Question

我想使用JUnit测试用例来测试文件上传组件。我可以使用下面的ode从UI中读取上传的文件来获取UploadedFile.i的模拟实现。

public void XXXX(final FileUploadEvent event) {

        final String uniqueFolderName = this.getUniqueFolderName();

        final org.primefaces.model.UploadedFile uploadedFile = event.getFile();

        final UploadedFileWrapper uploadedFileWrapper = new UploadedFileWrapper(uploadedFile,
                UploadedFile.Status.FILE_SAVED, uniqueFolderName);

        if (!new Boolean(this.multiple)) {
            LOGGER.debug("only single upload is allowed", this.getMultiple());
            this.clearUploadedFiles();
        }

        this.uploadedFiles.add(uploadedFileWrapper);
    }

你能帮我解决一下如何为这个组件创建模拟实现。

Answer 1

这就是Mockito所做的：

    File file = new File("src/test/TestUploadFile.txt");
    InputStream inputStream = new FileInputStream(file);
    FileUploadEvent event = Mockito.mock(FileUploadEvent.class);
    UploadedFile uploadedFile = Mockito.mock(UploadedFile.class);
    Mockito.when(uploadedFile.getFileName()).thenReturn(file.getName());
    Mockito.when(uploadedFile.getContentType()).thenReturn("application/octet-stream");
    Mockito.when(uploadedFile.getInputstream()).thenReturn(inputStream);
    Mockito.when(event.getFile()).thenReturn(uploadedFile);

我拉一个测试文件并创建一个inputStream。然后我模拟FileUploadEvent和UploadedFile并设置我需要的特定属性，您可能需要模拟更多属性。

Did you try..

// Creating a Mock for UploadedFile 
UploadedFile mockFileUploadedFile = EasyMock.createMock(UploadedFile.class);

// Injecting the Mock to FileUploadEvent 
FileUploadEvent fileUploadEvent = new instance...
fileUploadEvent.setFileUploadedFile(mockFileUploadedFile)

如何为Primefaces UploadedFile组件测试JUnit测试用例
