infra

integration-test-suite

Project with routines that assist in the execution of integration tests.

Requirements

To use all the basic features of this project, it is necessary to have the docker installed, as well as the docker-compose.

Import

Import this project into your go project using the following statement:

import "github.com/zeroberto/integration-test-suite"

Run the command below to download the lib:

go get github.com/zeroberto/integration-test-suite

Usage

Create a docker-compose file containing your infrastructure services:

# Example of docker-compose.yml
version: "3.8"

services:
  db-test:
    image: postgres
    environment: 
      POSTGRES_USER: test
      POSTGRES_PASSWORD: test
      POSTGRES_DB: test
    volumes:
      - ./resources/sql:/docker-entrypoint-initdb.d
    ports: 
      - 65432:5432
    networks: 
      - test-network
  
networks:
  test-network:
    name: test-network
    driver: bridge

Get your infrastructure up before running your tests. At the end of the tests, your infra must be dropped. Your tests must be performed between these different moments. Below is a complete example of how your test file might look partially:

// Example of test file
import (
  "os"
  "testing"
  "time"

  infra "github.com/zeroberto/integration-test-suite"
)

const (
  host                  string = "localhost"
  serverPort            string = "7777"
  dbType                string = "postgres"
  dataSourceName        string = "postgres://test:test@localhost:65432/test?sslmode=disable"
  dockerComposeFileName string = "docker-compose.yml"
)

func TestFindUserInfo(t *testing.T) {
  // Your test code
}

func TestMain(m *testing.M) {
  setup()
  code := m.Run()
  teardown()
  os.Exit(code)
}

func setup() {
  infra.DownInfra(dockerComposeFileName)
  infra.UpInfra(dockerComposeFileName)
  go initServer()
  validateStructure(dockerComposeFileName)
}

func teardown() {
  infra.DownInfra(dockerComposeFileName)
}

func initServer() {
  // Start your server in a personalized way
}

func validateStructure(dockerComposeFileName string) {
  // Validate that all the conditions of your infra are ok. This is just an example.
  for {
    if infra.CheckPortIsOpen(host, serverPort) && infra.CheckDBConnection(dbType, dataSourceName) == nil {
      return
    }
    time.Sleep(100 * time.Millisecond)
  }
}

Limitations

Some features are only available for Unix-based systems, such as the infra.UpInfraWithEnvs().
