-`yarn run test:browserstack` to run the kv acceptance tests in Browserstack
#### Automated Cross-Browser Testing
Vault uses [Browserstack Automate](https://automate.browserstack.com/) to run all the kv acceptance tests on various browsers. You can view the list of browsers we test by viewing `testem.browserstack.js`.
##### Running Browserstack Locally
To run the Browserstack tests locally you will need to add your `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` to your environment. Then run `yarn run test:browserstack`. You can view the currently running tests at `localhost:7357` or log in to [Browserstack Automate](https://automate.browserstack.com/) to view a previous build.
To run the tests locally in a browser other than IE11, swap out `launch_in_ci: ['BS_IE_11']` inside `testem.browserstack.js`.

### Writing Stories
Each component in `vault/ui/app/components` should have a corresponding `[component-name].stories.js` and `[component-name].md` files within `vault/ui/stories`.
#### Adding a new story
1. Make sure the component is well-documented using [jsdoc](http://usejsdoc.org/tags-exports.html). This documentation should at minimum include the module name, an example of usage, and the params passed into the handlebars template. For example, here is how we document the ToggleButton Component:
````js
/**
*@module ToggleButton
*`ToggleButton` components are used to expand and collapse content with a toggle.
*@param toggleAttr=null {String} - The attribute upon which to toggle.
*@param attrTarget=null {Object} - The target upon which the event handler should be added.
*@param [openLabel=Hide options] {String} - The message to display when the toggle is open. //optional params are denoted by square brackets
*@param [closedLabel=More options] {String} - The message to display when the toggle is closed.
*/
````
Note that placing a param inside brackets (e.g. `[closedLabel=More options]` indicates it is optional and has a default value of `'More options'`.)
2. Generate a new story with `ember generate story [name-of-component]`
3. Inside the newly generated `stories` file, add at least one example of the component. If the component should be interactive, enable the [Storybook Knobs addon](https://github.com/storybooks/storybook/tree/master/addons/knobs).
4. Generate the `notes` file for the component with `yarn gen-story-md [name-of-component]` (e.g. `yarn gen-md alert-banner`). This will generate markdown documentation of the component and place it at `vault/ui/stories/[name-of-component].md`. If your component is a template-only component, you will need to manually create the markdown file.
See the [Storybook Docs](https://storybook.js.org/docs/basics/introduction/) for more information on writing stories.
### Code Generators
It is important to add all new components into Storybook and to keep the story and notes files up to date. To ease the process of creating and updating stories please use the code generators using the [commands listed above](#storybook-commands-at-a-glance).
