Quality Assurance

Every good programmer and developer should have a living list for Quality Assurance (QA) to ensure that they are signing their name to good work. Below are some tools I've come across in the world to better my skills and to confirm that my work conforms to users' standards.



Websites

Allows you to test your websites in many browsers and devices to make sure everything looks consistent in this modern era where everybody is using something different to view your website in.

GTmetrix gives you insight on how well your site loads and provides actionable recommendations on how to optimise it.

Pingdom's tool tests the load time of a page from a variety of locations around the globe.

This validator checks the markup validity of web documents in HTML, XHTML, SMIL, MathML, etc.

Check cascading style sheets (CSS) for syntax errors.

This tool checks single HTML pages for conformance with accessibility standards to ensure the content can be accessed by everyone.

Advanced SEO analyser tool to give webmasters an in-depth SEO analysis of their websites SEO ranking on a page-by-page basis. This SEO test tool analyses not only your SEO status, but also the website social media ranking, site usability, online reputation, meta tags, and site speed.

Never an issue with having two SEO checks! I personally enjoy this for the keywords cloud it generates and beautiful UI that doesn't scare away most non-tech-y clients like SEO Centro tends to do sometimes.

Not only is it important to have a mobile-friendly site, but you need to make sure that one of the world's biggest search engines knows it too.
