Java NullPointerException with Mocked Object

I have a unit test I am writing for a class, and this class uses a ConfigurationManager I wrote to get configuration from a TOML object (and therefore from a TOML file).
The Code
Here is the relevant ConfigurationManager code:
public class ConfigurationManager {
// DEFAULT_LOGGING_LEVEL should represent level to use in production environment.
private final static Level DEFAULT_LOGGING_LEVEL = Level.FINE;
private final static String LOG_LEVEL_ENV_PROPERTY = "LOG_LEVEL";
private final static String TOML_FILE_NAME = "config.toml";
private final static String LOCAL_ENV_PROPERTY = "local";
private final static String ENV_PROPERTY = "MY_ENV";
private static Logger CM_LOGGER;
private Environment environment;
public ConfigurationManager() {
environment = new Environment();
CM_LOGGER = new LoggerUtil(ConfigurationManager.class.getName(), getLoggingLevel()).getLogger();
}
public File getTomlFile() throws URISyntaxException, FileNotFoundException {
URI uri = getConfigURI();
File tomlFile = new File(uri);
if (!tomlFile.exists()) {
String err = TOML_FILE_NAME + " does not exist!";
CM_LOGGER.severe(err);
throw new FileNotFoundException(err);
}
return tomlFile;
}
/**
* #return A URI representing the path to the config
* #throws URISyntaxException if getConfigURI encounters bad URI syntax.
*/
private URI getConfigURI() throws URISyntaxException {
return getClass().getClassLoader().getResource(TOML_FILE_NAME).toURI();
}
/**
* Method for getting the app configuration as a toml object.
*
* #return A toml object built from the config.toml file.
* #throws URISyntaxException if getConfigURI encounters bad URI syntax.
* #throws FileNotFoundException if getTomlFile can't find the config.toml file.
*/
public Toml getConfigToml() throws URISyntaxException, FileNotFoundException {
return new Toml().read(getTomlFile());
}
}
And here is the code that calls this Configuration Manager:
public class Listener {
// Initializations
private static final String CONFIG_LISTENER_THREADS = "listenerThreads";
private static final String DEFAULT_LISTENER_THREADS = "1";
/**
* Constructor for getting app properties and initializing executor service with thread pool based on app prop.
*/
#PostConstruct
void init() throws FileNotFoundException, URISyntaxException {
ConfigurationManager configurationManager = new ConfigurationManager();
int listenerThreads = Integer.parseInt(configurationManager.getConfigToml()
.getString(CONFIG_LISTENER_THREADS, DEFAULT_LISTENER_THREADS));
this.executorService = Executors.newFixedThreadPool(listenerThreads);
LOGGER.config("Listener executorService threads: " + listenerThreads);
}
...
}
And here is the test for that code (See comment to see where NPE is triggered):
public class ListenerTests {
#Mock
ConfigurationManager mockCM;
#InjectMocks
Listener listener = new Listener();
#Before
public void setUp(){
MockitoAnnotations.initMocks(this);
}
#Test
public void testListener_ShouldInit() throws FileNotFoundException, URISyntaxException {
when(mockCM.getConfigToml().getString(any(), any())).thenReturn("5"); // !!!NPE TRIGGERED BY THIS LINE!!!
listener.init();
verify(mockCM, times(1)).getConfigToml().getString(any(), any());
}
}
The Problem
I get a NullPointerException as follows

I have a guess as to the problem here but I'm not sure how to validate my guess. My guess is that I am mocking the ConfigurationManager, but the mock doesn't know that the ConfigurationManager can generate a TOML file which has a getString method, so I end up getting the NPE. This makes me think that I need a mock TOML for my mock ConfigurationManager, but I am neither certain this is the case or that this is the proper solution.
I am new to Mockito and Java in general so any help would be appreciated.

You need to mock every bit of your call, not just the full call. mockCM.getConfigToml() has no mock response, so it returns null, and a toString is invoked on a null object. Your options are to return a non-mocked "Toml" or mock a Toml and then set that up with a when configuration.
Toml tomlMock = Mockito.mock(Toml.class);
when(mockCM.getConfigToml()).thenReturn(tmolMock);
when(tmolMock.getString(any(), any())).thenReturn("5");

You're trying to mock the method of what is returned by calling getConfigToml. That is, you need to mock the object of what should be returned by getConfigToml, and then call getString on that object.

