问题 MyStreamClass mock = mock(MyStreamClass.class); when(mock.streamMethod()).thenReturn(Stream.of("A", "B")); System.out.println(""+mock.streamMethod().findFirst()); System.out.println(""+mock.streamMethod().findFirst()); the second call of findFirst will throw java.lang.IllegalStateException: stream has already been operated upon or closed 回答1: Try the thenAnswer instead of thenReturn : Answer<Stream> answer = new Answer<Stream>() { public Stream answer(InvocationOnMock invocation) throws

Mockito's Answer in ScalaTest

由 本小妞迷上赌 提交于 2020-08-24 06:44:09
问题 Is there some alternative to Mockito's Answer in ScalaTest? I was going through its documentation, but didn't find anything. I would like to, for example, execute some logic on arguments of a stubbed method. In Mockito, I would do something like this: when(mock.create(any(A.class))).thenAnswer(new Answer() { Object answer(InvocationOnMock invocation) { A firstArg = (A) invocation.getArguments()[0]; firstArg.callMethod(); return null; } }); In ScalaTest, I'm fine with using Mockito, as well.

Instantiating a Class with private constructor using Java/Mockito/PowerMockito

由 大城市里の小女人 提交于 2020-08-07 05:47:38
问题 I am writing a test case using JUnit and the method under test takes a final class with a private constructor as a parameter. Since I cannot instantiate it with the new keyword I tried using Mockito but found out that Mockito doesn't like final class . I went to use PowerMockito which seemed reasonable to me but PowerMockito.mockStatic(Field.class); is a void method and I need a reference of Field so that I can pass it as an argument while invoking the method. I want to catch

Mockito 是很常用的测试工具，使用过程中可能会遇到下面的问题： Mockito cannot mock/spy because : - final class 问题重现： 引入该依赖到项目的maven配置如下： <dependency> <groupId>org.mockito</groupId> <artifactId>mockito-core</artifactId> <version>3.3.3</version> </dependency> 测试代码如下： package com.pkslow.basic; import org.junit.Assert; import org.junit.Test; import static org.mockito.Mockito.mock; import static org.mockito.Mockito.when; public class MockitoTest { public static final class FinalPumpkin { public String getName() { return "pkslow.com"; } } @Test public void test() { FinalPumpkin pumpkin = mock(FinalPumpkin.class); when(pumpkin
