Adding Testing Framework and tool

Hi everyone,
For this project, I opted for the Mocha testing framework along with the assert library. Mocha is a versatile and feature-rich testing framework for Node.js, offering a simple interface, asynchronous support, and a variety of reporters. The assert library provides basic assertion functions to perform tests within Mocha.

☕MOCHA- Testing Framework
Mocha is a widely-used testing framework for JavaScript, particularly in Node.js environments. It provides a flexible and user-friendly structure for testing by supporting various testing styles like BDD (Behavior-Driven Development), TDD (Test-Driven Development), and much more. Mocha excels in asynchronous testing and offers an array of plugins and custom reporters.

Assert Library
This library is a core in Node.js module, providing functions that aid in writing test assertions. It includes methods for validating different types of data and checking the expected results against actual outcomes.

Setting Mocha in the project:-

1. Installation: Installing Mocha and assert in the project via npm:
   npm install mocha assert --save-dev

2. Project Structure:

• Test File: A test file named test.js was created to house the test suites and cases.
• Mocha Configuration: An npm script was added in the package.json to run the tests using Mocha.

1. Writing Test Cases:

• The test file (test.js) was set up with test suites to check the functionality of specific functions within the project.
• Each test suite contained multiple test cases covering various scenarios and edge cases.

1. To run the testing file:

• You can edit the text file present in src folder named "till-1.txt" or by adding new text file and updating the file path in the "test.js" file.
• After completing above step run the below command in terminal for the desired output which will be placed in output directory.

npm test

Talking about Bugs and errors
The tests uncovered a few interesting edge cases, notably regarding file paths and the handling of file existence checks. These tests provided a robust means to detect potential issues in the code logic. I solved this error by the help of assert library which provided clear and detailed message where the testing file was getting failed.

CONCLUSION:
This experience was my first deep dive into testing using Mocha and the assert library. It shed light on the significance of testing in ensuring code reliability and quality. The process solidified the understanding that comprehensive testing is invaluable in a project's development phase.

The practice not only ensures code stability but also enhances my understanding of the codebase and evaluating project more carefully. The value of testing is paramount, and I believed it as an indispensable part of the development process in projects.

Overall, this journey into testing was enlightening and looking forward to implement more testing other functions.🍵
