* Test combination for small writes with flush and close operations.

* Test stages:
* 1. Pre-create test file of required size. This is determined by
* startingFileSize parameter. If it is 0, then pre-creation is skipped.
*
* 2. Formulate an append loop or iteration. An iteration, will do N writes
* (determined by numOfClientWrites parameter) with each writing X bytes
* (determined by recurringClientWriteSize parameter).
*
* 3. Determine total number of append iterations needed by a test.
* If intention is to close the outputStream right after append, setting
* directCloseTest parameter will determine 1 append test iteration with an
* ending close.
* Else, it will execute TEST_FLUSH_ITERATION number of test iterations, with
* each doing appends, hflush/hsync and then close.
*
* 4. Execute test iterations with asserts on number of store requests made and
* validating file content.
