 **Helpful Testing Process**
 
-One technique that can helpful when writing tests, is to reference the coverage report for the file/function/feature you're testing. To do this, run `yarn test:dev` from your terminal. This will generate a coverage report for the project in the `coverage` directory. To view the report, open the file `coverage/lcov-report/index.html`.
