FileSystemWatcher has no setter in MockFileSystem #1329
Description
In #409 a setter was added to MockFileSystem.FileSystemWatcher. The current version of MockFileSystem does not have a setter for FileSystemWatcher. Is this done intentionally, or is it a regression?
In case the property should not have a setter, how should tests be written for classes that get IFileSystem injected and use it to create a file watcher?

The setter was removed in #782 and it seems on purpose:
So you would have to create a custom
MyMockFileSystemthat inherits fromMockFileSystemand overrides theFileSystemWatcher.Alternatively you could also try to use
Testably.Abstractions, which has a fully working mockedFileSystemWatcher.Dave-Senn commentedon Sep 3, 2025
@vbreuss Thanks for your answer. For me everything is clear and the question/issue can be closed.
