 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 `tasks/config/simplemocha.js` file. These will then be run by the unit test runner.
