Description
Summary of the new feature
When using PSUseCompatible* rules with target profiles for PSv3, PSSA generates a whole bunch of issues for Pester tests that I have inside of my Script/Module projects. My Dev machine, as well as build machines run latest version of PowerShell, and the tests don't get bundled with my script/modules, hence I don't really care whether they'd run on versions other than latest. It would be really great if I could exclude my Test scripts (by path, by name pattern, or by name) just for these rules, and keep the rest of the rules active.
Proposed technical implementation details (optional)
Introduce an additional configuration setting for PSUseCompatible* rules, i.e. IgnoreScriptPath as follows:
@{
Rules = @{
PSUseCompatibleCommands = @{
Enable = $true
TargetProfiles = @(...);
IgnoreScriptPath = @(
'./Tests/', # Ignore any scripts within the Tests sub-folder
'./*.ps1', # Ignore all PowerShell scripts withing the root folder (i.e. build scripts)
'./HelperScripts/SomeHelperScriptForMyBuild.ps1' # Ignore a single helper file
)
};
PSUseCompatibleSyntax = @{
Enable = $true
TargetedVersions = @(...)
IgnoreScriptPath = @(
'./Tests/', # Ignore any scripts within the Tests sub-folder
'./*.ps1', # Ignore all PowerShell scripts withing the root folder (i.e. build scripts)
'./HelperScripts/SomeHelperScriptForMyBuild.ps1' # Ignore a single helper file
)
};
PSUseCompatibleTypes = @{
Enable = $true
TargetProfiles = @(...)
IgnoreScriptPath = @(
'./Tests/', # Ignore any scripts within the Tests sub-folder
'./*.ps1', # Ignore all PowerShell scripts withing the root folder (i.e. build scripts)
'./HelperScripts/SomeHelperScriptForMyBuild.ps1' # Ignore a single helper file
)
};
'PSUseCompatibleCmdlets' = @{
'compatibility' = @(...)
'IgnoreScriptPath' = @(
'./Tests/', # Ignore any scripts within the Tests sub-folder
'./*.ps1', # Ignore all PowerShell scripts withing the root folder (i.e. build scripts)
'./HelperScripts/SomeHelperScriptForMyBuild.ps1' # Ignore a single helper file
)
}
}
}
Alternatively, given that the collection of paths to ignore would most likely be identical for all the PSUseCompatible* rules, it might actually be easier to mention it once in a separate place, i.e.:
@{
Rules = @{
...
}
'PSUseCompatibleRulesIgnoreScriptPath' = @(
'./Tests/', # Ignore any scripts within the Tests sub-folder
'./*.ps1', # Ignore all PowerShell scripts withing the root folder (i.e. build scripts)
'./HelperScripts/SomeHelperScriptForMyBuild.ps1' # Ignore a single helper file
)
}

Research direction
Start by locating the PSUseCompatibleCommands, PSUseCompatibleSyntax, PSUseCompatibleTypes, and PSUseCompatibleCmdlets rule configuration and their existing tests. Compare the two proposed settings, then verify that excluded scripts suppress only these compatibility rules while other rules remain active.
