 The interface does not execute contracts in the browser. Generated commands run locally through `soroban-testkit`, keeping contract tests deterministic and offline as required by the core project.
 
+## Workflow Testing & Verification
+
+Comprehensive component testing ensures complete coverage of interactive command builder combinations:
+
+- **Coverage Workflow**: Component tests verifying report format selections (`html`, `lcov`, `text`), `--open` flag toggling, path quoting, and combined option configurations.
+- **Limits Workflow**: Component tests verifying `--contract` path resolution (including paths with spaces), custom function identifiers (`--fn`), and ramp parameters (`--ramp`).
+- **Audit Workflow**: Component tests verifying strict mode toggling (`--strict`), contract source paths, and spaces in path arguments.
+- **Workflow Switching**: Component tests ensuring instantaneous tab state changes, workflow description synchronization, dynamic mounting/unmounting of workflow-specific inputs, and seamless clipboard command generation.
