powermock

问题 I need to write a test that mocks a instance of the java.lang.Class class. Is this possible via PowerMock? I tried to do following: PowerMock.createMock(Class.class); And the result is: java.lang.IllegalAccessError: java.lang.Class at sun.reflect.GeneratedSerializationConstructorAccessor12.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at org.objenesis.instantiator.sun.SunReflectionFactoryInstantiator.newInstance(SunReflectionFactoryInstantiator

问题 I have a class that uses a SecureRandom instance and grabs the next random number. Lets say the example is: public class ExampleClass() { public void method() { Random sr = new SecureRandom(); System.out.printf("%d %n", sr.nextInt(1)); System.out.printf("%d %n", sr.nextInt(1)); } } Test code @RunWith(PowerMockRunner.class) public class ExampleClassTest { ... @Test @PrepareOnlyThisForTest(SecureRandom.class) public void mockedTest() throws Exception { Random spy = PowerMockito.spy(new

问题 I am replacing PowerMock with JMockit in old unit testing case. Below is the PowerMock sample code which mock the File.class constructors with any argument . Can JMockit mock constructors with any argument like it ? The situation is this:myFile is a mock. And I want to simulate returning myFile when calling any constructor in the File class..So What is the code like. // PowerMock whenNew(File.class).withAnyArguments().thenReturn(myfile); // JMockit new Expectations() {{ new File(anyString);

问题 public class A{ private final B b; public void meth() { //Some code Integer a = b.some_method(a,fun(b)); //Some code } private fun(int b) { return b; } } when(b.some_method(anyInt(),anyInt())).thenReturn(100) How to mock the externally dependency when writing unit tests for class A. When i mock dependency in the above way, the value of "a" is not getting assigned to 100 as expected. 回答1: Actually the answer of Jakub is correct. Maybe you need an example to understand how to do it. Check the

问题 I want to unit test this method using mockito/powermock: @Service public class GoogleApiService { private static final Logger logger = LoggerFactory.getLogger(GoogleApiService.class); private static final String LANGUAGE = "es"; private List<AddressType> addressTypes = Arrays.asList( AddressType.LOCALITY, AddressType.ADMINISTRATIVE_AREA_LEVEL_2, AddressType.ADMINISTRATIVE_AREA_LEVEL_1, AddressType.COUNTRY ); @Autowired private GeoApiContext geoApiContext; public String getLocalityFromLatLng

问题 So I have this Mockito unit test: @Test public void createCard() { when(jwtServiceMock.getId(anyString())).thenReturn(validUserToken); when(profileServiceMock.getProfile(validUserToken)).thenReturn(mock(Profile.class)); when(cardServiceMock.countViewableCardsCreatedOrOwnedBy(anyObject())).thenReturn(5L); when(cardServiceMock.countCardsCreatedOrOwned(anyObject())).thenReturn(10L); final Card expectedCard = getCard(); when(cardServiceMock.createCard(anyString(), anyListOf(String.class),
