I have been trying to setup my test framework for Spring data neo4j (version 3.0.1.RELEASE) application. I am using pure java config to setup my test cases.
This is my TestConfig class
#Configuration
#EnableTransactionManagement
#EnableNeo4jRepositories(basePackages = {"com.sitename.data.repository"})
#ComponentScan(basePackages = "com.sitename.data")
public class TestDataConfig extends Neo4jConfiguration {
#Bean(destroyMethod = "shutdown")
public GraphDatabaseService graphDatabaseService() {
return new TestGraphDatabaseFactory().newImpermanentDatabase();
}
#Bean
public Neo4jTemplate neo4jTemplate() {
return new Neo4jTemplate(graphDatabaseService());
}
}
And this is my test class
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(loader = AnnotationConfigContextLoader.class)
public class TestClass {
private UserService userService = UserService.getInstance();
#BeforeClass
public static void setup() {
BaseService.configure(TestDataConfig.class);
}
#Before
public void addData() {
saveOneUser("test#email.com");
}
#Test
public void testMe() {
Assert.assertEquals(0, userService.findAll().size());
}
private User saveOneUser(String email) {
try {
User user = new User();
user.setEmail(email);
user.setFirstName( new Integer(new Random(new Date().getTime()).nextInt(17) + 1).toString() );
return userService.save( user );
} catch(Exception ex) {
System.out.println(ex.getMessage());
}
return null;
}
}
Every time i run the test i am getting the Failed to mark transaction as rollback only error.

Help is appreciated. TIA !
Try and add
#Transactional
on top of your test class to run your tests within a transaction.

This is my test method:
#RunWith(Parameterized.class)
#PrepareForTest(FilenameUtils.class)
public class Test {
//code
private final String datum;
private final String expectedResult;
public Test(String datum, String expectedResult){
this.datum = datum;
this.expectedResult = expectedResult;
}
#Parameters
public static Collection<Object[]> generateData(){
return Arrays.asList(new Object[][] {
{ ".jpg", "productimage..jpg" },
{ "jpg", "jpg.jpeg" },
{ "thequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydog.jpeg", "thequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjump.jpeg" }
});
}
#Before
public void setUp() {
}
#After
public void tearDown() {
}
#Test
public void testSanitizeFilename(){
PowerMock.mockStaticPartial(FilenameUtils.class, "getExtension" , "getBaseName");
expect(FilenameUtils.getExtension(datum)).andReturn("jpeg").anyTimes();
expect(FilenameUtils.getBaseName(datum)).andReturn("productimage").anyTimes();
PowerMock.replay(FilenameUtils.class);
String result = FileUtil.sanitizeFilename(datum, defaultName, contentType);
PowerMock.verify(FilenameUtils.class);
assertEquals(result, expectedResult);
}
}
And this is the method to be tested:
public class FileUtil {
//code
public static String sanitizeFilename(String filename, ............) {
//code here
if (filename.length() > 100) {
FilenameUtils.getExtension(fileName);
FilenameUtils.getBaseName(fileName);
}
return fileName;
}
}
The code works only for the cases that the condition in FileUtil.sanitizeFilename is not true. If it is true (by passing a filename > 100 characters), then the following error occurs:
Unexpected method call FilenameUtils.getExtension("thequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydog.jpeg"):

What is incorrect in my code?
EDIT:
I used Parameterized class in order to avoid the for loop.
I used PowerMock.mockStaticPartial for the static methods getBaseName and getExtension.
How it worked for me
#Test
public void testSanitizeFilename() {
PowerMock.mockStatic(FilenameUtils.class);
EasyMock.expect(FilenameUtils.getExtension(anyString())).andReturn("jpeg").anyTimes();
EasyMock.expect(FilenameUtils.getBaseName(anyString())).andReturn("jpeg").anyTimes();
PowerMock.replayAll();
for (Map.Entry<String, String> entry : fileUrls.entrySet()) {
System.out.println("KEY: " + entry.getKey());
String result = FileUtil.sanitizeFilename(entry.getKey(), entry.getValue());
assertEquals(result, entry.getValue());
PowerMock.verifyAll();
}
}
Note that I modified sanitizeFilename some to get working code for me. And I used
#Rule
public PowerMockRule rule = new PowerMockRule();
instead of RunWith - but as I had all your errors before this might fix your stuff as well.
Seems like mocking inside the loop was no good idea to begin with - once I moved the mocks out of the loop it got me somewhere.
I am using Jetty client API on my application and I want to test my following code using Junit and Mockito:
public void startHttpClient(){
try {
httpClient.start();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
My test case is the following:
#Mock HttpClient httpClient;
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
testBackend= new TestBackend(3,httpClient);
}
#Test
public void teststartHttpClient() throws Exception {
testBackend.startHttpClient();
assertNotNull(httpClient);
verify(httpClient,atLeastOnce()).start();
}
The problem is that the Mock HttpClient inherit the start() method from AbstractLifeCycle, so I got a null pointer exception on the AbstractLifeCycle class:
How can I mock the inherited method start() call fot the class HttpClient?
The Exception got:
java.lang.NullPointerException