OrientDB 3.0.4 Java OValidationException: The field has been declared as EMBEDDEDLIST but an incompatible type is used

I am using OrientDB version 3.0.4
with Java and orientdb-client.3.0.4 Java driver/library.
I am trying to use EMBEDDEDLIST type as follows:
DB schema:
create class Phone EXTENDS V
create property Phone.number String
create class Profile EXTENDS V
create property Profile.name String
create property Profile.phone embeddedList Phone
Using OrientDB console, following works:
CREATE VERTEX Profile SET name = "User1", phone = [{ "number" : "914" }, { "number" : "212" }]
SELECT * From Profile where name="User1"
+----+------+-------+-----+-------------------------------------+

+----+------+-------+-----+-------------------------------------+
|0 |#198:2|Profile|User1|[Phone{number:914},Phone{number:212}]|
+----+------+-------+-----+-------------------------------------+
Using Java It fails:
While trying to create the Profile Vertex having two Phone(s) objects stored as List (ArrayList), code fails with following exception:

Here are the Java classes:

public Phone(String number) {
this.number = number;
}
public String getNumber() {

public void setNumber(String number) {

}
#Override
public String toString() {

}
}
package com.sample.profile;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collection;
public class Profile {
private String name;
private Collection phone;
public Profile() {
}
public Profile(String name) {
this.name = name;
}
public Profile(String name, Collection phone) {

this.phone = phone;
}
public void addPhone(Phone phoneNumber)
{
if (this.phone == null) {
this.phone = new ArrayList();
}
this.phone.add(phoneNumber);
}
public String getName() {

}
public void setName(String name) {
this.name = name;
}
public Collection getPhone() {
return phone;
}
public void setPhone(Collection phone) {
this.phone = phone;
}
#Override
public String toString() {
return "Profile{" +
"name='" + name + '\'' +
", phone=" + Arrays.toString(phone.toArray()) +
'}';
}
}
Solution:
I resolved the issue as follows:
public void insertProfileTest() throws JsonProcessingException {
LOGGER.info(dbSession.getMetadata().getSchema().getClass(Profile.class).getProperty("name").toString());
LOGGER.info(dbSession.getMetadata().getSchema().getClass(Profile.class).getProperty("phone").toString());
LOGGER.info(dbSession.getMetadata().getSchema().getClass(Phone.class).getProperty("number").toString());
// Init
Profile userProfile = new Profile("Jane Doe");
Phone homePhone = new Phone("212");
Phone cellPhone = new Phone("718");
userProfile.addPhone(homePhone);
userProfile.addPhone(cellPhone);
final String json = MAPPER.writeValueAsString(userProfile);
LOGGER.info("Profile JSON:" + json);
LOGGER.info("Phone Class :" + userProfile.getPhone().getClass().getName());
// DB
List phoneVertexList = new ArrayList();
for (Phone phone: userProfile.getPhone()) {
final OVertex phoneVertex = dbSession.newVertex("Phone");
phoneVertex.setProperty("number", phone.getNumber());
phoneVertexList.add(phoneVertex);
}
final OVertex profileVertex = dbSession.newVertex("Profile");
profileVertex.setProperty("name", userProfile.getName());
profileVertex.setProperty("phone", phoneVertexList, OType.EMBEDDEDLIST);
profileVertex.save();
}
What is not clear to me as per the documentation at
https://orientdb.com/docs/last/general/Types.html for the EMBEDDEDLIST
that it should be of Java type List<Object> but I had to use List<OVertex> .
The documentation states "The Records are contained inside the owner. The contained records have no Record ID's and are reachable only by navigating the owner record" but then in this case Phone vertexes were created as follows:
select * from Profile
+----+-----+-------+--------+-------------------------------------+
|# |#RID |#CLASS |name |phone |
+----+-----+-------+--------+-------------------------------------+
|0 |#41:0|Profile|Jane Doe|[Phone{number:212},Phone{number:718}]|
+----+-----+-------+--------+-------------------------------------+
select * from Phone
+----+-----+------+------+
|# |#RID |#CLASS|number|
+----+-----+------+------+
|0 |#33:0|Phone |212 |
|1 |#34:0|Phone |718 |
+----+-----+------+------+
The documentation at following locations seems very minimal and do not provide example of EMBEDDEDLIST.
https://orientdb.com/docs/last/java/Java-Query-API.html
https://tinkerpop.apache.org/docs/current/reference/#connecting-via-java
I am wondering if anyone can point to better documentation for use of Java API to interact with OrientDB or any GraphDB.

