/**
|

* Test combination for small writes with flush and close operations.
|
||||
* This test class formulates an append test flow to assert on various scenarios.
|
||||
* 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.