I'm having difficulties understanding how to mock/stub an interface with Mockito.
This simple scenario...
public interface Adder
{
int add(int a, int b);
}
public class Calculator
{
Adder _adder;
public Calculator(Adder adder)
{
_adder = adder;
}
public int add(int a, int b)
{
return _adder.add(a, b);
}
}
public class MockitoTester
{
#Test
public void can_mock()
{
Adder adder = mock(Adder.class);
Calculator sut = new Calculator(adder);
assertThat(sut).isNotNull();
}
}
Is giving me this error...

Mockito depends on the artifact net.bytebuddy:byte-buddy. See this POM definition from the Maven repositories. Make sure you get the mockito-all artifact which includes all dependencies in one Jar.
If you are using Maven, then it should automatically resolve the dependency when using mockito-core. You can run mvn dependency:tree on the project to see the hierarchy of your project's dependencies.
I am trying to write a test-case without using a ZUL file for now. I have a very basic function with the following lines.
Class to initialize Listbox:
public class TestComposer {
public void listboxTest(){
ListModelList model = new ListModelList();
Listbox lbOne = new Listbox();
lbOne.setModel(model);
lbOne.setMultiple(true);
System.out.println(lbOne);
System.out.println(model);
}
}
Test-case
public class testSuit {
static ZatsEnvironment env;
#BeforeClass
public static void init() {
System.out.println("Setting server space.");
env = new DefaultZatsEnvironment("/main/webapp/WEB-INF");
env.init("/main/webapp");
}
#AfterClass
public static void end() {
env.destroy();
}
#After
public void after() {
env.cleanup();
}
#Test
public void test() {
TestComposer tc = new TestComposer();
tc.listboxTest();
}
}
This piece of code will produce a null pointer exception. It shows that lbOne is null. Is there a way to use listbox without calling/using a ZUL file?

Line/trace of the NPE error
test.TestComposer.listboxTest(TestComposer.java:12) at test.testSuit.test(testSuit.java:75) at
lbOne.setModel(model);
PS: I am using ZK web framework. I am using a testing tool that can't capture the traces in zats simulated environment. Thus, I want to directly call these methods without depending on ZUL files.
what about using this strategy:
public void listboxTest(){
ListModelList model = new ListModelList();
Listbox lbOne = new Listbox();
lbOne.setModel(model);
lbOne.setMultiple(true);
System.out.println(lbOne);
System.out.println(model);
}
your TestComposer should extend SelectorComposer if you develop in MVC pattern. Please read MVC tutorial
you should test a composer with a zul instead of creating an instance by yourself.
For example, you should apply the composer to a component and run ZATS client to visit the zul. Please read First Mimic Test Case
I am running a simple JUnit test. The test is:
private HangmanModel model;
private WordsToGuess word;
public void setUp()
{
model = new HangmanModel();
word = new WordsToGuess();
}
#Test
public void addWordAndChoose()
{
WordsToGuess testWord = new WordsToGuess("ahoy");
model.addWord(testWord); <---- NullPointerException
String foundWord = model.randomWord();
assertEquals("Not found the word", testWord, foundWord);
}
In WordsToGuess, the constructor is:
public WordsToGuess(String w)
{
word = w;
}
In HangmanModel, the addWord method is:
private ArrayList<WordsToGuess> words;
words = new ArrayList<WordsToGuess>();
public void addWord(WordsToGuess w)
{
words.add(w);
}
This is a REALLY weird NullPointerException since everything should run perfectly fine. It is copied almost word for word from a similar project. Here is the Stack trace:
