The test suite now covers: + - Form rendering (input and submit button). + - State updates when typing in the input. + - Form submission logic and conditional disabling of the search button for empty inputs. + - Ensuring whitespace-only submissions are prevented. + - Verification that the username is trimmed and URI encoded properly before calling `router.push`. + - Simulating the React `useTransition` loading state where the button becomes disabled and displays "Loading...". +✨ **Result:** Enhanced test coverage and reliability for user search workflows. Improved testing confidence by mocking `next/navigation` and React hooks effectively. diff --git a/src/components/SearchForm.test.tsx b/src/components/SearchForm.test.tsx new file mode 100644 index 0000000..134af4d --- /dev/null +++ b/src/components/SearchForm.test.tsx @@ -0,0 +1,115 @@ +/** + * @vitest-environment jsdom + */ +import { render, screen, fireEvent, waitFor } from "@testing-library/react";
