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
Discharging Static #2
In the first article in this series, I wrote about the problems with testing static methods in classes, and showed a few approaches that allow us to write mocks for statics. Testing classes where we have static properties is a … Continue reading
Discharging Static #1
It’s been seven years since Kore Nordmann first published “static considered harmful” on his blog, explaining the problems with using static method calls in classes, and the difficulties that they cause when trying to test that class. Seven years on, … 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
Extending final Classes and Methods by manipulating the AST
We know that we should always write unit tests for our code, and mock dependencies; but that isn’t always easy when we need to mock classes define as final, or that contain final methods. This isn’t normally a problem when … 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
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
