I have:

• Manually tested my work with and without JavaScript
• Tested any Views or partials created or changed with Wave Chrome plugin and addressed any valid accessibility issues
• Updated/added documentation in Confluence and/or GitHub Readme. List of documentation links added/changed:

• Scanned over my pull request in GitHub and addressed any warnings from the GitHub Build and Test checks.
