Unit test case coverage lacking

[samarpan-b]

Describe the bug Unit test case coverage missing and not up to the mark

Expected behavior We should have at least 75% unit test case coverage in all micro services

Screenshots

Additional context We can divide this into separate tasks for each microservice and then implement the same.
