Can't mock "exit"

[jmauerhan]

When I try to mock exit I get an error:

In my test: $this->getFunctionMock('Silva', 'exit');

When I run the test:

1) Test\Unit\ApplicationTest::testRunDefaultsToHelpMenu                                            
ParseError: syntax error, unexpected 'exit' (T_EXIT), expecting identifier (T_STRING) or '('

Other functions can be mocked without this error.

You can't mock exit:

exit is a language construct

PHPMock can only mock functions.

Heh, that makes sense - I was sure I had done it before... hmm... Thanks :)
