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 NewDirectory() are tracked to ensure they are disposed by the test.
When a MockDirectoryWrapper is disposed, 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 disposed, it runs Lucene.Net.Index.CheckIndex to test if the index was corrupted.
MockDirectoryWrapper simulates some "features" of Windows, such as refusing to write/delete to open files.

PreventDoubleWrite

Property Value

Type	Description
System.Boolean

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 a System.IO.Stream based on this probability.

Declaration

public virtual double RandomIOExceptionRate { get; set; }

Property Value

Type	Description
System.Double

| Improve this Doc View Source

RandomIOExceptionRateOnOpen

If 0.0, no exceptions will be thrown during OpenInput(String, IOContext) and CreateOutput(String, IOContext). Else this should be a double 0.0 - 1.0 and we will randomly throw an System.IO.IOException in OpenInput(String, IOContext) and CreateOutput(String, IOContext) with this probability.

public virtual double RandomIOExceptionRateOnOpen { get; set; }

WrapLockFactory

Set to false if you want to return the pure lockfactory and not wrap it with MockLockFactoryWrapper.

Be careful if you turn this off: MockDirectoryWrapper might no longer be able to detect if you forget to close an Lucene.Net.Index.IndexWriter, and spit out horribly scary confusing exceptions instead of simply telling you that.

Declaration

public virtual bool WrapLockFactory { get; set; }

Property Value

Type	Description
System.Boolean
