Create test file and benchmarking for pallet-accounting

[chrisdcosta]

The pallet-accounting has been enhanced with a new set of apis, currently on the opening-balances-adjustments branch.

It should be noted that this is a first version of these apis, and that further enhancements may be made in time.

Tests:

Build comprehensive test cases for:

• pub fn set_accounting_ref_date()

• pub fn set_opening_balance()

• pub fn adjustment()

Set the mock.rs file with the appropriate parameters, and build the tests in test.rs.

Uncomment these line in lib.rs

//pub mod benchmarking;
//pub mod mock;
//pub mod tests;

Note

The tests should cover scenarios that would cause the extrinsic to fail, as well as those that would allow the extrinsic to succeed. The most complex of the the functions is the adjustments, but it also incorporates checks that are used in the

Benchmarking:

Build the initial benchmarking for all three functions and change the lines #[pallet::weight(0/*TODO*/)] to handle the weights properly.

• pub fn set_accounting_ref_date()

• pub fn set_opening_balance()

• pub fn adjustment()

There may be an additional change to the runtime/src/totem.rs file for the weight parameters.
