This article describes the timeout for testng tests.

The TestNG timeout attribute can be implemented through @test (timeOut = 1000) annotations.

If a test method with @test annotations should be completed in a very short time but executed for a long time, we should study it.

@Test (timeOut = 1000) indicates that this test method should not be completed in 1000 milliseconds (one second). If not done within this time,

This test method also counts as a failure.

Tested class:

Package com.websystique.testng;
 
public class Calculator {public
 
    double add (double A, double b) {return
        a+b;
    }
     
    Public double subtract (double A, double b) throws interruptedexception{
        Thread.Sleep (5000);
        Return A-b
    }
     
}

In the subtract (subtraction) method there is thread.sleep (5000), which lets the thread message 5000 milliseconds.

To write a test class:

Package com.websystique.testng;
Import Org.testng.Assert;
Import Org.testng.annotations.AfterClass;
Import Org.testng.annotations.AfterMethod;
Import Org.testng.annotations.BeforeClass;
Import Org.testng.annotations.BeforeMethod;
 
Import Org.testng.annotations.Test;
 
    public class Testngtimeoutexample {Calculator Calculator;
        @BeforeClass public void Setup () {System.out.println ("setup ()");
    Calculator = new Calculator ();
        @AfterClass public void teardown () {System.out.println ("teardown ()");
    Calculator = null;
    @BeforeMethod public void Beforemethod () {System.out.println ("Beforemethod ()");
    @AfterMethod public void Aftermethod () {System.out.println ("Aftermethod ()");
        @Test public void Testadd () {System.out.println ("Testadd ()");
    Assert.assertequals (Calculator.add (3, 4), 7.0); } @Test (TimeOut = 3000)//timeout in milliseconds publicvoid Testsubtract () throws Interruptedexception {System.out.println ("testsubtract ()");
    Assert.assertequals (Calculator.subtract (5, 2), 3.0); }
 
}

Run test results by testng Eclipse plug-in or MVN clean test

You can see that this test method ran for more than 3 seconds, so the test failed.
