uopz_set_mock

(PECL uopz 5, PECL uopz 6)

uopz_set_mock — Use mock instead of class for new objects

说锟斤拷

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.

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.
