Hi experts,
I'm writing a PowerShell function that imports System.Security.SecureString from the pre-exported 'Standard Encrypted String' and 'Encryption Key', and I ran into an issue when I was writing Pester test for it. Here is the simplified example:
function Import-SecureString ($str, $key) {
ConvertTo-SecureString -String $str -Key $key
}
Describe 'Import-SecureString' {
BeforeAll {
$password = '123456'
$encryptionKey = New-Object -TypeName System.Byte[] -ArgumentList 24
$RNGCryptoServiceProvider = New-Object -TypeName System.Security.Cryptography.RNGCryptoServiceProvider
$RNGCryptoServiceProvider.GetBytes($encryptionKey)
$encryptedStandardString = ConvertTo-SecureString -String $password -AsPlainText -Force | ConvertFrom-SecureString -Key $encryptionKey
}
Context 'Unit Test' {
Mock ConvertTo-SecureString
Import-SecureString -str $encryptedStandardString -key $encryptionKey
It 'Should bind VAR $encryptedStandardString to PARAM str' {
$assert = @{
CommandName = 'ConvertTo-SecureString'
Times = 1
Exactly = $true
ParameterFilter = {$String -eq $encryptedStandardString}
}
Assert-MockCalled @assert
}
It 'Should bind VAR $encryptionKey to PARAM key' {
$assert = @{
CommandName = 'ConvertTo-SecureString'
Times = 1
Exactly = $true
ParameterFilter = {$Key -eq $encryptionKey}
}
Assert-MockCalled @assert
}
}
}
In this example, the first 'It' block passed and the second failed, how can I correctly assert the second one?
