### Question:
AssertionServiceImpl implements AssertionService { @Override public List<AssertionTest> getAssertionTests(final Assertion assertion){ return assertionTestRepo.findAssertionTestsByAssertion(assertion); }  @Override void delete(final Assertion assertion); @Override List<Assertion> findAll(); @Override Assertion find(final Long id); @Override Assertion findAssertionByUUID(final UUID uuid); @Override List<AssertionTest> getAssertionTests(final Assertion assertion); @Override Assertion addTest( Assertion assertion, final Test test); @Override Assertion addTests(final Assertion assertion, final Collection<Test> tests); @Override Assertion deleteTest(final Assertion assertion, final Test test); @Override Assertion deleteTests(final Assertion assertion, Collection<Test> tests); @Override Long count(); @Override AssertionGroup addAssertionToGroup(final Assertion assertion, final AssertionGroup group); @Override AssertionGroup removeAssertionFromGroup(final Assertion assertion, final AssertionGroup group); @Override List<Assertion> getAssertionsByKeyWords(String keyWord, boolean exactMatched); @Override AssertionGroup getAssertionGroupByName(final String groupName); @Override List<AssertionGroup> getAssertionGroupsByNames( final List<String> groupNames); @Override List<AssertionGroup> getAllAssertionGroups(); @Override Assertion create(Assertion assertion); @Override Assertion save(Assertion assertion); @Override List<Test> getTests(Assertion assertion); @Override List<Test> getTestsByAssertionId(Long assertionId); @Override List<AssertionGroup> getGroupsForAssertion(Assertion assertion); @Override List<AssertionGroup> getGroupsForAssertion(Long assertionId); @Override Assertion getAssertionByUuid(UUID uuid); @Override AssertionGroup createAssertionGroup(AssertionGroup group);  }### Answer:
@Test public void testFindAssertionTests() throws Exception { final List<AssertionTest> assertionTests = assertionService.getAssertionTests(assertion); assert assertionTests != null; assert assertionTests.size() > 0; assert assertionTests.contains(assertionTest); }
