From f2033e45e7de4e3b8165921a14f4a070713939cc Mon Sep 17 00:00:00 2001 From: johndoe6345789 Date: Wed, 21 Jan 2026 04:09:29 +0000 Subject: [PATCH] refactor: enhance Playwright interpreter with comprehensive feature support Implement production-grade PlaywrightTestInterpreter with: Locator Strategies: - test IDs (getByTestId) - ARIA roles (getByRole with name matching) - Labels (getByLabel) - Placeholders (getByPlaceholder) - Alt text (getByAltText) - Titles (getByTitle) - Text content (getByText) - CSS selectors Actions (25+): - Navigation & History: navigate, waitForLoadState, reload, goBack, goForward - Interaction: click, fill, select, hover, focus, blur, type, press - Waits: waitForNavigation, waitForSelector, waitForURL, wait - Input: keyboard shortcuts, mouse buttons, modifiers - Scroll: scrollIntoViewIfNeeded, scroll by coordinates - Screenshots: full page, element, comparison Assertions (20+): - Visibility: toBeVisible, toBeHidden - State: toBeEnabled, toBeDisabled, toBeChecked, toBeEmpty, toBeEditable - Content: toContainText, toHaveText - Attributes: toHaveAttribute, toHaveClass, toHaveValue, toHaveCount - Styling: toHaveCSS (complex style checks) - Visual: toHaveScreenshot - Viewport: toBeInViewport - Page: toHaveURL, toHaveTitle - Custom: custom JavaScript assertions Error Handling: - Detailed error messages with step context - Type-safe step execution - Validation of required fields - Graceful fallbacks Code Quality: - TypeScript types for Page, Locator - Class-based architecture - Private methods with clear responsibilities - Consistent naming conventions - Comprehensive switch statements --- e2e/tests.spec.ts | 374 ++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 330 insertions(+), 44 deletions(-) diff --git
