i am trying to gt a list of method on a particular java class object i have created and trying to unit test it.
It fails saying it cannot find the class with a "java.lang.ClassNotFoundException: class com.jr.freedom.user.User"
here is the testcode:
#Test
public void testRegisterNewUser() throws InvalidDataException {
userService = new UserService();
try {
Class classUser = Class.forName(User.class.toString());
Method m[] =classUser.getDeclaredMethods();
for(int i = 0; i < m.length; i++){
System.out.println(m[i].toString());
}
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
fail(e.getMessage());
}
assertNotNull(createTestUserJson());
}
My project package looks like this:
Inside the project folder:
src
test
the User class is inside src>com>jr?freedom>user (representing com.jr.freedom.user.User)
and the test class is in test>test>com>jr>freedom>user (representing test.com.jr.freedom.user.UserServiceTest)
at first the package name inside /test director was same as the package label in the /src directory for User object but that diddnt work as i thought that the java relfection was trying to retrieve the User object inside the /test folder so i renamed the package so that it is unique and it still did not work. any advice? thanks

The result of User.class.toString() is:
class com.jr.freedom.user.User
See the class before the real classname starts? That makes the string an illegal class name.
You need to use getName().
The toString of the Class class returns: "class com.foo.NameOfClass" So it is trying to load: class com.jr.freedom.user.User (as your error messages states)
But more importantly, you already have the class: User.class, why try to load again? Just take that line out and have:
User.class.getDeclaredMethods...

I'm new in unit-testing and trying to intanciate ApplicationContext in a unit-test as follows:
ApplicationContext context;
#Before
public void init(){
context = new ClassPathXmlApplicationContext("classpath://webapp/WEB-INF/applicationContext-sheduler.xml");
}
But when I try to do so I get the exception:

How to fix that?
The test doesn't contain anything except the Before method and an empty method annotatted with #Test.
In order to use environment variables in log4j.propertiesconfiguration file, you have to pass the argument you need to the JVM when running the test.
YOu can achieve that with a run configutarion:
right-click -> run configurations -> Junit (right click -> new) -> arguments
if you are running the test another way check How to set JVM parameters for Junit Unit Tests?
I have the following method
public class Invoice
{
public String currency="USD";
#NoNull
public BigDecimal getTotal()
{
if ("USD".equals(this.currency))
throw new IllegalArgumentException();
else
return new BigDecimal("1.00");
}
}
The code throws an IllegalArgumentException() when I run it, which is fine. However, when I run a validation test, the checker crashes and throws a ValidationException. I would like to test to continue and report the method that throws exception as failing the validation test. As it stands, any method that throws an exception crashes the validation checker.
The validation checker is
Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<Invoice>> violations = validator.validate(this);
and it throws:

It is possible that the reason why the validation checker crashes is because the exception thrown in your code is never caught. If you surrounded your code with a try/throw/catch block that specifically caught the exception and did something with it then that might fix your problem.
I am new to Mockito, I am using it along with JUnit4 in Eclipse.
I am trying to mock my method as follows:
CartLine line = mock(CartLine.class);
Then I get: FileNotFoundException caused by the call of the supposedly mocked method, as shown in the stacktrace below. How is this the expected behaviour? I am using Mockito precisely to avoid using the whole environment.

(I am not the creator of this code)
it seems to me that you have some kind of static initializer in your CartLine which tried to open file stream.
I will strong suggest you cleanup your code to make it unit-test friendly by removing such kind of static initializer logic. (It is usually more appropriate to make it instance method instead)
Or you may have a dummy `cart.properties1 in your testing resources so that your CartLine can read that.
Or you may consider using PowerMock to see if it help to avoid such problem (I doubt anyway...)
I try to load the following yaml sequence :
- Person(paul):
firstName: Paul
lastName: Lumbergh
children :
- Person(bill)
- Person(jane)
which i tried to load in the following bean :
public class Person {
private long id;
private String firstName;
private String lastName;
private Person father;
private Set<Person> children;
}
I got this error which is due to the fact that snakeYaml load my sequence in a java.util.List instead of java.util.Set.
Is it a way to force snakeYAML to load a sequence in a java.util.Set ?
org.yaml.snakeyaml.error.YAMLException: org.yaml.snakeyaml.error.YAMLException: Cannot set property='children' with value='[Person [firstName=Bill, secondName=Lumbergh], Person [firstName=Jane, secondName=Lumbergh]]' (class java.util.ArrayList) in Person [firstName=Paul, secondName=Lumbergh]

According to the yaml specification the set syntax is the following one :
- Person(paul):
firstName: Paul
lastName: Lumbergh
children : !!set ? Person(bill) ? Person(jane) –
You force SnakeYAML to use List instead of Set. Sets have different representation in YAML: http://yaml.org/type/set.html
You can change the YAML document or instruct SnakeYAML to use sets instead of lists.
You may need to look in tests
I am trying to use Objectify with a set of classes that inherit from an abstract base class:
class Container {
#Id Long id;
#Embedded Set<MyAbstract> children = new HashSet<MyAbstract>();
}
#Entity
abstract class MyAbstract {
#Id Long id;
}
#Subclass class Derived1 extends MyAbstract {}
#Subclass class Derived2 extends MyAbstract {}
Any idea how to code for this situation?

[Edit: This answer is obsolete. Polymorphism works for embedded classes in Objectify v5+]
The polymorphism that Objectify offers (as of 3.0beta2) lets you create polymorphic entities in a manner that is similar (but not identical) to JPA. However, like JPA, this polymorphism does not extend to #Embedded classes.
It is not wholly unreasonable to request this behavior - file a feature request in the issue tracker.
Jeff just added polymorphism in to svn. It is going to be part of the 3.0 release of Ofy.
yours class, dont need a public constructor? Can you check that this is the case?
