How to run the test application

1. yarn install the dependencies.
2. yarn start to start the front-end.
3. yarn run start-server to start the back-end.

Task directions

• Complete at least 4 types of tests below (unit, integration, component and E2E tests).
• The goal is augment the project with tests to ensure correct operation in the future.
• You can use any tool to achieve this. Cypress is a preferred framework for testing, but you can use a framework of your choosing as well (it does not affect scoring).
• You can change the source code to accommodate it for tests, as long as you are not breaking functionality.

Ideas for tests

You can rely on your own experience as to what types of tests are added, but here are a couple ideas to get started:

• Unit tests
• Integration tests
• Component tests (preferable with Jest. For better understanding https://medium.com/opendoor-labs/testing-react-components-with-jest-a7e8e4d312d8)
• E2E tests
• Test coverage instrumentation
• Visual regression tests
• Type safety

Deliverables

• You need to return all project files with the added tests.
• In case you find a bug(s) feel free to create a report.

What I've done

• set css-attributes in frontend for tests (example: marker="add-pizza-btn")
• created page objects for e2e-tests
• created e2e-ui tests both checking the display of elements and the execution of cases
• implemented the ability to run tests from the console specifying the test host (a preparatory step for running on CI)
• wrote the first unit test for the handler (appFetch.test.js) - the test is launched via the play button in IDE

What didn't get done

• did not decide how best to automatically raise the environment before running tests locally, there is an idea to run it with a script, but there are disadvantages, you need to study the documentation
• deploying test frontend and backend in docker and running tests in a container
• did not provide output of test coverage and testing reports
• did not write integration, acceptance, visual regresssion tests && type safety

Run tests

Run with test-host (e2e-tests) & api-host (api-tests) cypress run --env host=http://localhost:3000 api-host=http://localhost:3001
