Interface IMockBuilder<T>

Type Parameters:
T - type of the object being created
All Known Implementing Classes:
MockBuilder
public interface IMockBuilder<T>
Helps the creation of partial mocks with EasyMock.

Example of usage: 

 public class MyClass {
     public MyClass(A a, B b) {
     }
 }

 public class MyClassTest {
     @Test
     public void testFoo() throws Exception {
         IMocksControl mockControl = createControl();
         A a = mockControl.createMock(A.class);
         B b = mockControl.createMock(B.class);

         MyClass myClass = createMockBuilder(MyClass.class)
                 .withConstructor(a, b).createMock(mockControl);

         // Set the expectations of A and B and test some method in MyClass
     }
 }

This class also has support for partial mocks as shown by the example below: 

 public class MyMockedClass {
     // Empty class is also valid for IMockBuilder.
     public MyMockedClass() {
     }

     public void foo(int a) {
         blah(a);
         bleh();
     }

     public void blah(int a) {
     }

     public void bleh() {
     }
 }

 public class MyMockedClassTest {
     @Test
     public void testFoo() throws Exception {
         MyMockedClass myMockedClass = createMockBuilder(MyMockedClass.class)
                 .withConstructor().addMockedMethod("blah", int.class)
                 .addMockedMethod("bleh").createMock();

         // These are the expectations.
         myMockedClass.blah(1);
         myMockedClass.bleh();
         replay(myMockedClass);

         myMockedClass.foo(1);
         verify(myMockedClass);
     }
 }

Warning: There may be ambiguities when there are two different constructors with compatible types. For instance: 

 public class A {
 }

 public class B extends A {
 }

 public class ClassWithAmbiguity {
     public ClassWithAmbiguity(A a) {
     }

     public ClassWithAmbiguity(B b) {
     }
 }
will cause problems if using withConstructor(Object...). To solve this, you can explicitly define the constructor parameter types to use by calling withConstructor(Class...) and then withArgs(Object...), like this: 
 createMockBuilder(MyMockedClass.class).withConstructor(A.class).withArgs(
         new A()).createMock();

  • Method Details

    • addMockedMethod

      IMockBuilder<T> addMockedMethod(Method method)
      Adds a method to be mocked in the testing class. Each call will add a new method to the result mock. The method is searched for in the class itself as well as superclasses.
      Parameters:
      method - method to be mocked
      Returns:
      this

    • addMockedMethod

      IMockBuilder<T> addMockedMethod(String methodName)
      Adds a method to be mocked in the testing class. Each call will add a new method to the result mock. The method is searched for in the class itself as well as superclasses. There must be no overload of the method. You will have to rely on the other addMockedMethods in this class if that is the case.
      Parameters:
      methodName - name of the method to be mocked
      Returns:
      this

    • addMockedMethod

      IMockBuilder<T> addMockedMethod(String methodName, Class<?>... parameterTypes)
      Adds a method to be mocked in the testing class. Each call will add a new method to the result mock. The method is searched for in the class itself as well as superclasses.
      Parameters:
      methodName - name of the method to be mocked
      parameterTypes - types of the parameters of the method
      Returns:
      this

    • addMockedMethods

      IMockBuilder<T> addMockedMethods(String... methodNames)
      Adds methods to be mocked in the testing class. Same as addMockedMethod(String) but to mock many methods at once.
      Parameters:
      methodNames - names of the methods to be mocked
      Returns:
      this

    • addMockedMethods

      IMockBuilder<T> addMockedMethods(Method... methods)
      Adds methods to be mocked in the testing class. Same as addMockedMethod(Method) but to mock many methods at once.
      Parameters:
      methods - methods to be mocked
      Returns:
      this

    • withConstructor

      IMockBuilder<T> withConstructor(Constructor<?> constructor)
      Defines the constructor to use to instantiate the mock. It is expected that you call withArgs(java.lang.Object...) with the actual constructor argument values after this.
      Parameters:
      constructor - the constructor to be called
      Returns:
      this

    • withConstructor

      IMockBuilder<T> withConstructor()
      Defines the empty constructor should be called.
      Returns:
      this

    • withConstructor

      IMockBuilder<T> withConstructor(Object... initArgs)
      Defines the constructor parameters for the mocked class. The builder will automatically find a constructor with compatible argument types. This throws an exception if there is more than one constructor which would accept the given parameters.
      Parameters:
      initArgs - arguments of the constructor
      Returns:
      this

    • withConstructor

      IMockBuilder<T> withConstructor(Class<?>... argTypes)
      Defines the exact argument types for the constructor to use. It is expected that you call withArgs(java.lang.Object...) with the actual constructor argument values after this.
      Parameters:
      argTypes - the exact argument types of the constructor
      Returns:
      this

    • withArgs

      IMockBuilder<T> withArgs(Object... initArgs)
      Defines the arguments to be passed to the constructor of the class. The types of the arguments must match those previously defined with withConstructor(Class...) or withConstructor(Constructor).
      Parameters:
      initArgs - the arguments to pass to the constructor
      Returns:
      this
