GoLang playground building a CLI to calculate tax over stock trading

The CLI was built on the premise of having a input of arrays of orders as of the following pattern json { operation: buy/sell , quantity: integer, unit-cost: float }

with Go 1.16 installed, you can simply build the program and run it passing -input=[] flag containing the orders

To build the program with taxcalculator name:

go build -o taxcalculator .

go test ./utils

Since all tests were written for the utils package and the main program solely handles inputs and calls utils functions, we call the tests from utils

After building the program, simply run

./taxcalculator -input=[] with the desired Input of orders

Example:

./taxcalculator -input='[{"operation":"buy", "unit-cost":10.00, "quantity": 10000}]'

If you wish to use Docker just follow the next steps

docker build -t taxcalculator .

To run unit tests on Docker, simply build the Dockerfile.test image and then run it, as follows:

docker build -t taxcalc-test -f Dockerfile.test .

docker run taxcalc-test

pattern: docker run taxcalculator -input='[]'

usage example: docker run taxcalculator -input='[{"operation":"buy", "unit-cost":10.00, "quantity": 10000}]'
