# Measure

> Transcripts, evaluations, tests, analytics and credits: the words for reading back what an agent actually did, and what it cost to do.

| Term                                                                           | What it is                                                                                                                        |
| ------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------- |
| **[Transcript](/documentation/measure/transcripts)**                           | The record of one conversation the agent actually had, with every turn and trace.                                                 |
| **[Evaluation](/documentation/measure/evaluations)**                           | A criterion a model scores past conversations against, turning quality into a number you can track.                               |
| **[Test](/documentation/measure/tests)**                                       | A scripted conversation replayed against the agent, with checks asserting what it does.                                           |
| **[Analytics](/documentation/measure/analytics)**                              | Aggregate usage and cost: tokens, calls, conversations, unique users.                                                             |
| **[Credits](/documentation/account-management/billing/credits-pricing-table)** | The unit Voiceflow bills usage in.                                                                                                |
| **Test turn**                                                                  | One side of a scripted conversation: either what the user says, or the agent reply the checks assert against.                     |
| **Test check**                                                                 | One assertion about an agent turn. Compares the reply itself, or the behaviour behind it such as which tool was called.           |
| **Test run**                                                                   | One execution of a test, carrying how many of its checks passed. Runs are asynchronous, so poll until the status settles.         |
| **Transcript property**                                                        | A label you define once and then set on individual conversations, so your own outcome data can be filtered alongside Voiceflow’s. |
