uopz_set_mock

(PECL uopz 5, PECL uopz 6)

uopz_set_mockUse mock instead of class for new objects

Description

uopz_set_mock ( string $class , mixed $mock ) : void

If mock is a string containing the name of a class then it will be instantiated instead of class. mock can also be an object.

Note:

Only dynamic access to properties and methods will use the mock object. Static access still uses the original class. See example below.

Parameters

class

The name of the class to be mocked.

mock

The mock to use in the form of a string containing the name of the class to use or an object. If a string is passed, it has to be the fully qualified class name. It is recommended to use the ::class magic constant in this case.

Changelog

Version Description
uopz 6.0.0 Mocking static members is no longer supported by this function. uopz_redefine() and uopz_set_return(), or Componere can be used instead.
