FS-49: Adding cypress testing

Description

• Adds cypress package to devDependencies
• Adds setup configuration for cypress
• Updates scripts in package.json to run cypress
• Adds cypress.json configuration file
• Updates README.md
• Adds some basic test coverage of application
  • Tests if key markups are rendered on the DOM

Testing instruction

• Pull down code
• Remove node_modules directory
• Run yarn install && yarn start
• Run yarn cypress to start Cypress electron binary. This will open another app to run test.

• Click on "Run all specs", this will open a Chrome to run all the steps.
• Verify tests are running and all tests pass.

Known issues

• Verify demo box is running for Solr index to be queried. If not, the test will time out and result in a timeout/error message.

Open questions

• Should there be more automation in this approach? Would running yarn cypress to run tests be missed for future developers?

• Cypress requires a cypress.json file to be added with a defined baseUrl with the value localhost:3000. I can see if there are other ports it might cause some confusion. Would we need to look into more abstract solution to handle cases where a developer is on port 3001?

This default test only passes if the autocomplete is disabled. I fixed that by changing the selector in the test.

As to the questions:

1. I think running yarn cypress is fine. Just document it.
2. Port 3000 is fine. Again, just document that setting.

Your changes looks good. I have also updated the readme file with the items about ports and command to run tests.