Exception when unmarshalling XML with XStream

I have created some Converter for a javafx.scene.shape.Path which is basically a Bèzier-path. To do that I convert the path elements that are of type MoveTo and CubicCurveTo, for which I have also converters:
public class MoveToConverter implements Converter {
#Override
public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) {
writer.startNode("move-to");
MoveTo start = (MoveTo) source;
writer.addAttribute("startX", String.valueOf(start.getX()));
writer.addAttribute("startY", String.valueOf(start.getY()));
writer.endNode();
}
#Override
public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
reader.moveDown();
MoveTo moveTo = new MoveTo();
moveTo.setX(Double.valueOf(reader.getAttribute("startX")));
moveTo.setY(Double.valueOf(reader.getAttribute("startY")));
reader.moveUp();
return moveTo;
}
#Override
public boolean canConvert(Class type) {
return MoveTo.class.equals(type);
}
}
public class CubicCurveToConverter implements Converter {
#Override
public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) {
CubicCurveTo curveTo = (CubicCurveTo) source;
writer.startNode("cubic-curve-to");
writer.addAttribute("controlX1", String.valueOf(curveTo.getControlX1()));
writer.addAttribute("controlY1", String.valueOf(curveTo.getControlY1()));
writer.addAttribute("controlX2", String.valueOf(curveTo.getControlX2()));
writer.addAttribute("controlY2", String.valueOf(curveTo.getControlY2()));
writer.addAttribute("x", String.valueOf(curveTo.getX()));
writer.addAttribute("y", String.valueOf(curveTo.getY()));
writer.endNode();
}
#Override
public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
reader.moveDown();
CubicCurveTo curveTo = new CubicCurveTo();
curveTo.setX(Double.valueOf(reader.getAttribute("x")));
curveTo.setY(Double.valueOf(reader.getAttribute("y")));
curveTo.setControlX1(Double.valueOf(reader.getAttribute("controlX1")));
curveTo.setControlY1(Double.valueOf(reader.getAttribute("controlY1")));
curveTo.setControlX2(Double.valueOf(reader.getAttribute("controlX2")));
curveTo.setControlY2(Double.valueOf(reader.getAttribute("controlY2")));
reader.moveUp();
return curveTo;
}
#Override
public boolean canConvert(Class type) {
return CubicCurveTo.class.equals(type);
}
}
public class PathConverter implements Converter {
#Override
public void marshal(Object o, HierarchicalStreamWriter writer, MarshallingContext marshallingContext) {
Path path = (Path) o;
List<PathElement> elements = path.getElements();
writer.startNode("bezier-path");
writer.addAttribute("count", String.valueOf(elements.size()));
MoveTo start = (MoveTo) elements.get(0);
marshallingContext.convertAnother(start);
// serialize start
for (int i = 1; i < elements.size(); i++) {
