testify-tutorial

This repository contains the code for my testify tutorial youtube video series. It shows how to use testify together with mockery to build awesome golang tests.

Description

The tests are written for the calculations package and test the PriceIncreaseCalculator functionality which depends on PriceProvider interface.

Prepare Postgres in Docker

If you want to run integration tests you need to have a running postgres instance. The constants that are being used are the default ones from dockerhub

const (
	dbHost     = "localhost"
	dbPort     = 5432
	dbUser     = "postgres"
	dbPassword = "mysecretpassword"
	dbName     = "postgres"
)

All you need to do is execute the following command and you should be good to go

docker run --name pg-testify -e POSTGRES_PASSWORD=mysecretpassword -p 5432:5432 postgres

Running the tests

# run all tests
go test ./calculations

# only run unit tests
go test ./calculations -run UnitTestSuite -v

# only run integration tests
# running postgres instance required
go test ./calculations -run IntTestSuite -v
