// @file 
// @internalComponent - Internal Symbian test code
// This is a support app used by Apparc\tef\TApparcTestServer (TApparc4Step in particular)
// This application covers the following tests for the static objects
// Test 1 : Existing CCoeStatic derived objects using the 2 parameter
// constructor must be destroyed before the app ui.
// Way to test this,
// Case 1: Get hold of a particular static using CCoeEnv::Static(TUid aUid) 
// in an application's override of CEikAppUi::PrepareToExit() and confirm the 
// returned pointer is not null. 
// Case 2: Then, the same thing is done in the app ui's destructor to check that 
// the pointer is now null.
// Test 2: A static constructed with a negative priority should be accessible from the 
// app ui's destructor, but then destroyed before another static that has a lower priority value.
// Way to test this,
// Case 1: Construct a static (A) using the 3 parameter constructor, specifying a negative priority.
// Then construct another static (B) specifying a priority (A's priority - 1). 
// Check that static A is still non-null when accessed from the app ui's destructor. 
// Case 2: Then check that static A is null when accessed from B's destructor.
// Test 3: Given two statics with different positive priorities,
// the higher priority one should be destroyed first.
// Way to test this,
// Case 1: If (for example) static A has priority EDefaultDestructionPriority,
// and static B has EDefaultDestructionPriority-1, A's destructor should be able to access B,
// Case 2: But B's destructor shouldn't be able to access A.
// Test 4: Statics with priorities immediately either side of the pre/post-destroy app ui should be destroyed before/after the app ui. Should also test that 
// the first negative priority static is destroyed and not "skipped over" when the code calculates
// which static should be destroyed next after the app ui has been destroyed.
// Way to test this,
// Case 1: We could create statics A, B and C with priority zero, -1 and -2 respectively. 
// Then check in the app ui destructor that A is null, and B and C are both non-null.
// Case 2: Then in B's destructor check that C is still non-null.
// Case 3: And in C's destructor check that B is now null.
