First off: After I mentioned last week that I needed a POP mail account to test with, several folks with their own mail servers offered their help. I’m set up with something now. Thanks to all who reached out!
The past week has been all about testing, with the goal of getting good unit and/or integration tests written for the Post By Email plugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party before I start adding features to it. This is entirely new territory for me, though I’ve done some TDD in Ruby in the past. So far, I’ve learned how the tests work on Core Core is the set of software required to run WordPress. The Core Development Team builds WordPress., and gotten a whole mess of things installed and running (wp-cli WP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is http://wp-cli.org/ https://make.wordpress.org/cli/, Pear, PHPUnit, etc.). I followed this guide to set up the basic test structure for the plugin. I was hoping to have some actual tests done for this week’s update, but it took a bit longer than expected to get the framework set up, so I don’t have anything ready for primetime yet.
So, this week’s question: What are some plugins that have really good tests? I’m seeking examples of what to do (or not to do!). I’m especially curious to see tests of Settings API An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. stuff and install/activation functions.
Side note: I really need to clean up my development setup for testing against multiple WordPress versions. I have several versions installed already, but they’re pretty haphazard (with different databases, inconsistent directory names, etc.). I found this very good post about a development setup with multiple WP versions. For those of you who support plugins or themes on multiple versions — any tips? Is your setup similar to that post?
