This is a pure function that generates README URL strings based on inputs like username, themes, layouts, and display options. Also included UI tests for the `ReadmeCardUrlSection` component. + +📊 **Coverage:** +* `generateReadmeUrl`: Tested base cases, edge cases (like `username = undefined`), proper serialization of the `hide` parameter (`stars`, `forks`, or both), dynamic inclusions (`streak`, `heatmap`), and custom layout processing. +* `ReadmeCardUrlSection`: Covered UI interactions including state updates (changing checkboxes/selects and ensuring URL updates correctly), clipboard interactions (`navigator.clipboard.writeText`) handling both success and failure cases, and fallback rendering behavior. + +✨ **Result:** +100% statement, branch, function, and line coverage achieved for `src/components/ReadmeCardUrlSection.tsx`. Improved confidence in formatting rules when refactoring layout and display options logic. diff --git a/src/components/__tests__/ReadmeCardUrlSection.test.tsx b/src/components/__tests__/ReadmeCardUrlSection.test.tsx index c0e6177..fe1710d 100644 --- a/src/components/__tests__/ReadmeCardUrlSection.test.tsx +++ b/src/components/__tests__/ReadmeCardUrlSection.test.tsx @@ -1,136 +1,167 @@ // @vitest-environment jsdom -import { afterEach, beforeEach, describe, expect, it, vi } from 'vitest';
