# or 
make run
# or
make run args="-port 3000 -filepath auction.dump"
# or
./start -port 3000 -filepath auction.dump

Test

For run all tests you can use

For run tests with args you can use some like this

make test args="-v db/*.go -run TestDb"

or for specify benchmark tests

make test args="./... -bench Db"

Test while run

first run the server

make run

so seed this server

curl -X POST -s localhost:3000/bid --data '{"item_id": "23", "price": 1.94, "client_id": "1"}'
curl -X POST -s localhost:3000/bid --data '{"item_id": "23", "price": 1.94, "client_id": "2"}'
curl -X POST -s localhost:3000/bid --data '{"item_id": "2", "price": 1.94, "client_id": "2"}'
curl -X POST -s localhost:3000/bid --data '{"item_id": "2", "price": 1.98, "client_id": "2"}'
curl -X POST -s localhost:3000/bid --data '{"item_id": "23", "price": 1.93, "client_id": "3"}'
curl -X POST -s localhost:3000/bid --data '{"item_id": "2", "price": 3.10, "client_id": "3"}'

then see the stats

curl -X GET -s localhost:3000/stats | jq "."
