Mini-Filter Testing

NTFSD

Hi,
I need to test a mini-filter and was looking for Test cases. I came across
IFS Tests in DTM. Are these test cases enough to test a mini-filter or we
need to do some additional testing. Can the same tests can be used for
Legacy Driver also.

Thanks
Ash

The IFS tests are a good start but the bottom line is that testing your mini-filter depends a lot on what functionality the filter provides. For some types of filters the IFS tests do not really test the drivers functionality at all. For example, a HSM driver usually operates only on files with it’s reparse point. The IFS tests do not know anything about custom reparse points so nothing it does will create or access files that trigger the HSM code in the driver.

Thanks Rick…That would be helpful…
