/**
* The ExpectMaxExecutionTime annotation measures the execution time of the test method.
*
*
* Example:
*
* @ExpectMaxExecutionTime(seconds = 2)
* public void executeLongAPIcall() {
* ...
* }
*
*
* QuickPerf will give the following feedback on the console: [QUICK PERF] Execution time of the test method: 5 s 289
* ms (5 289 245 600 ns)
*
*
*
Note:
* Be cautious with time measurement results. It is a rough and first level result. Data has no meaning below the
* ~second/millisecond. JIT warm-up, GC, or safe
* points can impact the measure and its reproducibility. We recommend JMH
* to do more in-depth experiments.
