/** * Double Prompt Exact Scenario Reproduction Test * * This test file reproduces the EXACT scenario reported by the user for double prompt issues. * Following TDD methodology: * 1. Write failing tests with EXACT expected output strings * 2. Execute tests to capture actual output * 3. Update expected output with captured actual output * 4. Validate all tests pass with exact assertions * * USER REPORTED SCENARIO: * Input Terminal Output (what user reported): * [jsbattig@localhost ~]$ [jsbattig@localhost ~]$ * [jsbattig@localhost ~]$ whoami * jsbattig * [jsbattig@localhost ~]$ pwd * /home/jsbattig * [jsbattig@localhost ~]$ ls -la * [...exact ls output...] * [jsbattig@localhost ~]$ * * CRITICAL: All assertions must use exact string comparison (toBe()) - NO partial matching */ import { JestTestUtilities } from './integration/terminal-history-framework/jest-test-utilities';
