Promptfoo enables developers to run automated tests that simulate user interactions and potential attack scenarios such as prompt injection, jailbreak attempts, data leakage, and misuse of integrated tools. Promptfoo integrates with development workflows through command line interfaces, configuration files, and connections to version control and continuous integration pipelines. Its system evaluates prompts, models, and agent behaviors against defined test cases to identify vulnerabilities and performance issues during development. The software also provides reporting and remediation guidance that helps teams address findings and monitor AI application behavior across deployment environments.
