Mocking of InitialContext not working in @Tested instantiation #168
Description
I want to test a class that does a new InitialContext().lookup(String) in its constructor:
public class A {
public A() throws NamingException {
new InitialContext().lookup("something");
}
}If A is instantiated via @tested, InitialContext is not properly mocked. A NoInitialContextException is raised on calling lookup()
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

public class ATest {
@Mocked
InitialContext initialContext;
@Tested
A tested;
@Test
public void test() {
}
}Using the MockUp API does not help:
public class AMockUpTest {
@Tested
A tested;
@Before
public void thisDoesNotWork() {
new InitialContextMock();
}
@Test
public void test() {
}
static class InitialContextMock extends MockUp<InitialContext> {
@Mock
public void $init() {
}
@Mock
public Object lookup(final String name) {
return new Object();
}
}
}If class A is instantiated in a @before method, everything seems to be working.
public class A2Test {
@Mocked
InitialContext initialContext;
@Tested
A tested;
@Before
public void thisWorks() throws NamingException {
tested = new A();
}
@Test
public void test() {
}
}public class AMockUp2Test {
@Tested
A tested;
@Before
public void thisWorks() throws NamingException {
new InitialContextMock();
tested = new A();
}
@Test
public void test() {
}
static class InitialContextMock extends MockUp<InitialContext> {
@Mock
public void $init() {
}
@Mock
public Object lookup(final String name) {
return new Object();
}
}
}
