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 withEasyMock
.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 usingwithConstructor(Object...)
. To solve this, you can explicitly define the constructor parameter types to use by callingwithConstructor(Class...)
and thenwithArgs(Object...)
, like this:createMockBuilder(MyMockedClass.class).withConstructor(A.class).withArgs( new A()).createMock();

Method Detail
-
addMockedMethod
IMockBuilder<T> addMockedMethod(java.lang.reflect.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(java.lang.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 otheraddMockedMethod
s in this class if that is the case.- Parameters:
methodName
- name of the method to be mocked- Returns:
- this
-
addMockedMethod
IMockBuilder<T> addMockedMethod(java.lang.String methodName, java.lang.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 mockedparameterTypes
- types of the parameters of the method- Returns:
- this
-
addMockedMethods
IMockBuilder<T> addMockedMethods(java.lang.String... methodNames)
Adds methods to be mocked in the testing class. Same asaddMockedMethod(String)
but to mock many methods at once.- Parameters:
methodNames
- names of the methods to be mocked- Returns:
- this
-
addMockedMethods
IMockBuilder<T> addMockedMethods(java.lang.reflect.Method... methods)
Adds methods to be mocked in the testing class. Same asaddMockedMethod(Method)
but to mock many methods at once.- Parameters:
methods
- methods to be mocked- Returns:
- this
-
withConstructor
IMockBuilder<T> withConstructor(java.lang.reflect.Constructor<?> constructor)
Defines the constructor to use to instantiate the mock. It is expected that you callwithArgs(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(java.lang.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(java.lang.Class<?>... argTypes)

argTypes
- the exact argument types of the constructor- Returns:
- this
-
withArgs
IMockBuilder<T> withArgs(java.lang.Object... initArgs)
Defines the arguments to be passed to the constructor of the class. The types of the arguments must match those previously defined withwithConstructor(Class...)
orwithConstructor(Constructor)
.- Parameters:
initArgs
- the arguments to pass to the constructor- Returns:
- this
-
