# eval-assertions-generate (Assertion Generation Example) You can run this example with: ```bash npx promptfoo@latest init --example eval-assertions-generate cd eval-assertions-generate ``` This example demonstrates valid configs for assertion generation in promptfoo. 1. A promptfoo config with prompts + assertions 2. A promptfoo config with just 1 prompt, and no assertions or test cases ## Getting Started Try the following options: Generate initial set of assertions (for a config that has none) ```bash promptfoo generate assertions --config examples/eval-assertions-generate/promptfooconfig-minimal.yaml -o test.yaml --type llm-rubric ``` Generate missing llm-rubric assertions (for a config that already has some) ```bash promptfoo generate assertions --config examples/eval-assertions-generate/promptfooconfig.yaml -o test.yaml --type llm-rubric ```
