* - retryWhenTransactionTimeout
* The testing of wheel transaction might be fialed randomly by
* timeout. Then, automatically the failed test list will be retested
* automatically only this number of times.
*
* - steps
* This property is array of testing. Each steps must have following
* properties at least.
*
* - func
* This property means function which will be called via
* |setTimeout|. The function cannot have params. If you need
* some additional parameters, you can specify some original
* properties for the test function. If you do so, you should
* document it in the testing function.
* - delay
* This property means delay time until the function to be called.
* I.e., the value used for the second param of |setTimeout|.
*
* And also you need one more property when you call a testing function.
*
* - description
* This property is description of the test. This is used for
* logging.
*
* At testing, you can access to current step via |gCurrentTest|.
