Unit Testing

What is Unit Testing… and why?

Unit tests are intended to test a single piece of functionality, while mocking away all external dependencies. The goal of a unit test is to know that a particular function or piece of code works exactly as expected under all of the possible code paths. Unit tests should not include any external dependencies.

Running Unit Tests

The complete suite of unit tests can be run locally using command npm test from the top directory.

Jest frontend testing

Unit testing for the vue application td.vue is done using jest, and lives in the td.vue/tests/unit directory.

If you’d prefer to work in a more TDD fashion, you can have the tests run continuously by navigating to the td.vue directory and running npm run test:unit -- --watch

Mocha backend testing

Unit testing for the server application td.server is done using Mocha, with a little help from our friends Sinon.JS and chai. To run the tests locally navigate to the td.server directory and run: npm run test:unit

Code Coverage

When you run unit tests for both the front-end and back-end application, you will be presented with a code coverage report. There will be an HTML report generated as well that you can view to dig deeper into what sections may be missing coverage.

We hope to keep the code coverage as high as possible. If you need help writing or updating tests, please just ask!
