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'm starting my first zats-test that follow the example at ZK.
But it returned this error:

It looks like you're missing zats-common from your classpath. You haven't mentioned how you are handling library dependencies nor what version of zats you are using so it's hard to provide more help than that.
Here's my unit test that I expect to pass:
import static org.junit.Assert.assertEquals;
import org.jmock.Expectations;
import org.jmock.Mockery;
import org.junit.Test;
import com.google.common.collect.ImmutableSet;
public class JMockTest {
#Test
public void test() {
Mockery mockery = new Mockery();
final Foo foo = mockery.mock(Foo.class);
mockery.checking(new Expectations() {{
oneOf(foo).bar(); will(returnValue(ImmutableSet.<Long>of()));
}});
ImmutableSet<Long> result = foo.bar();
assertEquals(ImmutableSet.<Long>of(), result);
}
interface Foo {
ImmutableSet<Long> bar();
}
}
However, it throws this error instead:

It seems that JMock is internally attempting to instantiate an ImmutableSet, even though I provided one for it.
See ReturnDefaultValueAction:
private Object collectionOrMapInstanceFor(Class<?> returnType) throws Throwable {
return returnType.isInterface() ? instanceForCollectionType(returnType) : returnType.newInstance();
}
returnType.isInterface() is false b/c it's a ImmutableSet, so JMock calls ImmutableSet.newInstance(), which fails b/c ImmutableSet does not have an accessible constructor.
I assume that people other than me have mocked interfaces that return guava immutable collection objects before, or interfaces that return classes with no visible constructor. How do you deal with this in JMock?
EDIT: This is JMock 2.6.0
EDIT2: This works in JMock 2.8.2!
This seems like a bug with your version of JMock, 2.6.0, as you've described it. Upgrade to the latest, currently 2.8.2. The issue will go away.
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"):
java.lang.AssertionError

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.
Hello im using eclipse with JavaSE-1.6, JUnit 4 and selenium-java 2.43.0.

You need to have an empty constructor:
public Plugin() {
}
Did you define the Person class as abstract?
This is not PostgreSQL or MyBatis issue in my opinion. The VM can't create instance of Person, but constructor args & types is correct.

Try removing the "abstract" and
public Plugin(int id, String name) {
this.id = id;
this.name = name;
}
From the class
