Java 为什么我在Mockito中得到一个UnifinishedStubException,而存根看起来与文档中的一样?
我有以下使用Mockito框架的测试文件:Java 为什么我在Mockito中得到一个UnifinishedStubException,而存根看起来与文档中的一样?,java,testing,mockito,tdd,stub,Java,Testing,Mockito,Tdd,Stub,我有以下使用Mockito框架的测试文件: @Rule public ExpectedException expectedException = ExpectedException.none(); @Spy private JarExtracter jExt = Mockito.spy(JarExtracter.class); @Test public void inputStreamTest() throws IOException
@Rule
public ExpectedException expectedException = ExpectedException.none();
@Spy
private JarExtracter jExt = Mockito.spy(JarExtracter.class);
@Test
public void inputStreamTest() throws IOException {
String path = "/edk.dll";
// Call the method and do the checks
jExt.extract(path);
// Check for error with a null stream
path = "/../edk.dll";
doThrow(IOException.class).when(jExt).extract(path);
jExt.extract(path);
verifyNoMoreInteractions(jExt);
expectedException.expect(IOException.class);
expectedException.expectMessage("Cannot get");
doThrow()
行返回:
org.mockito.exceptions.misusing.UnfinishedStubbingException:
Unfinished stubbing detected here:
-> at confusionIndicator.tests.JarExtracterTests.inputStreamTest(JarExtracterTests.java:30)
E.g. thenReturn() may be missing.
Examples of correct stubbing:
when(mock.isOk()).thenReturn(true);
when(mock.isOk()).thenThrow(exception);
doThrow(exception).when(mock).someVoidMethod();
Hints:
1. missing thenReturn()
2. you are trying to stub a final method, you naughty developer!
3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed
我尝试了不同的方法来测试这个抛出错误的行为,但我就是无法摆脱这个错误消息,它使我的测试失败。任何帮助都将不胜感激 按照编写的代码,我为
JarExtractor
添加了以下存根,代码运行良好,给出了您期望的IOException:
class JarExtracter {
public void extract(String path) throws IOException{
}
}
将此替换为以下内容,我将得到与您相同的未完成StubbingException:
class JarExtracter {
final public void extract(String path) throws IOException{
}
}
---编辑---如果方法是静态的,同样:
class JarExtracter {
public static void extract(String path) throws IOException{
}
}
正如你在评论中所说,你的方法是静态的,所以你不能用Mockito来模拟它。
这里有一些关于前进方向的好建议,这里也有一些相关的建议。不,它是:
publicstaticvoidextract(stringresourcename)抛出IOException{
Ah,你也不能用Mockito模拟静态方法。我将把它添加到我的答案中。也许我弄错了-你为什么要调用你的“测试中的方法”(`jExt.extract(path);`)在你指定模拟行为之前?!
