Migrate tests from using Enzyme to use React Testing Library

                        Refactor tests using react-testing-library to emphasize behavior checks rather than implementation specifics. 
                        Retain the original test count and descriptions.
                        Disregard the initial test content. Comprehend the test's intent and use {{ htmlStr }} for precise browser rendering when forming the test.
                        Refer to the component's source code {{ imports }} while crafting the tests.
