鉴于 Jacoco 在“即时”检测时不能很好地使用 PowerMockito,我一直在尝试配置离线检测,希望这将为使用 PowerMockito 的类提供适当的单元测试覆盖率。
我已将我的 pom 设置如下,但我的测试类的覆盖率仍然为零。非常感谢任何帮助,因为它让我慢慢发疯!

这是我正在测试的类(class):
public class Utils {
private Utils() {
}
public static String say(String s) {
return "hello:"+s;
}
}
这是我的测试:
@RunWith(PowerMockRunner.class)
@PrepareOnlyThisForTest(Utils.class)
@PowerMockIgnore("org.jacoco.agent.rt.*")
public class UtilsTest {
@Test
public void testSay() throws Exception {
PowerMockito.mockStatic(Utils.class);
Mockito.when(Utils.say(Mockito.anyString())).thenReturn("hello:mandy");
assertEquals("hello:mandy", Utils.say("sid"));
}
}
我运行生成 jacoco.exe 的 mvn clean install
覆盖率报告(使用 ant 脚本从 jacoco.exec 生成):-
