AND YOU WRITE YOUR PLUGINBut creating your plugin isn’t all about the code. It also mean maintenance of it.

SETTING UP YOUR UNIT TESTS

wp  scaffold  plugin-­‐tests  

• phpunit.xml is the configuration file for PHPUnit• .travis.yml is the configuration file for

Travis CI• tests/bootstrap.php is the file that makes

the current plugin active when running the test suite• tests/test-sample.php is a sample file

containing the actual tests11

SETTING UP YOUR UNIT TESTS

My  basic  tests  are:  

• test_tested_up_to• test_stable_tag• test_package_json

AUTOMATION OF YOUR TASKS

YOUR NORMALLYTASKS

• Minify CSS/JS• Compress CSS/JS/Images• Concatenate CSS/JS• Validate JS• Create new pot file• Download translations• Unit test• Deploy

GRUNT

•Running  tasks  by  using  CLI  

•Easy  to  use,  harder  to  configure  

•Extendable  with  your  own  plugins  

•Uses  npm  for  plugin  management  

THE JAVASCRIPT TASK RUNNER

http://gruntjs.com

THE BASIC SETUP

A typical setup will involve adding two files to your project: package.json and the Gruntfile

• package.jsonThis file is used by npm to store metadata for projects published as npm modules. You will list grunt and the Grunt plugins your project needs as devDependencies in this file.• Gruntfile

Is used to configure or define tasks and load Grunt plugins.
