Global Variables TDD helper updated

June 2, 2014 1-minute read

I’ve update the Globals Adapter in my TDD helper package to allow accessing other global variables beside the superglobals one.
Previously, to access the someVar global variable in code I would have written

// $someVar is a global var

$this->glad = new \tad\adapters\GlobalsAdapter();
$myVar = $this->glad->globals('someVar');

while a discriminating addition in the code now allows for a more streamlined global variable access

// $someVar is a global var

$this->glad = new \tad\adapters\GlobalsAdapter();
$myVar = $this->glad->someVar();

Normal access to someVar global variable would use the global keyword

global $someVar;
$myVar = $someVar;

and while that’s easier to do is also impossible to test in isolation. The Globals adapter, along with the Functions one, was born to satisfy my need for totally testable WordPress plugins and themes.
