  • It seems to be a bug in psring boot embedded mongo implementation. Please check the following thread to try different workarounds provided and use the one which works for you. https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo/issues/176 – akshaya pandey Jan 06 '18 at 07:01

Spring by default creates a new Application Context for each test class.

It seems that a new instance of the Embedded Mongo server is also started, but for some reason, the required port is still in use by the instance from a previous test.

As a workaround, I now use the @contextconfiguration annotation to only load Mongo in a single (integration) test class and not in the others.

Use @DirtiesContext to force a reset. For example:

@ContextConfiguration(classes={BlahTestConfig.class})
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
public class SomeTest {

@Autowired XXXX xx;
@Autowired YYYY yy;

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);
    when(YYYY.newYY()).thenReturn(zz);
}

@Test
public void testSomeTest() {
    XX.changeSomething("StringTest");
    XX.doSomething();
    check_for_effects();
}

@Test
public void testSomeOtherTest() {
    XX.changeSomething("SomeotherString");
    XX.doSomething();
    check_for_effects();
}

DirtiesContext Indicates that the underlying Spring ApplicationContext has been dirtied (modified)as follows during the execution of a test and should be closed, regardless of whether the test passed:

  • After the current test class, when declared on a class with class mode set to AFTER_CLASS, which is the default class mode.

  • After each test method in the current test class, when declared on a class with class mode set to AFTER_EACH_TEST_METHOD.

  • After the current test, when declared on a method.

In a JUnit 3.8 environment @DirtiesContext is only supported on methods and thus not at the class level.
