java - JUnit 测试文件夹压缩

Question

我已经实现了一种压缩文件的方法。此方法能够压缩子文件夹、覆盖现有的 zip 文件等等。现在我想为此方法创建单元测试。我从包含一些内容的默认 zip 文件开始，这样我就可以测试覆盖等。

我设置源文件的方法:

@Before
public void setUp() throws IOException, URISyntaxException {

    util = new ZipFileUtil();

    parent = folder.newFolder("Parent");
    File subfolder = folder.newFolder("Parent", "Subfolder");
    File sub2 = folder.newFolder("Parent", "Subfolder", "Sub2");

    File f1 = File.createTempFile("file1", ".txt", parent);
    File f2 = File.createTempFile("file2", ".txt", parent);
    File f3 = File.createTempFile("file3", ".txt", parent);

    File f4 = File.createTempFile("file4", ".txt", subfolder);
    File f5 = File.createTempFile("file5", ".txt", subfolder);

    File f6 = File.createTempFile("file6", ".txt", sub2);
    File f7 = File.createTempFile("file7", ".txt", sub2);

    File f8 = File.createTempFile("test", ".txt", sub2);

    File f9 = File.createTempFile("test1", ".txt", parent);

    files[0] = f1;
    files[1] = f2;
    files[2] = f3;
    files[3] = f4;
    files[4] = f5;
    files[5] = f6;
    files[6] = f7;
    files[7] = f8;
    files[8] = f9;

    File file = new File(getClass().getClassLoader().getResource("test.zip").toURI());

    Files.copy(file.toPath(), Paths.get(folder.getRoot().toString(), "test.zip"),
            StandardCopyOption.REPLACE_EXISTING);
}

我的测试:

@Test
public void testOverwriteFilesInExistingZip() throws IOException {
    util.setZipNameGenerator(new ZipNamingStrategy() {

        @Override
        public String getName() {
            // TODO Auto-generated method stub
            return "test";
        }

    });
    util.setOverwriteFilesInExistingZip(true);
    util.setSourceFolder(parent);
    util.setDestinationFolder(folder.getRoot());
    util.generateZip(new FilenameFilter() {

        @Override
        public boolean accept(File dir, String name) {
            return true;

        }
    });
    FileSystem fs = FileSystems.newFileSystem(Paths.get(folder.getRoot().getAbsolutePath(), "test.zip"), null);

    assertEquals("/" + files[0].getName(),
            fs.getPath("/", parent.toPath().relativize(files[0].toPath()).toString()).toString());
    assertEquals("/" + files[1].getName(),
            fs.getPath("/", parent.toPath().relativize(files[1].toPath()).toString()).toString());
    assertEquals("/" + files[2].getName(),
            fs.getPath("/", parent.toPath().relativize(files[2].toPath()).toString()).toString());
    assertEquals(true,
            new File(fs.getPath("/", parent.toPath().relativize(files[8].toPath()).toString()).toString()).exists());

    assertEquals("/file.txt", fs.getPath("/", "file.txt").toString());
    assertEquals("/New Text Document.txt", fs.getPath("/", "New Text Document.txt").toString());
    assertEquals("/test.txt", fs.getPath("/", "test.txt").toString());
    assertEquals("/test1.txt", fs.getPath("/", "test1.txt").toString());

    assertEquals("/Subfolder/file.txt", fs.getPath("/", "test1.txt").toString());
    assertEquals("/Subfolder/desktop.ini", fs.getPath("/", "test1.txt").toString());
    assertEquals("/Subfolder/test.txt", fs.getPath("/", "test1.txt").toString());
    assertEquals("/Subfolder/New Text Document.txt", fs.getPath("/", "test1.txt").toString());

    assertEquals(15, util.getProcessedFiles());

}

我有点不知道如何正确检查 zip 文件是否具有正确的结构(文件必须存在于文件中)。目前我只是检查路径，但这是错误的，我知道。谁能告诉我如何正确测试这种方法？

如果您想检查 zip 文件中是否存在这些文件，可以使用 Files.exist(path) .

如果您想进一步检查实际内容，您可以解压到另一个临时目录，或者要求 Java read directly from the zip file .
