Annotation Type TempDir

@Beta
 @Retention(value=RUNTIME)
 @Target(value=FIELD)
public @interface TempDir

Generate a temp directory for test, and delete it after test.

@TempDir can be used to annotate a member field of type File, Path, or untyped like def/Object in a spec class (untyped field will be injected with Path).

Alternatively, you can use it with any class that has a public constructor with a single File or Path parameter, like FileSystemFixture this way you can use your own utility classes for file manipulation.

If the annotated field is shared, the temp directory will be shared in this spec, otherwise every iteration will have its own temp directory.

Example:

 @TempDir
 File testFile // will inject a File

 @TempDir
 Path testPath // will inject a Path

 @TempDir
 def testPath // will inject a Path

 @TempDir
 FileSystemFixture fsFixture // will inject an instance of FileSystemFixture with the temp path injected via constructor
