Unit and Integration Tests Infrastructure

[zainfathoni]

Overview

Thanks to our fellow contributors, this project grows fast in the past few days.
It's time to introduce a proper infrastructure for unit and integration tests.

This epic is blocking #294.

References

You can refer to this project as an example.

Current Tasks

• Install jest and testing-library family of libraries #179
  • Jest as a test runner
  • Testing Library family of libraries as React test renderers
  • kcd-scripts for an easy testing scripts usage
• Start writing tests for ReportButton component as an example #180
• Use the test script in the lint-staged script to ensure all tests related to the changed files are successful prior to the git commit operation #181
• Use the test script in the .github/workflows/test.yml file to run the tests for every Pull Request made #182

@zainfathoni We should potentially also include Typescript + ESLint in the CI to catch any type/lint errors as well alongside unit tests.

Shall we create another epic for the .github/workflows/test.yml file to contain everything needs to be done on the CI validation step @resir014? We can track some of these issues in that epic as well.

UPDATE:
The epic has been created on #186.

@zainfathoni I think we should expedite this issue.

Since we're getting a lot more tasks which need unit/integration tests available (e.g. #197, #294) we should make this high-priority and shouldn't delay any further in implementing unit/integration tests.

Agreed.
I'll work on it tonight.
