powermock

I get an NoClassDefFoundError for org.hamcrest.Matchers, when i run my Test as OSGi PlugIn test, but when i run it as plain JUnit test everthing works as expected. I am using the OSGi version of PowerMock and have all neccessary dependencies in my launch config. What i am doing wrong? It seems like the Testrunner doesnt see the class, for some reason. Edit: I created a reduced sample project and figured out that the Problem only appear when i use @PrepareForTest(XXX.class) in my class declaration. java.lang.NoClassDefFoundError: org/hamcrest/Matchers at eu.gemtec.commons.util.assertion.Assert

Mock private methods 就是mock私有方法啦，学到这不难发现，我们其实大部分都是通过反射去完成单元测试的，但是在实际中，某个类中的私有方法，个人不建议使用反射来测试，因为有时候会覆盖单元测试中的方法，那么下面我们就来举个例子，来使用mock来模拟私有方法的测试。 模拟场景 假设我们按照人名去查找一个学生是否存在 isExist（） ，如果存在就返回true，否则false，同时调用这个类中的私有的查找方法返回学生个数，如果存在返回1，不存在返回0 业务逻辑部分代码比较简单，具体代码如下： package com.rongrong.powermock.mockprivate; /** * @author rongrong * @version 1.0 * @description: * @date 2019/12/5 21:48 */ public class StudentPrivateService { public boolean isExist(String userName) { int count = checkExist(userName); if (count > 0) { return true; } else { throw new NullPointerException(); } } private int checkExist

如何惯用JUnit4来测试某些代码引发异常？ 虽然我当然可以做这样的事情： @Test public void testFooThrowsIndexOutOfBoundsException() { boolean thrown = false; try { foo.doStuff(); } catch (IndexOutOfBoundsException e) { thrown = true; } assertTrue(thrown); } 我记得在这种情况下，有一个批注或一个Assert.xyz或 一些 不那么杂乱无章的 东西 ，更是JUnit的精髓。 #1楼 我在这里尝试了许多方法，但是它们要么很复杂，要么不完全符合我的要求。 实际上，可以很简单地编写一个辅助方法： public class ExceptionAssertions { public static void assertException(BlastContainer blastContainer ) { boolean caughtException = false; try { blastContainer.test(); } catch( Exception e ) { caughtException = true; } if( !caughtException ) { throw new

This question already has answers here : Final method mocking (7 answers) Closed 5 years ago . I need to use a mock who has a final method. So i use powermock but it does not work class B { public final int nb() { return 4; } } @RunWith(PowerMockRunner.class) @PrepareForTest(B.class) public class Exemple extends TestCase { @Test public void test() { B b = PowerMockito.mock(B.class); PowerMockito.when(b.nb()).thenReturn(5); final int actualState = b.nb(); assertEquals(5, actualState); } } if someone has a solution, thank you in advance Your example is fine, should work without any problem.

I have the following code public class A{ public void createFile() { File tempXmlFile = null; String extension = ".xml"; String name = "someName"; try { tempXmlFile = File.createTempFile(name, extension); if (tempXmlFile.exists()) { tempXmlFile.delete(); } } catch (IOException e) { System.out.println(e.getStackTrace()); } } } @RunWith(PowerMockRunner.class) @PrepareForTest(A.class) public class testA extends TestCase{ private A classUnderTest; @Override @Before public void setUp() { classUnderTest = PowerMock.createMock(A.class); //the class is more complex in my case and I have to mock it }

I test custom view class which contain: android ui elements some logic static methods callings dagger2 dependencies So i use next tools for testing Robolectric for UI elements mocking unit tests for logic testing PowerMock for static methods mocking Robolectric + PowerMock integration problem is known and solution is known - https://github.com/robolectric/robolectric/wiki/Using-PowerMock But with this solution dagger2 dependencies fail. Attention to code. My custom view: public class ProgressTextView extends TextView { private String defaultText; private int fileSize; private String
