@NadeemYaseen, this is as we discussed. Please connect with me once you are in your working hours.

Please move these tests to the following folder.
https://github.com/os-fpga/rapid_power_estimator/tree/main/tests/e2e

[shivaahir158]

@ravikiranchollangi , this 'test' folder is for the backend tests, frontend tests are 'test' folder under 'src'.

Do you still want me to move the tests under the 'playwright_e2e' to the test folder where backend tests are located? Let me know so I shall do the needful.
