Adam delivered Playwright Component Testing support for passing function props in portable stories within the storybookjs/storybook repository. He updated the WrappedStoryRef structure to include a props field, implementing logic to exclude non-serializable props from browser evaluation, which addressed the challenge of handling function props in test environments. Using TypeScript and Playwright, Adam added an end-to-end test, Button.playwright.tsx, to demonstrate that an onClick handler prop could be passed and executed as expected. This work improved test coverage and reproducibility for portable stories, enabling more realistic user-interaction scenarios and enhancing the overall robustness of component testing workflows.
