Jan*_*ide 5 java mockito powermock
我会假设以下测试应该通过,但是从不抛出异常.有线索吗？
@RunWith(PowerMockRunner.class)
@PrepareForTest(StaticService.class)
public class TestStuff {
@Test(expected = IllegalArgumentException.class)
public void testMockStatic() throws Exception {
mockStatic(StaticService.class);
doThrow(new IllegalArgumentException("Mockerror")).when(StaticService.say("hello"));
verifyStatic();
StaticService.say("hello");
}
}
这是因为你正在使用doThrow ...当静态方法的语法不正确时.有几种不同的方法可以解决这个问题,我已在下面的两个单独的测试方法中概述了这些方法.
@RunWith(PowerMockRunner.class)
@PrepareForTest({StaticService.class})
public class StaticServiceTest {
@Test (expected = IllegalArgumentException.class)
public void testMockStatic1() throws Exception {
String sayString = "hello";
mockStatic(StaticService.class);
doThrow(new IllegalArgumentException("Mockerror")).when(
StaticService.class, "say", Matchers.eq(sayString));
StaticService.say(sayString);
fail("Expected exception not thrown.");
}
@Test (expected = IllegalArgumentException.class)
public void testMockStatic2() throws Exception {
String sayString = "hello";
mockStatic(StaticService.class);
doThrow(new IllegalArgumentException("Mockerror")).when(
StaticService.class);
StaticService.say(Matchers.eq(sayString)); //Using the Matchers.eq() is
//optional in this case.
//Do NOT use verifyStatic() here. The method hasn't actually been
//invoked yet; you've only established the mock behavior. You shouldn't
//need to "verify" in this case anyway.
StaticService.say(sayString);
fail("Expected exception not thrown.");
}
}
作为参考,这是我创建的StaticService实现.我不知道它是否与你的匹配,但我确实验证了测试通过.
public class StaticService {
public static void say(String arg) {
System.out.println("Say: " + arg);
}
}
