Pester v5 - Failed to run multiple test files

Question

Good morning, I am trying to run several tests in different files test.ps1

The first file always works without problem, but the second one fails. If I add the content of the second file to the first file it works without any problem.

I run the tests with the following configuration (I was using version 4 before and maybe this is where all my confusion comes from)

$pathPs1Tests ="c:/Tests/Sol1/UnitTests/*.tests.ps1"
$pathCodeCoverage = "c:/Tests/Sol1/*.psm1"
$pathOutputCodeCoverage = "c:/Tests/Sol1/Coverage/Coverage-$($sName).xml"
$pathTestXml = "c:/Tests/Sol1/UnitTests/TEST-$($sName).xml"

$container = New-PesterContainer -Path $pathPs1Tests
    $pesterConfig = New-PesterConfiguration
    $pesterConfig.Run.Container = $container
    $pesterConfig.Run.PassThru = $true
    $pesterConfig.CodeCoverage.Enabled = $true
    $pesterConfig.CodeCoverage.Path = $pathCodeCoverage
    $pesterConfig.CodeCoverage.CoveragePercentTarget = 50
    $pesterConfig.CodeCoverage.OutputPath = $pathOutputCodeCoverage
    $pesterConfig.TestResult.OutputFormat = "NUnitXml"
    $pesterConfig.TestResult.OutputPath = $pathTestXml
    $result = Invoke-Pester -Configuration $pesterConfig 

$container contains:

Type Item                                                       Data
---- ----                                                       ----
File C:/Tests/Sol1\UnitTests\AAA.GraphCommon.Component.tests.ps1 {}
File C:/Tests/Sol1\UnitTests\AAA.User.Component.tests.ps1        {}

So I see that pester is loading the two files well with the $pathPs1Tests pattern

Structure for my files:

I think the error is because pester is making the real call, not the "mock call". Output:

if I run the two separate files, both tests work. If I put the content of the second one in the first one also, but if I run it with the code that I have put above it fails because it is not able to fake the call. file 1:

The AAA.MicrosoftGraph.Component.psd1 has:

the test files are both the same: FILE1 (AAA.GraphCommon.Component.tests.ps1

Thanks in advance I'm going crazy:(

Answer 1

Revoke-AAAUserSignInSessions probably use Get-AAAGraphToken to get the authorization-token. I assume Get-AAAGraphToken is defined in the AAA.GraphCommon module.

In File2 you haven't mocked the Invoke-RestMethod that Get-AAAGraphToken calls (it would need -ModuleName AAA.GraphCommon ). Try adding the same mock that worked in File1 into File2:

$parameters = @{
    clientId            = "AAA-000"
    ClientSecret        = "yyyy"
    TenantId            = "testTenant"
    AuthorizationHeader = $true
}
Mock Invoke-RestMethod { return @{ access_token = "xxxxxxxx" } } -ModuleName AAA.GraphCommon
