As long as that's the end of test's life, you're correct. Dealloc of test will automatically happen as a function of your [ test release] statement.

Answer 3

dealloc is automatically called when retainCount is == 0. Each time you call [test release] the retainCount is decreased by one.

In your example everything is fine, since you have alloc test (retain count +1) and then release (retain count 0). Dealloc will be automatically called
