Record time it takes JUnit tests to run

Question

I would like to record how long it takes my JUnit test to run programmatically. I have a large number of tests in various test classes, and I would like to find out how long ea

Answer 1

If you use @Before and @After annotations and note the junit testcase start and endtime. Then finding the difference of two timestamps should give you the testcase execution time. Something like this:

 public class Example {

    long startTime;
    long endTime;

    @Before public void recordStartTime() {
        startTime = System.currentTimeMillis();
    }
    @Test public void testSomething() {
          //test method
    }
    @After public void recordEndAndExecutionTime() {
        endTime = System.currentTimeMillis();
        System.out.println("Last testcase exection time in millisecond : " + (endTime - startTime));
    }
 }