CubicCurveTo curveTo = (CubicCurveTo) elements.get(i);
marshallingContext.convertAnother(curveTo);
}
writer.endNode();
}
#Override
public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
reader.moveDown();
Path path = new Path();
path.setStrokeWidth(2);
path.setStroke(Color.RED);
int nbElements = Integer.parseInt(reader.getAttribute("count"));
MoveTo moveTo = (MoveTo) context.convertAnother(path, MoveTo.class);
path.getElements().add(moveTo);
for (int i = 1; i < nbElements; i++) {
CubicCurveTo curveTo = (CubicCurveTo) context.convertAnother(path, CubicCurveTo.class);
path.getElements().add(curveTo);
System.out.println("Added curve to: "+curveTo);
}
reader.moveUp();
return path;
}
#Override
public boolean canConvert(Class aClass) {
return Path.class.equals(aClass);
}
}
And I have this test code:
Path path = new Path();
path.getElements().add(new MoveTo(2, 1));
path.getElements().add(new CubicCurveTo(1, 2, 3, 4, 5, 6));
path.getElements().add(new CubicCurveTo(11, 12, 13, 14, 15, 16));
path.getElements().add(new CubicCurveTo(21, 22, 23, 24, 25, 26));
path.getElements().add(new CubicCurveTo(31, 32, 33, 34, 35, 36));
path.getElements().add(new CubicCurveTo(41, 42, 43, 44, 45, 46));
XStream xStream = new XStream();
xStream.registerConverter(converter);
xStream.registerConverter(new MoveToConverter());
xStream.registerConverter(new CubicCurveToConverter());
File f = File.createTempFile(getClass().getName(), ".xml");
OutputStream os = new FileOutputStream(f);
xStream.toXML(path, os);
Object result = xStream.fromXML(f);
assertEquals(path.toString(), result.toString());
f.delete();
The file that is created when mashalling the path looks like this, which is what I basically want:
<javafx.scene.shape.Path>
<bezier-path count="6">
<move-to startX="2.0" startY="1.0"/>
<cubic-curve-to controlX1="1.0" controlY1="2.0" controlX2="3.0" controlY2="4.0" x="5.0" y="6.0"/>
<cubic-curve-to controlX1="11.0" controlY1="12.0" controlX2="13.0" controlY2="14.0" x="15.0" y="16.0"/>
<cubic-curve-to controlX1="21.0" controlY1="22.0" controlX2="23.0" controlY2="24.0" x="25.0" y="26.0"/>
<cubic-curve-to controlX1="31.0" controlY1="32.0" controlX2="33.0" controlY2="34.0" x="35.0" y="36.0"/>
<cubic-curve-to controlX1="41.0" controlY1="42.0" controlX2="43.0" controlY2="44.0" x="45.0" y="46.0"/>
</bezier-path>
</javafx.scene.shape.Path>
However when unmarshalling the XML I run into this exception:
com.thoughtworks.xstream.converters.ConversionException: only START_TAG can have attributes END_TAG seen ...<bezier-path count="6">\n <move-to startX="2.0" startY="1.0"/>... #3:41 : only START_TAG can have attributes END_TAG seen ...<bezier-path count="6">\n <move-to startX="2.0" startY="1.0"/>... #3:41

