Do you want some additional validation on the paths, maybe a Test-Path on the NestedModules, RootModule, and RequiredAssemblies.

There are other module properties that specify files, maybe you should be testing those too - TypesToProcess, FormatsToProcess, ScriptsToProcess, maybe FileList and ModuleList?

I wonder if it's a bad idea to specify RequiredAssemblies without a valid assembly - if that's not already causing problems, I can see it causing problems in the future.

The semantics of test-modulemanifest seems to only verify existence of files and not if they are valid. Rather than verify the files exist and being validated, I'm adding a negative test where test-modulemanifest should fail if any paths don't exist

+                CmdletProviderContext cmdContext = new CmdletProviderContext(this);

+
+                foreach (PathInfo pathInfo in pathInfos)


If you resolve to multiple files, shouldn't that be an error instead of just ignoring it?

@lzybkr Since wildcards are explicitly being checked and not allowed in the module manifest, is a Debug.Assert sufficient?

looking at other code in this file, decided to throw

Possible downside here is I'm adding blocks that can't be hit

added negative test cases that do file path checks

SteveL-MSFT

@lzybkr are you ok with the updated changes?

Maybe better use Set-Content ? This is more clearly.

Agree. Fixed.

Why we use -ErrorAction Stop ? It is not a "throw" test. Better -ErrorAction SilentlyContinue.

I used ErrorAction Stop here since Test-ModuleManifest writes to the error stream on manifest errors and I thought this was an easy way to ensure no errors being returned. Otherwise I think I'd have to redirect the error stream and check it and I don't think that's providing additional value. I can add a comment to clarify my intent.

Clear.
Closed.

Typo "parametersAndExecptions" <- "parametersAndErrors"

+            catch {
+                $_.FullQulaifiedErrorId | Should Match "$errorId"
+            }


Why Should BeOfType System.Management.Automation.PSModuleInfo ? If we expect that Test-ModuleManifest raise an exception in the tests the Should BeOfType will be never run.

I suggest using the excellent function ShouldBeErrorId
(I have already prepared new PR #3161 to move existing tests to this pattern)
The new look of this test:

{ Test-ModuleManifest -Path $testModulePath -ErrorAction Stop } | ShouldBeErrorId $errorId

Only insert:

Import-Module $PSScriptRoot\..\..\Common\Test.Helpers.psm1

Cool! will make this change

It looks as unneeded check: Remove-Item implicitly do the check.

… readable fixed typo in test that exposed issue in cmdlet for validating nestedmodules

SteveL-MSFT · 2017-02-22T23:01:39Z

@iSazonov took longer than I expected, after I fixed the typo, I found a issue with the cmdlet

iSazonov · 2017-02-23T16:22:52Z

            "TypesToProcess"="Modules_InvalidManifest";
            "FormatsToProcess"="Modules_InvalidManifest";
-            "RootModule"="Modules_InvalidManifest";
+            #"RootModule"="Modules_InvalidManifest";


Maybe remove it?

Should be uncommented. Looks like the cmdlets doesn't do any validation of RootModule currently, will need to add that code.

iSazonov · 2017-02-23T16:24:32Z

        }
-        foreach ($parameter in $parametersAndExecptions.Keys) {
+        foreach ($parameter in $parametersAndErrors.Keys) {
+            Write-Warning "Testing $parameter"


Not sure what the best practice is here. When doing the test in a loop and something fails, the current error from Pester isn't sufficient to tell you where it failed. @JamesWTruher suggestions?

I suppose we should use TestCases

iSazonov · 2017-02-23T16:28:12Z

+            [string]$errorId = $parametersAndErrors[$parameter] + ",Microsoft.PowerShell.Commands.TestModuleManifestCommand"
+
+            { Test-ModuleManifest -Path $testModulePath -ErrorAction Stop } | ShouldBeErrorId $errorId
            Remove-Item -Recurse -Force $testModulePath


Remove? It seems AfterEach does cleanups.

This is needed as I'm generating a new invalid manifest each iteration of the loop

used TestCases feature of Pester for tests added tests for valid and invalid rootmodules

iSazonov · 2017-02-24T13:50:07Z

+        New-ModuleManifest -Path $testModulePath @args
+        Test-Path $testModulePath | Should Be $true


Below ShouldBeErrorId still catches this error. Maybe remove the line?

Yeah, this isn't needed, originally I thought to check that the manifest was actually created, but it would fail later. Will remove.

It seems it is better to us to split the tests into two and remove the conditions.

Was perhaps over optimizing on code reuse. I'll split it to make it more readable.

I see multiple New-Item but I see no reason optimize them (BeforeAll).

So the tests LGTM.

+                        //RootModule can be null, empty string or point to a valid .psm1, or .dll.  Anything else is invalid.


cdxml and xaml modules are allowed in RootModule just as they are allowed in NestedModules.

Also, when comparing extensions, is ignoring the case correct for non-Windows?

This file contains OrdinalIgnoreCase 4 times. But I see lots of other files to ignore the case when dealing with paths.

Yes, case insensitive comparisons on executable extensions could be a bigger issue than just this file.

I think the extension comparison issue should probably be a separate issue so we can apply same fix everywhere

Created issue #3218

I agree. We don't even have the desired method. Perhaps even better, make a request in .Net.

In testing a fix for cdxml/XAML modules, I see that you get this error message for InvalidModuleManifest which just seems wrong:

PowerShell/src/System.Management.Automation/resources/Modules.resx

Line 157 in 309bf60

<value>The module manifest '{0}' could not be processed because it is not a valid Windows PowerShell restricted language file. Remove the elements that are not permitted by the restricted language:

<value>The module manifest '{0}' could not be processed because it is not a valid Windows PowerShell restricted language file. Remove the elements that are not permitted by the restricted language: {1}</value>

I'd like to change it to something like:

The module manifest '{0}' could not be processed because it is not a valid PowerShell module manifest file. Remove the elements that are not permitted: {1}

Typical use of -TestCases is to introduce a variable - that is probably easier to read.

If there is a good reason to inline the argument - you should prefer parens instead of a backtick.
Extra indentation on the test cases might also make it more readable, so maybe format like:

It "should work" -TestCases ( @{rootModuleValue = "bar.psm1"}, @{rootModuleValue = "bar.dll"} ) { param($rootModuleValue) }

will change
