如何创建带有子文件夹的JUnit TemporaryFolder

Question

我想创建一个代表这种树的baseFolder的JUnit TemporyFolder:

baseFolder/subFolderA/subSubFolder
          /subFolderB/file1.txt

据我所知，我可以设置一个临时文件夹，然后可以使用"newFolder()"创建位于该文件夹中的伪文件夹。但是我怎么在下面创建图层呢?特别是在测试后清理的方式。

Answer 1

temporaryFolder.newFolder(String... folderNames)以整个层次结构作为参数:

@Rule
public TemporaryFolder temporaryFolder = new TemporaryFolder();
@Test
public void test() throws Exception {
    File child = temporaryFolder.newFolder("grandparent", "parent", "child"); //...
    assertEquals("child", child.getName());
    assertEquals("parent", child.getParentFile().getName());
    assertEquals("grandparent", child.getParentFile().getParentFile().getName());
    System.out.println(child.getAbsolutePath());
}

它通过测试并打印:

/var/folders/.../T/junit8666449860303204067/grandparent/parent/child

Answer 2

TemporaryFolder有一个方法newFolder(String...folderNames)，允许您创建子目录。

tempFolder.newFolder("subFolderA", "subSubFolder")
