Jest test coverage

[cjcenizal]

We need more comprehensive test coverage for components which have a variety of props and/or possible prop values, or internal state and complex behavior. The goal is to establish snapshots to cover the various classes which can be applied to a component, and to verify correct behavior when the user is interacting with a component. These tests should follow our testing guidelines.

A few examples of the components which need coverage are:

• Accordion (expanding/collapsing behavior) Add test coverage for EuiAccordion. #183
• Avatar (multiple props) Add test coverage for EuiAvatar. #184
• Badge (multiple props) Add test coverage for EuiBadge. #185
• BottomBar (paddingSize prop, which is missing from propTypes) Add test coverage for EuiBottomBar. #186
• Button (LOTS of props) Add test coverage for EuiButton, EuiButtonIcon, and EuiButtonEmpty #187
• CallOut (multiple props) Add test coverage for EuiCallOut. #188
• DescriptionList (multiple props) Add test coverage for EuiDescriptionList #189
• Expression (complex behavior and mouse interaction -- note that this component also needs refactoring per Refactor EuiExpression to use EuiOutsideClick #176) Update EuiExpression with latest changes from KUI #190
• Flex (multiple props) Flex tests #192
• Form (lots of components with multiple props) Form tests - Phase 1 #196, Form tests - Phase 2 #207
• Header (lots of child components, but fairly simple)
• Link (multiple props)
• Loading (multiple props)
• Modal (multiple props)
• OutsideClickDetector (complex behavior)
• Pagination (complex behavior)
• Panel (multiple props)
• Progress (multiple props)
• Tabs (complex behavior)
• Text (multiple props)
• Title (multiple props)
• Toast (multiple props and complex behavior) toast component jest tests #215
