JMockit : Non-public mock class

Running a simple unit test, with the 'new Object()' syntax.


public void test()
{
Mockit.redefineMethods(emeraldjava.impl.ApplicationCase.class, new Object() {
public void method()
{
System.out.println("JMocked");
}
});
}
ApplicationCaseTest appCase = new ApplicationCaseTest(getName());
assert(appCase.method(),..);
}


I got this error.

Solution

Use an named class


public Test extends TestCase
{

public class AppMock
{
public void method()
{
System.out.println("JMocked");
}
}

public void test()
throws AppException, InformationalException, ClassNotFoundException
{
Mockit.redefineMethods(emeraldjava.impl.ApplicationCase.class, new AppMock());
UICApplicationCaseTest appCase = new UICApplicationCaseTest(getName());
assert(appCase.method(),..);
}
}
