|
* Examples: |
|
41
|
|
|
* |
|
42
|
|
|
* TestCommand[SUCCESS][1ms] |
|
43
|

|
44
|
|
|
* TestCommand[TIMEOUT][1ms] |
|
45
|
|
|
* TestCommand[FAILURE][1ms] |
|
46
|
|
|
* |
|
47
|
|
|
* If a command has a multiplier such as <code>x4</code>, |
|
48
|
|
|
* that means this command was executed 4 times with the same events. |
|
49
|
|
|
* The time in milliseconds is the sum of the 4 executions. |
|
50
|
|
|
* |
|
51
|
|
|
* For example, <code>TestCommand[SUCCESS][15ms]x4</code> represents |
|
52
|
|
|
* TestCommand being executed 4 times and the sum of those 4 executions was 15ms. |
|
53
|
|
|
* These 4 each executed the run() method since |
|
54
|
|
|
* |
|
55
|
|
|
* <code>RESPONSE_FROM_CACHE</code> was not present as an event. |
