@srijan-27 @Umang01-hash Resolved the issue with the unit tests. Test coverage of current branch : total: (statements) 88.6% Previously ftp module dependencies for running the example were added into gofr.dev module which was not the right approach. So created a separate module for using-add-filestore to isolate the dependencies.

@Umang01-hash Refactored test file to increase the readability of the code. Passing logger into function instead of declaring a global variable. Thanks for the comments!!
