Creating a basic SWAP test for you coin

Add the CAL data for your application

You can find more information about what the CAL is and how it is used in the Crypto Asset List section.

Modify the cal_helper.py file to craft your coin configuration instead of the Boilerplate one.

Do not use the sub_coin_config field for now. You can use it later for tokens if needed; for the time being, the standard configuration is sufficient to get started.

Enable the Exchange tests for your application

The core of the Exchange tests is handled by the ExchangeTestRunner class in the Exchange test client.

Individual tests import and extend the ExchangeTestRunner class to leverage the test framework it provides.

Write a first draft of the Exchange tests for your application, using the Boilerplate tests as an example:

tests/swap/test_boilerplate.py

You can leave the perform_final_tx() function empty for now if you prefer.

You can validate this step by running the swap_ui_only() test for your coin. It should pass, as we coded empty “yes-man” handlers for our tests in the previous section.
