The Wonderful World of Callbacks
Anybody that has read any of my previous blog posts or looked at my code samples before should know that I’m a big fan of using callbacks. Whether it’s simply using callbacks with those standard functions that accept them as … Continue reading
Closure Binding for Unit testing of Private and Protected Methods
Some years ago, I wrote about using closure binding to access protected and private properties when unit testing an object, to verify internal state; and I created the SpyMaster library to simplify that task. One feature that I didn’t include … Continue reading
Closures, Anonymous Classes and an alternative approach to Test Mocking (Part 4)
In a prior article in this series, I described the use of a SpyMaster Class to create proxy spies as anonymous classes, that allow external visibility (and potentially update) of protected and private properties within an object. The same basic principle … Continue reading
Closures, Anonymous Classes and an alternative approach to Test Mocking (Part 3)
I have heard people say that you shouldn’t test abstract classes or traits, only the concrete classes that implement or use them. I don’t follow that approach: unit testing is all about testing in isolation from anything that might affect those … Continue reading
Closures, Anonymous Classes and an alternative approach to Test Mocking (Part 2)
The last time I posted here, I was writing about Anonymous Functions and how they can be bound to any object (or class) to execute as though they are a method within the scope of that class (Closure Binding as … Continue reading
Closure Binding as an alternative to “use” variables
As a general rule when creating a Closure, arguments are passed when the function is called, but “use” variables (I’m sure that they have a formal name, but have no idea what it might be, so I just refer to … Continue reading
Closures, Anonymous Classes and an alternative approach to Test Mocking (Part 1)
Since their first introduction with PHP 5.3, Closures have proven an incredibly useful feature for writing simple callback code, making it cleaner and more intuitive. Anonymous Functions can be used inline for many of the array functions $price = 100.00; … Continue reading
