Junit Multithreaded Testing

Because a new startup thread is equivalent to executing a method asynchronously, it is difficult to execute in unit tests.

After searching for data, there is a groboutils tool that enables multithreaded testing, http://groboutils.sourceforge.net/

A simple example fragment:

@Test public
    void Grobotest () throws Throwable {
        //Constructs a runner
        testrunnable runner = new Testrunnable () {
 
   @Override public
            void Runtest () throws Throwable {
                //test content
                System.out.println (Thread.CurrentThread (). GetName ());
            }
        ;
        int runnercount = +;
        Rnner array, how many you want to be in concurrency.
        testrunnable[] trs = new Testrunnable[runnercount];
        for (int i = 0; i < Runnercount; i++) {
            trs[i] = runner;
        }
        Runner for executing multithreaded test cases, passing an array of the previously defined single runner into
        multithreadedtestrunner mttr = new Multithreadedtestrunner (TRS);
        Develop concurrent execution of content defined in the array
        mttr.runtestrunnables ();
    }
