The Performance Testing class enables you to write code to develop good habits of frequent tests and write performance tests.

The Performance Testing class enables you to write code to develop good habits of frequent tests and write performance tests.

Introduction:

It is convenient for the function to be tested to be executed cyclically in the code to automatically calculate the execution time and support multithreading.

 

Usage:

PerformanceTest p = new PerformanceTest (); p. setCount (10); // number of cycles (default: 1) p. setIsMultithread (true); // whether to start the multi-thread test (default: false) p. execute (I => {// code to be tested Response. write (I + "<br>"); System. threading. thread. sleep (1000) ;}, message =>{// output the total running time Response. write (message); // total execution time: 1.02206 seconds });
