CONTAINERS TO RESCUE
WHAT ?
CONTAINERS
AN APPLICATION, PLUS ALL ITS DEPENDENCIES, LIBRARIES AND OTHER BINARIES, AND CONFIGURATION FILES NEEDED TO RUN IT, BUNDLED INTO ONE PACKAGE.
WHAT ARE CONTAINERS?
AN ENTIRE ISOLATED PORTABLE RUNTIME ENVIRONMENT

HOW?
CONTAINERISE YOUR STACK
1.INSTALL DOCKER (ONLY)
docker for mac / windows docker toolbox docker engine for linux
2.WRITE DOCKERFILE▸ configuration file with build instructions for
Docker images
3.WRITE COMPOSE ▸ Compose is a tool for defining and running
multi-container Docker applications
SIMPLE VOTING APP : APP UNDER TEST▸ Simple Real Time voting app
▸ Runs with Docker Compose and multiple containers in network
VOTING APP : COMPONENTS
Deliver below tests as container to test Voting app
1.API 2.Web 3.Web with Selenium Grid
