Moto. Mocking AWS

L-ittestjar huwa parti integrali mill-proċess ta 'żvilupp. U kultant l-iżviluppaturi jeħtieġ li jmexxu testijiet lokalment, qabel ma jikkommettu bidliet.
Jekk l-applikazzjoni tuża Servizzi tal-Web tal-Amazon, python librerija moto perfetta għal dan.
Moto. Mocking AWS

Lista kompluta tal-kopertura tar-riżorsi tista 'tara hawn.
Hemm nevew fuq Github Hugo Picado - moto-server. Immaġini lesti, tnedija u użu. L-unika sfumatura hija li wara t-tnedija, le AWS riżorsi għadhom ma nħolqux hemmhekk.

Ukoll, dan huwa faċli biżżejjed biex tirranġa.

Peress li meta tibda għandek bżonn tispeċifika t-tip ta 'servizz (NS varjabbli MOTO_SERVICE), irridu niddeskrivu biss il-ħolqien tar-riżorsa.

Ejja nbiddluha ftit ibda.sh:

Minflok 

moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT

Daħħal:

if [ -f /opt/init/bootstrap.py ]; then
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT & (sleep 5 && echo "Executing bootstrap script." && python /opt/init/bootstrap.py)
else
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT
fi
wait

Il-fajl finali huwa:

ibda.sh

#!/bin/sh

# validate required input
if [ -z "$MOTO_SERVICE" ]; then
  echo "Please define AWS service to run with Moto Server (e.g. s3, ec2, etc)"
  exit 1
fi

# setting defaults for optional input
if [ -z "$MOTO_HOST" ]; then
  MOTO_HOST="0.0.0.0"
fi

if [ -z "$MOTO_PORT" ]; then
  MOTO_PORT="5000"
fi

echo "Starting service $MOTO_SERVICE at $MOTO_HOST:$MOTO_PORT"

if [ -f /opt/init/bootstrap.py ]; then
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT & (sleep 5 && echo "Executing bootstrap script." && python /opt/init/bootstrap.py)
else
  moto_server $MOTO_SERVICE -H $MOTO_HOST -p $MOTO_PORT
fi
# Prevent container from exiting when bootstrap.py finishing
wait

Nibnu immaġni ġdida u nimbottawha fir-reġistru tagħna.

Sussegwentement, ejja nikteb script ta 'inizjalizzazzjoni tar-riżorsi, pereżempju dominju SWF, billi tuża l-librerija biex taħdem ma 'AWS - boto3:

bootstrap_swf.py

import boto3
from botocore.exceptions import ClientError
import os

os.environ["AWS_ACCESS_KEY_ID"] = "fake"
os.environ["AWS_SECRET_ACCESS_KEY"] = "fake"

client = boto3.client('swf', region_name='us-west-2', endpoint_url='http://localhost:5000')

try:
    client.register_domain(
        name='test-swf-mock-domain',
        description="Test SWF domain",
        workflowExecutionRetentionPeriodInDays="10"
    )
except ClientError as e:
    print "Domain already exists: ", e.response.get("Error", {}).get("Code")

response = client.list_domains(
    registrationStatus='REGISTERED',
    maximumPageSize=123,
    reverseOrder=True|False
)

print 'Ready'

Il-loġika hija din:

  • Meta nibdew, inarmaw l-iskrittura tagħna /opt/init/bootstrap.py.
  • Jekk il-fajl huwa mmuntat, se jiġi eżegwit.
  • Jekk ma jkunx hemm fajl, il-moto-server vojt se jibda sempliċement.

U, tista' tiċċaqlaq riżors kollu billi tniedi kontenitur wieħed:

docker run --name swf -d 
    -e MOTO_SERVICE=swf 
    -e MOTO_HOST=0.0.0.0 
    -e MOTO_PORT=5000 
    -p 5001:5000 
    -v /tmp/bootstrap_swf.py:/opt/init/bootstrap.py 
    -i awesome-repo.com/moto-server:latest

Ejja nippruvawha b'mod interattiv:

Moto. Mocking AWS

Jaħdem!

Allura nistgħu nagħmlu docker-compose.yml, li se jiffranka l-ħin fil-bidliet fl-ittestjar:

docker-compose.yml

version: '3'
services:
  s3:
    image: picadoh/motocker
    environment:
      - MOTO_SERVICE=s3
      - MOTO_HOST=10.0.1.2
    ports:
      - "5002:5000"
    networks:
      motonet:
        ipv4_address: 10.0.1.2
    volumes:
      - /tmp/bootstrap_s3.py:/opt/init/bootstrap.py
  swf:
    image: picadoh/motocker
    environment:
      - MOTO_SERVICE=swf
      - MOTO_HOST=10.0.1.3
    ports:
      - "5001:5000"
    networks:
      motonet:
        ipv4_address: 10.0.1.3
    volumes:
      - /tmp/bootstrap_swf.py:/opt/init/bootstrap.py
  ec2:
    image: picadoh/motocker
    environment:
      - MOTO_SERVICE=ec2
      - MOTO_HOST=10.0.1.4
    ports:
      - "5003:5000"
    networks:
      motonet:
        ipv4_address: 10.0.1.4
    volumes:
      - /tmp/bootstrap_ec2.py:/opt/init/bootstrap.py
networks:                             
  motonet:                          
    driver: bridge                
    ipam:                         
      config:                       
        - subnet: 10.0.0.0/16

Fil-fatt, dan l-approċċ jista 'jintuża mhux biss fuq laptop ta' żviluppatur. Testijiet preliminari b'mocks wara l-assemblaġġ se jgħinu biex teħles minn problemi possibbli meta taħdem fuq ambjenti dev*.
