Unit
Unit tests use the Mochamocha test framework with Chaichai assertions. To run the tests, execute the following command in the top-level application directory:$ make testAll new feature development should have corresponding unit tests to validate correct functionality.
Test Coverage
This repository uses Istanbulistanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:$ make test-covIstanbul creates a
./reports/coverage directory. To access an HTML version of the report,$ make view-cov
