+# Unit Testing
+
+We use unit testing to ensure that individual components of the codebase work as we expect them to.
+
+We have a collection of tests under the `test/unit` folder that run in the browser and a collection of tests under `test/node` that run in node.
+
+## Running All the Unit Tests
+
+In the repo root, use the following command in your terminal
+
+```shell
+npm test
+```
+
+### Running One Suite
+
+To run a single test or group of tests, append `.only` on a `suite` or `test` in your `.js` file and run the tests using the above command.
+
+**Be careful you don't commit `.only` though!** (We always want Travis CI to run _all_ the unit tests.)
+
+#### An Example
+
+To only run the "p5.ColorConversion" suite of tests, you would change the first line of `test/unit/color/color_conversion.js` to read:
+
+```js
+suite.only('color/p5.ColorConversion', function() {
+```
+
+Now when you use `npm test`, only tests within that `function()` will be run.
+
+## Frameworks
+
+We use [mocha](https://mochajs.org) for structuring and running the unit tests
+
+We use [chai's `assert` (and `expect`)](https://www.chaijs.com/api/assert/) to write individual statements about how code should behave

+## Adding Unit Tests
+
+If you want to add more unit tests, look and see if there's already a test file for the component you want to add tests for. Generally, tests for a given file in `src/` are at the same path under `test/unit`. (For example the tests for `src/color/p5.Color.js` are in `test/unit/color/p5.Color.js`.)
+
+If you can't find one, that's probably because there aren't any tests for that file (yet 😉), so create a new file according to the conventions above. If the module you're testing requires a browser to work, you'll want to put it in `test/unit`, but if it doesn't, you might want to add it under `test/node`. **When in doubt, default to adding a browser test in `test/unit`! (It's pretty easy to move a later if we need to.)**
+
+If you have to add a test file for a module to `test/unit`, then you'll also need to the module under test to the `spec` array in `test/unit/spec.js`. This will make sure the necessary modules are loaded for your test to run.
