JUnit 缺少静态方法调用的行为定义
JUnit missing behavior definition for STATIC method call
这是我的测试方法：
@RunWith(Parameterized.class)
@PrepareForTest(FilenameUtils.class)
public class Test {
//code
private final String datum;
private final String expectedResult;
public Test(String datum, String expectedResult){
this.datum = datum;
this.expectedResult = expectedResult;
}
@Parameters
public static Collection<Object[]> generateData(){
return Arrays.asList(new Object[][] {
{ ".jpg", "productimage..jpg" },
{ "jpg", "jpg.jpeg" },
{ "thequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydog.jpeg", "thequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjump.jpeg" }
});
}
@Before
public void setUp() {
}
@After
public void tearDown() {
}
@Test
public void testSanitizeFilename(){
PowerMock.mockStaticPartial(FilenameUtils.class, "getExtension" , "getBaseName");
expect(FilenameUtils.getExtension(datum)).andReturn("jpeg").anyTimes();
expect(FilenameUtils.getBaseName(datum)).andReturn("productimage").anyTimes();
PowerMock.replay(FilenameUtils.class);
String result = FileUtil.sanitizeFilename(datum, defaultName, contentType);
PowerMock.verify(FilenameUtils.class);
assertEquals(result, expectedResult);
}
}
这是要测试的方法：
public class FileUtil {
//code
public static String sanitizeFilename(String filename, ............) {
//code here
if (filename.length() > 100) {
FilenameUtils.getExtension(fileName);
FilenameUtils.getBaseName(fileName);
}
return fileName;
}
}
该代码仅适用于 FileUtil.sanitizeFilename 中的条件不成立的情况。如果为真（通过传递文件名 > 100 个字符），则会出现以下错误：
Unexpected method call FilenameUtils.getExtension("thequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydogthequickbrownfoxjumpsoverthelazydog.jpeg"):
java.lang.AssertionError

我的代码有什么不正确的地方？
编辑：
我使用参数化 class 以避免 for 循环。
我对静态方法 getBaseName 和 getExtension 使用了 PowerMock.mockStaticPartial。
它对我有用
@Test
public void testSanitizeFilename() {
PowerMock.mockStatic(FilenameUtils.class);
EasyMock.expect(FilenameUtils.getExtension(anyString())).andReturn("jpeg").anyTimes();
EasyMock.expect(FilenameUtils.getBaseName(anyString())).andReturn("jpeg").anyTimes();
PowerMock.replayAll();
for (Map.Entry<String, String> entry : fileUrls.entrySet()) {
System.out.println("KEY: " + entry.getKey());
String result = FileUtil.sanitizeFilename(entry.getKey(), entry.getValue());
assertEquals(result, entry.getValue());
PowerMock.verifyAll();
}
}
请注意，我修改了一些 sanitizeFilename 以获得适合我的工作代码。我用了
@Rule
public PowerMockRule rule = new PowerMockRule();
而不是 RunWith - 但因为我之前遇到过你的所有错误，这也可能会解决你的问题。
似乎在循环内部进行模拟并不是一个好主意 - 一旦我将模拟移出循环，它就让我到了某个地方。
这是我的测试方法：
@RunWith(Parameterized.class)
@PrepareForTest(FilenameUtils.class)
public class Test {
//code
private final String datum;
private final String expectedResult;
public Test(String datum, String expectedResult){
this.datum = datum;
this.expectedResult = expectedResult;
}
@Parameters
public static Collection<Object[]> generateData(){
return Arrays.asList(new Object[][] {

{ "jpg", "jpg.jpeg" },

});
}
@Before

PowerMock.mockStaticPartial(FilenameUtils.class, "getExtension" , "getBaseName");

assertEquals(result, expectedResult);
