Add tests for comments counter

[NitBravoA92]

Hi Partner @PabloBona 🤵

I have implemented the last functionality necessary to complete the project and I'd like you to review it before I can integrate this code into the dev branch:

Updates Details 📜

✅ I have created a new test file called commentsCounter.test.js. In this file, I have created three test cases to check the quality and proper functioning of the commentsCounter() function, which displays the number of comments listed in the popup. These test cases are:

• Test case 1: When there are no comments listed in the popup, the counter should be at zero (0). This test passed successfully.

• Test case 2: When there are three comments listed in the popup, the number three (3) should appear in the counter. This test passed successfully.

• Test case 3: When there are ten comments listed in the popup, the number ten (10) should appear in the counter. This test passed successfully.

If you feel there are bugs, major issues, or major changes that need to be made ♻️, please contact me 📞 via Zoom or Slack call to discuss them.
