Lesson Qa Checklist

Pre-launch QA Diligence

Prior to the launch of web sites both big and small, there are several techniques and best practices to help ensure the delivery of a quality product that is performant and bug free. Often times addressed toward the end of a project, one of the most commonly used terms to describe this step of the process is quality assurance, or QA.

Quality assurance (QA) is a way of preventing mistakes and defects in manufactured products and avoiding problems when delivering solutions or services to customers

Bug Tracking

• Track and Prioritize your Bugs and Tasks
  • Online tools: Google Spreadsheets (Example QA Bug Tracking Sheet), Trello Boards (Example Trello Bug Tracking Board), Github Issues, etc.
• Validate your code
  • Validate HTML
  • Validate CSS
  • Validate Accessibility (Section 508 compliance)
    • Provide "equivalent" experience to all users. For example, make sure all img alt tags are appropriate.
    • Check out online resources, such as: The W3C Web Accessibility Initiative (WAI) and their list of resources, the A11Y Project, ARIA, etc.

Performance Enhancements

Techniques to improve the speed of your site

• Test your site at web.dev and Google Page Speed Insights
• Conduct a site audit for K size of all assets
• Optimize all media (e.g. images, videos, etc). Example: manually adjust via Photoshop's Save for the web (legacy). Recommended Image Formats:
  • jpg (for images/raster photos with lots of color)
  • gif (for images/illustration with under 256 colors)
  • png-24 (for images that require alpha transparency

• Minify all local dependencies (html, css, and js)
• Considerations:
  • Consider using a CDN
  • Consider using a critical css file
  • Consider file compression (e.g. gzip)

Due Diligence

Style guides, code clean-up, and more...

• Refactor all code by removing any redundant or unnecessary code.
  • Remove unused markup (html)
  • Remove unused styling (css)
  • Concatenate your Javascript into one js file
• Consider creating in-house style guidelines & documentation (for internal developer use and/or client use).
