Deployment/Testing Strategy:
Multiple deployment/testing strategies have been added for easy execution of the test scripts. Below are the details regarding these strategies.

1. Using shell file

• The shell file can be used to run all services and automation suite using a single command.

./cypress-run.sh

2. Using Makefile

• A makefile has been included to perform some of the basic tasks required.

• Build services:

make docker-build

• Run services:

make docker-up

• Run tests headlessly:

make test

• Run tests using a test runner:

make test-gui

3. Using Cypress Test Runner

• Test runner can be built locally and used to test the automated scripts. For this test runner should be opened. In order to open the test run, go inside the e2e folder and then use the command below:

npx cypress open
