6. Test Your Plugins Thoroughly
   The last part of any good software development cycle is polishing, prepping and testing the product for release. Here are my suggestions for when you are getting ready to deploy the initial release of your plugin, or are preparing a version release:

Debug your plugin with wp_debug enabled until everything is resolved.
Test the plugin on a fresh WordPress install.
Test the plugin using multiple WordPress themes.
Consider testing the plugin on old WordPress versions and PHP versions that you suspect might affect the functionality of the plugin.
Analyze and test your plugin with browser developer tools (DevTools for Chrome, Firebug for Firefox, etc.).
Compress all front-end files (HTML, CSS, and images). Include non-minified versions of your stylesheets and HTML files so that the plugin user can perform custom modifications.
Write good documentation. Documenter can be helpful with this process.