The line 52 in PathConverter points to the this line (first call in the for-loop):
CubicCurveTo curveTo = (CubicCurveTo) context.convertAnother(path, CubicCurveTo.class);
My guess is that the problem has something to do with the moveDown and moveUp method on the unmarshal method, so that the reader is still in the state where it expects the end node of move-to. For the other two converters I also have tests, which run fine, so the problem seems to lie in the combination and the call to context.convertAnother.
I would like to know where my thinking in creating the converter went wrong and how this can be solved.

You're operating on a stream. If the next step does not read the tag's value. May cause an error
try:
reader.moveDown();
Path path = new Path();
path.setStrokeWidth(2);
path.setStroke(Color.RED);
int nbElements = Integer.parseInt(reader.getAttribute("count"));
MoveTo moveTo = (MoveTo) context.convertAnother(path, MoveTo.class);
path.getElements().add(moveTo);
reader.moveUp();
for (int i = 1; i < nbElements; i++) {
reader.moveDown();
CubicCurveTo curveTo = (CubicCurveTo) context.convertAnother(path, CubicCurveTo.class);
path.getElements().add(curveTo);
System.out.println("Added curve to: "+curveTo);
reader.moveUp();
}
return path;

Selenium/JUnit, NullPointerException with a findBy annotation

I create a Java project for training with Selenium and JUnit. A first test connect the user to the website, the second test check an information in the homepage when the user is connected. I don't understand why my second test begin and stop with a NullPointerException...
I use this files :
A main files => for declare a JunitCore and run two class test (via jCore.run(test1.class, test2.class)
main :
public class Main {
public static void main(String[] args){
JUnitCore jCore = new JUnitCore();
//jCore.addListener(new ExecutionListener());
jCore.run(WebsiteLoginTest.class, WebsiteCheckEventTest.class);
}
}
Two tests class files :
test1.java :
public class Test1 {
#Test
public void testlogin(){
WebsiteHomePage homePage = new WebsiteHomePage().open();
homePage.login(...);
}
}
test2.java :
public class WebsiteCheckEventTest {
#Test
public void websiteCheckEvent(){
System.out.println("a");
WebsiteHomePageConnected homePageConnected = new WebsiteHomePageConnected();
System.out.println("b");
homePageConnected.checkEvent();
System.out.println("c");
}
}
And two "page" files : (use page object pattern)
WebsiteHomePage (no logged) :
public class WebsiteHomePage extends WebsitePage<WebsiteHomePage> {
#FindBy(id = "usernameLogin") WebElement usernameInputText;
#FindBy(id = "passwordLogin") WebElement passwordInputText;
#FindBy(id = "loginSubmit") WebElement loginInputSubmit;
#Override
public ExpectedCondition getPageLoadCondition() {
return ExpectedConditions.titleContains("Homepage");
}
#Override
public String getPageUrl() {
return "";
}
public void login(String univers, String login, String password){
usernameInputText.sendKeys(login);
passwordInputText.sendKeys(password);
loginInputSubmit.click();
}
public WebsiteHomePage open() {
return new WebsiteHomePage().openPage(WebsiteHomePage.class);
}
}
WebsiteHomePageConnected (when the user is connected via the first test) :
public class WebsiteHomePageConnected extends WebsitePage<WebsiteHomePageConnected> {
#FindBy(id = "playerName") WebElement playerNameLi;
#FindBy(id = "eventContent") WebElement eventContentDiv;
#FindBy(id = "eventListWrap") WebElement eventListDiv;
#Override
public ExpectedCondition getPageLoadCondition() {
return ExpectedConditions.visibilityOf(playerNameLi);
}
#Override
public String getPageUrl() {
return "";
}
public void checkEvent(String event){
System.out.println("111"); // is displayed in the console
eventContentDiv.click();
System.out.println("222"); // isn't displayed in the console
}
}
When I run the program, the console shows :
a
b
c
111
...but no 222, the program stop in the WebsiteHomePageConnected file in the line with "eventContentDiv.click()" without any error message.
In the main file, if I uncomment //jCore.addListener(new ExecutionListener()) the console show :
a
b
c
111

So, the "eventContentDiv" seems be the problem, but when I check manually the website, after connection, I find the div with the id "eventContent" (via firebug ctrl+f). Manually, More precisely :
I go to the homepage website
I enter log and password, I submit
Im redirected to the homepage connected (the url is a little different)
I open firebug, press ctrl+f, search "eventContent" and I find the element
So...why my program doesn't find this element ?
~UPDATE~
This is the abstract websitePage Class :
public abstract class WebsitePage<T>{
private static final String BASE_URL = "http://www.test.com/";
public T openPage(Class<T> pageObject){
T page = PageFactory.initElements(getDriver(), pageObject);
getDriver().get(BASE_URL + getPageUrl());
ExpectedCondition pageLoadCondition = ((WebsitePage) page).getPageLoadCondition();
WaitForPageToLoad(pageLoadCondition);
return page;
}
private static final int LOAD_TIMEOUT = 30;
private static final int REFRESH_RATE = 2;
private void WaitForPageToLoad(ExpectedCondition pageLoadCondition) {
Wait wait = new FluentWait(getDriver())
.withTimeout(LOAD_TIMEOUT, TimeUnit.SECONDS)
.pollingEvery(REFRESH_RATE, TimeUnit.SECONDS);
}
public abstract ExpectedCondition getPageLoadCondition();
public abstract String getPageUrl();
}
~UPDATE 2~
Ive made a mistake in my com in the public class WebsiteHomePageConnected. Change :
...
System.out.println("222"); // is displayed in the console
...
to
...
System.out.println("222"); // isn't displayed in the console
...

dbunit not able to read data from dataset.xml

I am trying to run a dbunit test case by loading data from an xml file (dataset.xml) and the program fails to find the table. I am new to dbunit and lack of good working examples is preventing me from running a simple program. Can anybody please guide on this?
