a suite **Generate suite** reads your agent prompt and writes test cases for you, grouped by what each one is probing. A generated test suite with cases grouped under Flow, Policy, Boundaries, Recovery and Actions The groups are worth understanding, because they are the things that actually go wrong on live calls: | Group | What it tests | | -------------- | -------------------------------------------------------------------- | | **Flow** | The conversation going as intended, including a clean refusal. | | **Policy** | The agent holding its line when the caller is wrong about something. | | **Boundaries** | Difficult callers, such as someone threatening to hang up. | | **Recovery** | Getting back on track after confusion or interruption. | | **Actions** | The agent actually doing the thing, not just talking about it. | **Regenerate tests** replaces the suite. **Add test case** writes one yourself. *** ## Running tests **Run** executes the whole suite. Each case also has its own run control, so you can re-run just the one you are working on. **Setup context** supplies the context values the tests run with, so cases that depend on a name or an order number behave like a real call. *** ## Building tests from real calls The best test cases are conversations that already went wrong. Open a call in **[Calls](./call)** and use **Create test from call** on the Summary tab. The conversation becomes a case on this tab. You can also reach past calls from the **Test Agent** panel and resume from any point in one. When something goes wrong on a live call, turn that call into a test before you fix the prompt. Then you can prove the fix worked, and you will notice if a later change breaks it again. *** ## Improve an agent from a call Testing tells you something broke. **Train your agent** is how you fix it, using a real conversation as the evidence. This one is not gated. **Train your agent** works whether or not Experimental Features are enabled. You can reach it three ways: * **Improve agent** on a call's Summary tab in **[Calls](./call)**. * The **Test Agent** panel, which lists recent calls you can review. * Ending a browser test call, which drops you straight into it. The panel puts the call transcript on the left and a feedback box on the right. Describe what should have happened in plain language. You can also click any agent message in the transcript to comment on that specific turn, and those comments are sent along with your overall feedback. **Get Recommendations** then proposes prompt changes. ### Reviewing the changes Recommendations never apply silently. They open in a **Prompt changes** window first. The Prompt changes window showing a proposed addition to the agent prompt in green, with Reject All and Accept All in the footer Green is added text and red is removed. Changes are numbered, and **Previous** and **Next** step through them. You can reject any single change to keep the original wording. **Accept All** applies everything. If you rejected some, the button counts what is left, such as **Accept 1 Change**. Accepting only updates the prompt in the editor. Click **Save** on the agent for the change to take effect on real calls. Create a test from the call before you accept a recommendation. Then run the suite afterwards and you will know whether the fix worked. *** ## Where to go next * Change the prompt and settings you are testing in **[Agents](./agent)**. * Find the calls worth turning into tests in **[Calls](./call)**.
