    • `framework` (enum, required): Testing framework (`jest` | `cypress`).
    • `type` (enum, required): Type of test (`unit` | `component` | `e2e`).
    • `config` (record, optional): Configuration object for test execution.
• testReactComponent: Runs component tests specifically for React components.
  • Parameters:
    • `componentCode` (string, required): The source code of the React component.
    • `testCode` (string, optional): Test code for the component (auto-generated if not provided).
    • `framework` (enum, optional): Testing framework (`jest` | `cypress`, default: `jest`).
    • `props` (record, optional): Props to pass to the component during testing.
    • `autoGenerateTest` (boolean, optional): Automatically generate test code if not provided (default: `true`).

Resources

• templates: Provides test templates.
