Methods

Modifier and Type	Method and Description
void	doStressAllocations(IMemoryManager mm, boolean clear, int tests, int maxString)
protected void	setUp()
protected void	tearDown()
void	test_blockingAllocation() Unit test in which we verify that a thread will block awaiting an allocation until another thread releases an allocation, thereby making enough memory available for the thread to continue.
void	test_largeBlobAllocation() Allocate a blob the size of a single sector.
void	test_read() Unit test for reading a copy of the data from the IMemoryManager.
void	test_stressBlockingAllocation()
void	testAddressMappings() The address mappings are between the integer allocation address and the sector index (16 signed bits) and offset (16 unsigned bits).
void	testAllocationContexts()
void	testAllocationContextsStreams()
void	testNestedAllocationContexts() Rather than creating contexts directly, instead associate with externally created context.
