Review comment:
       @garydgregory
   In general, unit tests should be white box tests. But I puzzled with this 
PR. Change the position of  the variable currentBufferIndex have no effect on 
the results of public methods, such as write and reset, so I used black box 
tests to illustrate the problem.
   In other words, this PR is not necessary. I will close this issue.
