Implementing Testing for Web Application using Jest and Playwright

**Description**

Our web application currently lacks any testing infrastructure, which can lead to potential issues and regressions in the codebase. To ensure the stability and reliability of our application, we aim to implement comprehensive testing using Jest and Playwright. This will include both unit testing for individual components and modules, as well as end-to-end (e2e) testing to simulate user interactions and validate the overall functionality.

**Objective**

The objective of this issue is to introduce testing capabilities to our web application by utilizing the Jest testing framework for unit testing and Playwright for end-to-end testing.

**Tasks**

1. **Setup:** We will begin by setting up the testing environment in our project. That includes installing Jest and Playwright and any other required packages.

2. **Unit Testing:** With the testing environment in place, we will write unit tests for individual components and modules of our application. Unit tests will ensure that each component behaves as expected in isolation and helps in catching bugs early in the development process.

3. **End-to-End Testing:** In addition to unit tests, we will implement end-to-end tests using Playwright to simulate real user interactions and test the application's functionality as a whole. End-to-end tests will validate critical user flows and identify potential issues in the user experience.

4. **Code Coverage:** We will aim for a high code coverage percentage to ensure that the majority of our codebase is covered by tests. Code coverage reports will be generated to assess the effectiveness of our test suite.

5. **Integration with CI/CD:** We will integrate the test suite with our continuous integration and continuous deployment (CI/CD) pipeline to automatically run tests on every code commit.

6. **Documentation:** As we implement testing, we will also update the project documentation to include guidelines for writing and running tests, making it easier for future contributors to maintain and expand the test suite.

**Expected Outcome**

By implementing testing using Jest and Playwright, we expect to achieve the following outcomes:

- Increased stability and reliability of our web application through early bug detection.
- Improved code quality and maintainability with a comprehensive test suite.
- Enhanced confidence in making changes to the codebase without introducing regressions.
- Integration of testing into our CI/CD pipeline for automated testing on each code change.

**Contributions**

If you have experience with Jest, Playwright, or web application testing in general, we encourage you to collaborate with us on this issue to ensure the quality and robustness of our application.
