Hey @2knal I'm in the middle of working on this issue and if I am not able to solve this one or need any help i will let you know for sure!

@JaDogg I was thinking of adding test coverage for running the tests. Shall I go ahead with it?

[JaDogg]

Do it.

[carpecodeum]

@JaDogg sure!

@JaDogg I propose a few changes but that will require the restructuring of the existing pattern for writing tests. I request you give your views on these! And your inputs and advices too.

1. Use a test client instead of using the development config.
2. make a sample data file for tests.
3. Separating the development and testing config.
