TestNG @Test Annotation – using timeOut Attribute

While running test methods there can be cases where certain test methods get struck or may take long time than to complete than expected. In such cases we may need to mark the said test case as fail and then continue with the next test case.

TestNG allows user to configure a time period to wait for a test to completely execute before it can be marked as FAILED.

Here is a quick example

Code

Service Class

package com.skilledmonster.example;
import org.testng.annotations.Test;
/**
* Example to demonstrate use of timeOut attribute of @Test Annotation
*
* @author Jagadeesh Motamarri
* @version 1.0
*/
public class TestNGAnnotationTestMethodTimeOutExample {
@Test(timeOut = 2000)
public void timeOutTestMethodOne() throws InterruptedException {
Thread.sleep(5000);
System.out.println("TimeOut Test Method One!!");
}
@Test(timeOut = 5000)
public void timeOutTestMethodTwo() throws InterruptedException {
Thread.sleep(3000);
System.out.println("TimeOut Test Method Two!!");
}
@Test(timeOut = 2000)
public void timeOutTestMethodRunForEver() {
while (true) {
// Do nothing
}
}
}

In this example there are 3 test methods -

timeOutTestMethodOne() – time out for this method is set to 2 seconds but the current thread that is executing this method goes to sleep for 5 seconds during the executing of the method and eventually the test fails because thread sleep time is more than time out set on the test method.

timeOutTestMethodTwo() – time out for this method is set to 5 seconds but the current thread sleeps only 3 seconds giving a chance for the test method to complete (probably) before the time out.

timeOutTestMethodRunForEver() – this test methods fails after waiting for 2 seconds due to the infinity loop.

Output

 testng_timeout
