Have already done in the last PR for some. Should i also include library for code coverage ?????

[lavanya-venna]

Can you assign this to me?

[extinctsion]

@Psudopodiya yeah you can. I havent used or built using code coverage pls explain how it works too.

[Psudopodiya]

@extinctsion Sure it simply covers all the situations where the test cases are reaching into your main code for the developers to know which cases they need to add into the test cases.

@Psudopodiya well go ahead. Also, in the next update we are planning to clean the code and redefine the structure.
