Class MockDirectoryWrapper
this is a Directory Wrapper that adds methods intended to be used only by unit tests. It also adds a number of features useful for testing:
- Instances created by LuceneTestCase are tracked to ensure they are closed by the test.
- When a MockDirectoryWrapper is closed, it will throw an exception if it has any open files against it (with a stacktrace indicating where they were opened from).
- When a MockDirectoryWrapper is closed, it runs CheckIndex to test if the index was corrupted.
- MockDirectoryWrapper simulates some "features" of Windows, such as refusing to write/delete to open files.

Properties
| Name | Description |
|---|---|
| AllowRandomFileNotFoundException | If set to true (the default), when we throw random System.IO.IOException on openInput or createOutput, we may sometimes throw FileNotFoundException or NoSuchFileException. |
| AllowReadingFilesStillOpenForWrite | If set to true, you can open an inputstream on a file that is still open for writes. |
| AssertNoDeleteOpenFile | Trip a test assert if there is an attempt to delete an open file. |
| AssertNoUnrefencedFilesOnClose | |
| FailOnCreateOutput | |
| FailOnOpenInput | |
| InputCloneCount | |
| LockFactory | |
| MaxSizeInBytes | |
| MaxUsedSizeInBytes | Returns the peek actual storage used (bytes) in this directory. |
| NoDeleteOpenFile | Emulate windows whereby deleting an open file is not allowed (raiseSystem.IO.IOException). |
| OpenDeletedFiles | |
| PreventDoubleWrite | If set to true, we throw anSystem.IO.IOException if the same file is opened by createOutput, ever. |
| RandomIOExceptionRate | If 0.0, no exceptions will be thrown. Else this should be a double 0.0 - 1.0. We will randomly throw an System.IO.IOException on the first write to an OutputStream based on this probability. |
| RandomIOExceptionRateOnOpen | If 0.0, no exceptions will be thrown during openInput and createOutput. Else this should be a double 0.0 - 1.0 and we will randomly throw an System.IO.IOException in openInput and createOutput with this probability. |
| RecomputedActualSizeInBytes | Like getRecomputedSizeInBytes(), but, uses actual file lengths rather than buffer allocations (which are quantized up to nearest RAMOutputStream.BUFFER_SIZE (now 1024) bytes. |
| RecomputedSizeInBytes | Provided for testing purposes. Use sizeInBytes() instead. |
