UNIX-like environment in which to build it.

or newer.

Testing

$3

Components’ unit tests live in the tests/components. The tests are organized following the same
directory structure used to organize components.

- yarn test:unit runs all unit tests.

- yarn test:unit:watch runs all unit tests in watch mode.

- yarn test:unit:debug runs all unit tests and allow to attach a debugger to the test runner process.

- yarn jest [name_pattern] runs spec files that match the specified name pattern.

#### Examples

- yarn jest datepicker will match all spec files with a name that contains the word _datepicker_.

- yarn jest datepicker -t "when draw event is emitted" goes a step further and only runs the test
with a description that matches the argument passed to the t flag.

Duo UI uses visual snapshot tests to prevent introducing regressions with CSS and
layout changes on components. Read more on this in the visual testing documentation.
