Tests the parameter sets of the access cmdlets (Add-NTFSAccess, Remove-NTFSAccess, Clear-NTFSAccess,
|
|
Get-NTFSAccess, Get-NTFSOrphanedAccess, Get-NTFSSimpleAccess, Get-NTFSEffectiveAccess) that the judged test matrix
|
|
found untested, with the module built in NTFSSecurity\bin\Release on files in a sandbox folder. Each test closes a
|
|
gap the matrix recorded for the row it names (state, error, pipeline, continuation, or output); it does not repeat
|
|
what Access.Tests.ps1, PathErrors.Tests.ps1, PermissionScopes.Tests.ps1, SecurityDescriptorSets.Tests.ps1, or
|
|
PipelineControl.Tests.ps1 already assert. The -SecurityDescriptor sets of Add-NTFSAccess and Remove-NTFSAccess have
|
|
no per-item error handler (an open item for the maintainer); no test here makes one of those two sets fail.
