Run the tests

# make test 

clj -M:test

Running tests in #{"test"}

Code Walkthrough

Starts with the main entrypoint braintree/-main. We read input from either filepath or piped stdin. Then we process input line by line, one at a time. For each line/command, store and updates {<name> {card: <card>, balance: <balance>, ...}, ...}. Finally, print out the summary.

The test cases braintree/main-test exercises the flows with reasonable input assumptions documented.

Happy to walkthrough the code!
