Mockery1.0 Mockery Global Configuration

Mockery Global Configuration

To allow for a degree of fine-tuning, Mockery utilises a singleton configuration object to store a small subset of core behaviours. The three currently present include:

• Option to allow/disallow the mocking of methods which do not actually exist
• Option to allow/disallow the existence of expectations which are never fulfilled (i.e. unused)
• Setter/Getter for added a parameter map for internal PHP class methods (Reflection cannot detect these automatically)

By default, the first two behaviours are enabled. Of course, there are situations where this can lead to unintended consequences. The mocking of non-existent methods may allow mocks based on real classes/objects to fall out of sync with the actual implementations, especially when some degree of integration testing (testing of object wiring) is not being performed. Allowing unfulfilled expectations means unnecessary mock expectations go unnoticed, cluttering up test code, and potentially confusing test readers.

You may allow or disallow these behaviours (whether for whole test suites or just select tests) by using one or both of the following two calls:

\Mockery::getConfiguration()->allowMockingNonExistentMethods(bool);
\Mockery::getConfiguration()->allowMockingMethodsUnnecessarily(bool);

Passing a true allows the behaviour, false disallows it. Both take effect immediately until switched back. In both cases, if either behaviour is detected when not allowed, it will result in an Exception being thrown at that point. Note that disallowing these behaviours should be carefully considered since they necessarily remove at least some of Mockery's flexibility.

The other two methods are:

\Mockery::getConfiguration()->setInternalClassMethodParamMap($class, $method, array $paramMap)
\Mockery::getConfiguration()->getInternalClassMethodParamMap($class, $method)

These are used to define parameters (i.e. the signature string of each) for the methods of internal PHP classes (e.g. SPL, or PECL extension classes like ext/mongo's MongoCollection. Reflection cannot analyse the parameters of internal classes. Most of the time, you never need to do this. It's mainly needed where an internal class method uses pass-by-reference for a parameter - you MUST in such cases ensure the parameter signature includes the & symbol correctly as Mockery won't correctly add it automatically for internal classes.
