To answer your question directly, you cannot use Mockito to stub a method called from the constructor. Mockito needs an instance of the class before you can begin mocking, and you haven’t given yourself a way to create an instance for testing. More generally, as mentioned in Effective Java item 17, you should not call … Read more
This is possible using org.mockito.AdditionalMatchers: import static org.mockito.AdditionalMatchers.and; verify(mockClass).doSomething( and(Matchers.startsWith(“prefix”), Matchers.endsWith(“suffix”)); There are also org.mockito.AdditionalMatchers.or and org.mockito.AdditionalMatchers.not.
Was the same problem. Add Mockito 2.22.0 to dependencies. Everything seems to work. compile group: ‘org.mockito’, name: ‘mockito-core’, version: ‘2.22.0’
You are looking for an ArgumentCaptor: Mock mock = Mockito.mock(Mock.class); ArgumentCaptor<String> captor = ArgumentCaptor.forClass(String.class); mock.method(“input”); Mockito.verify(mock).method(captor.capture()); String actualValue = captor.getValue();
It is very likely that the Runnable hasn’t been executed yet by the asyncTaskExecutor when you verify the invocation, resulting in a verification error in your unit test. The best way to fix this is to join on the generated thread and wait for execution before verifying the invocations. If you cannot get the instance … Read more
From Mockito 3.4.0 (2020-07-10), it is possible to mock static methods out of the box even in JUnit 5, without any extension. In the documentation, you can find an example: 48. Mocking static methods (since 3.4.0) Important note: You need to use inline mock maker. So the dependency to use is not the core one: <dependency> … Read more
You need to do this. when(userRepository.save(Mockito.any(User.class))) .thenAnswer(i -> i.getArguments()[0]); And now you can obtain user which you pass as argument.
Powermock 1.6.3 uses javassist 3.15.2-GA which does not support certain types. Using 3.18.2-GA javassist worked for me. You may want to override dependency in your project. <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.18.2-GA</version> </dependency> You may face another problem for which the solution lies here Mockito + PowerMock LinkageError while mocking system class Hope this helps.
I think MockK can help you. It supports mocking extension functions too. You can use it to mock object-wide extensions: data class Obj(val value: Int) class Ext { fun Obj.extensionFunc() = value + 5 } with(mockk<Ext>()) { every { Obj(5).extensionFunc() } returns 11 assertEquals(11, Obj(5).extensionFunc()) verify { Obj(5).extensionFunc() } } If you extension is a … Read more
There are different ways to use Mockito – I’ll go through them one by one. Manually Creating mocks manually with Mockito::mock works regardless of the JUnit version (or test framework for that matter). Annotation Based Using the @Mock-annotation and the corresponding call to MockitoAnnotations::initMocks to create mocks works regardless of the JUnit version (or test … Read more
