# scenario-testing Runs end-to-end tests against live dependencies without mocks. Relies on genuine data scenarios as the reference point. - plugin · `type=plugin` · Claude Code · ★ 97 - Author: 2389-research - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/2389-research/claude-plugins/tree/HEAD/scenario-testing - Updated: 2026-10-21 - HTML: https://affpapa.org/en/nevibecode/plugins/scenario-testing ## What it does This plugin sets up end-to-end testing with zero mocks. Every run hits genuine external dependencies instead of simulated responses. Tests fail immediately whenever a live dependency goes down. Real data flows serve as the single source of truth for your application behavior. That leaves no room for fake test passes hiding runtime surprises before deployment. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-community ``` In the agent chat (not a shell): ```text /plugin install scenario-testing@claude-community ``` ## When to use it - verify application flows against live dependencies - eliminate mocks from end-to-end suites - execute scenario tests with authentic data ## Example prompts - Run end-to-end scenarios against real dependencies without mocks - Verify the user scenario using authentic data ## Source text · scenario-testing · MIT Below is the content of a third-party file.
