Kristian Rosenvold commented on SUREFIRE-793:
---------------------------------------------
Because we only run 1 class at a time with JUnit4, whereas with 4.7+ we send
junit the whole load of classes in one go
> JUnit47 provider reports incorrect time in the XML report
> ---------------------------------------------------------
>
> Key: SUREFIRE-793
> URL: https://jira.codehaus.org/browse/SUREFIRE-793
> Project: Maven Surefire
> Issue Type: Bug
> Components: Junit 4.7+ (parallel) support
> Affects Versions: 2.10, 2.11
> Environment: all
> Reporter: nkeywal
> Assignee: Kristian Rosenvold
> Priority: Minor
> Fix For: 2.11, 2.12
>
> Attachments: surefire_793_trunk.v3.patch
>
>
> With this test:
> {noformat}
> public class Test0 {
> @Test
> public void testT0() throws Exception {
> Thread.sleep(2000);
> }
> }
> {noformat}
> The time presented in the XML report is wrong (close to zero), both for the
> total time and the time spent in the method. It's a side effect of the replay
> mechanism. I can't make it working without hacking the code quite a lot and
> probably breaking the other use cases, so a clean fix would be really
> appreciated. The complete test case would include before & after stuff, like
> this:
> {noformat}
> public class Test0 {
> @Test
> public void testT0() throws Exception {
> Thread.sleep(2000);
> }
> @Test
> public void testT1() throws Exception {
> Thread.sleep(2000);
> }
> @BeforeClass
> public static void setUpBeforeClass() throws Exception {
> Thread.sleep(2000);
> }
> @AfterClass
> public static void tearDownAfterClass() throws Exception {
> Thread.sleep(2000);
> }
> @Before
> public void setUp() throws Exception {
> Thread.sleep(2000);
> }
> @After
> public void tearDown() throws Exception {
> Thread.sleep(2000);
> }
> }
> {noformat}
> The data are correct (at least individual method time) when using JUnit4
> provider.
> It's important, because the XML reports are used by Jenkins, and the test
> time is something we monitor very carefully.
