Why it matters
Validate and test AI prompt configurations using a simple YAML-based testing framework that allows developers to quickly set up and run test suites with inline or CSV-based test cases.
Outcomes
What it gets done

Overview
Simple Test
Simple Test is a promptfoo example that demonstrates YAML-based test configuration for evaluating LLM prompts. It includes both inline test definitions and CSV file input options, showing two approaches to structuring test cases within the promptfoo evaluation framework. Use this example when you need to understand promptfoo's configuration format. It provides a working configuration that demonstrates inline versus CSV-based test approaches.
What it does
Simple Test is a promptfoo example configuration that demonstrates how to set up and run prompt evaluation tests using YAML configuration files. It shows both inline test definitions and CSV-based test inputs.
When to use - and when NOT to
Use Simple Test when you need a working reference implementation to understand promptfoo's YAML configuration format. The example demonstrates inline versus CSV-based test approaches that you can adapt to your needs.
Inputs and outputs
You provide a YAML configuration file that defines your test cases either inline or references an external CSV file. The configuration specifies which prompts to test and what assertions to validate. When you run the evaluation, promptfoo executes the tests and outputs results showing which test cases passed or failed.
Getting started
Initialize the example with:
npx promptfoo@latest init --example simple-test
cd simple-test
Run the test suite with inline tests:
promptfoo eval
Or switch to CSV-based test inputs by editing the configuration to set tests: tests.csv, then run:
promptfoo eval --tests tests.csv
Who it's for
This example is for developers and prompt engineers who need a working configuration to understand the framework's structure.

You can run this example with:
npx promptfoo@latest init --example simple-test
cd simple-test
Usage
This example shows a YAML configuration with inline tests.
Run the test suite with:
promptfoo eval
Note that you can edit the configuration to use a CSV test input instead. Settests: tests.csv and try running it again, or run:
promptfoo eval --tests tests.csv
