 ## Unit tests for a package
 
-Currently there are two patterns used to test packages, one using Mocha and one using Jest. These patterns emerged out of convention and we'd like to make them more similar to each other in the near future.
+Currently there is only one tool being used in order to test packages which is Jest. Below we will explain how it should be done.
 
-### 1. Mocha
-Today a package can follow the pattern of having a `__tests__` directory in each source code directory of a package which contains the tests for that module. These are usually run by Mocha.
-
-If a package's tests should be run with Mocha, you'll have to opt-in to run them by appending the package's test file pattern(s) to Kibana's `src/dev/mocha/run_mocha_cli.js` file. These will then be run by the unit test runner.
-
-* `yarn test` or `yarn grunt test` runs all unit tests.
-* `node scripts/mocha` runs all Mocha tests.
-
-### 2. Jest
-A package can also follow the pattern of having `.test.js` files as siblings of the source code files, and these run by Jest.
+### Jest
+A package should follow the pattern of having `.test.js` files as siblings of the source code files, and these run by Jest.
 
 A package using the `.test.js` naming convention will have those tests automatically picked up by Jest and run by the unit test runner, currently mapped to the Kibana `test` script in the root `package.json`.
 
 * `yarn test` or `yarn grunt test` runs all unit tests.
 * `yarn jest` runs all Jest tests in Kibana.
 
+In order for the plugin or package to use Jest, a jest.config.js file must be present in it's root. However, there are safeguards for this in CI should a test file be added without a corresponding config file.
+
 ----
 Each package can also specify its own `test` script in the package's `package.json`, for cases where you'd prefer to run the tests from the local package directory.
