我有一个静态方法,使用PowerMock进行模拟以抛出异常。(它删除文件。)不幸的是,在我的@After
(每个测试之后)方法中,我需要调用这个没有mock的方法。我该如何取消模拟方法?
我没有找到类似于Mockito.reset()
的方法。[参考:mockito : how to unmock a method?]
例子:
@RunWith(PowerMockRunner.class)
@PrepareForTest(PathUtils.class) // Important: This class has a static method we want to mock.
public class CleaningServiceImplTest2 extends TestBase {
public static final File testDirPath = new File(CleaningServiceImplTest2.class.getSimpleName());
@BeforeClass
public static void beforeAllTests() throws PathException {
recursiveDeleteDirectory(testDirPath);
}
@AfterClass
public static void afterAllTests() throws PathException {
recursiveDeleteDirectory(testDirPath);
}
private File randomParentDirPath;
private CleaningServiceImpl classUnderTest;
@Before
public void beforeEachTest() {
randomParentDirPath = new File(testDirPath, UUID.randomUUID().toString()).getAbsoluteFile();
classUnderTest = new CleaningServiceImpl(randomParentDirPath);
}
@After
public void afterEachTest() throws PathException {
recursiveDeleteDirectory(randomParentDirPath);
}
public static void recursiveDeleteDirectory(File dirPath) throws PathException {
// calls PathUtils.removeFile(...)
}
@Test
public void run_FailWhenCannotRemoveFile() throws IOException {
// We only want to mock one method. Use spy() and not mockStatic().
PowerMockito.spy(PathUtils.class);
// These two statements are tightly bound.
PowerMockito.doThrow(new PathException(PathException.PathExceptionReason.UNKNOWN, randomParentDirPath, null, "message"))
.when(PathUtils.class);
PathUtils.removeFile(Mockito.any(File.class));
classUnderTest.run();
}
}
assertThat(StaticTest.staticMethod()).isNull(); // the undo is going to work in the next test, not here yet.
