Top-level extension methods are not contained within a class. fun IntArray.addTo(dest: IntArray) { for (i in 0 .. size - 1) { dest[i] += this[i] } } Above an extension method is defined for the type IntArray. Note that the object for which the extension method is defined (cal...

The extension method to be called is determined at compile-time based on the reference-type of the variable being accessed. It doesn't matter what the variable's type is at runtime, the same extension method will always be called. open class Super class Sub : Super() fun Super.myExtension()...

A stub is a light weight test double that provides canned responses when methods are called. Where a class under test relies on an interface or base class an alternative 'stub' class can be implemented for testing which conforms to the interface. So, assuming the following interface, public inter...

The terms Mock and Stub can often become confused. Part of the reason for this is that many mocking frameworks also provide support for creating Stubs without the verification step associated with Mocking. Rather than writing a new class to implement a stub as in the "Using a stub to supply c...

Mocks are used when it is necessary to verify the interactions between the system under test and test doubles. Care needs to be taken to avoid creating overly brittle tests, but mocking can be particularly useful when the method to test is simply orchestrating other calls. This test verifies that ...

The json_decode() function takes a JSON-encoded string as its first parameter and parses it into a PHP variable. Normally, json_decode() will return an object of \stdClass if the top level item in the JSON object is a dictionary or an indexed array if the JSON object is an array. It will also retur...

The json_encode function will convert a PHP array (or, since PHP 5.4, an object which implements the JsonSerializable interface) to a JSON-encoded string. It returns a JSON-encoded string on success or FALSE on failure. $array = [ 'name' => 'Jeff', 'age' => 20, 'active' => ...

In this case, building against API 23, so permissions are handled too. You must add in the Manifest the following permission (wherever the API level you're using): <uses-permission android:name="android.permission.CAMERA"/> We're about to create an activity (Camera2Activity.java...
