Implement Code Coverage

[readysetagile]

Attempt to implement Code coverage that is automatically run on CI builds

Acceptance Criteria

GIVEN I am a Free Code Camp developer
WHEN I run npm run test on the CLI
THEN the coverage folder will be created
AND all the unit tests will be run
AND I will see the code coverage report

Guidance

• How to Generate a Code Coverage Report with CodeCov and GitHub Actions
• Use the legacy website package.json as an example of how it was working. Making it work like this is fine.
• You might need to create some unit tests!

so simply changing the test line in the scripts section of the package.json file should be enough:

    "test": "react-scripts test --watchAll=false --coverage",

I would like to get our code coverage back in the 'green':

I was able to see a code coverage report from a windows command line.  

C:\repos\cbus-web>set CI=true && npm test -- --env=jsdom --coverage

> [email protected] test
> react-scripts test --coverage --env=jsdom --coverage
