Pester Assert-MockCalled计算错误

Question

使用Pester和Powershell编写一些测试

代码：

Import-Module Module
Import-Module Pester

InModuleScope Module{

    Describe 'Add-Patchgroup' {

    Context 'Add_server_to_group_fail' {
        Mock Add-ADGroupMember {throw [ADIdentityNotFoundException]} 
        It 'NotCorrectNamingConvention' {
            {Add-Patchgroup -ComputerName "NotExistingServer" | Should -BeLike "WARNING: Could not reach*"}
        }

        It 'CorrectNamingConventionNotExistingServer' {
            {Add-Patchgroup -ComputerName "<nameOfTheServer>" | Should -Throw}
        }

        Assert-MockCalled Add-ADGroupMember -Exactly 1

    }
}
}

并获得以下输出：

 Context Add_server_to_group_fail
      [+] NotCorrectNamingConvention 41ms
      [+] CorrectNamingConventionNotExistingServer 5ms
      [-] Error occurred in Context block 56ms
        Expected Add-ADGroupMember in module PsLeanOps to be called 1 times exactly but was called 0 times
        25:             Assert-MockCalled Add-ADGroupMember -Exactly 1
        at <ScriptBlock>, C:\Users\a.antr01\Desktop\AddPatchGroups.Tests.ps1: line 25
        at DescribeImpl, C:\Users\a.antr01\Documents\WindowsPowerShell\Modules\pester\Functions\Describe.ps1: line 171

为什么没有嘲笑Add-ADGroupMember ？ 要澄清：

Module-模块名称

Add-Patchgroup-PSLeanOps中的功能

Add-ADGroupMember-Add-Patchgroup

中使用的AD cmdlet

编辑

如TheIncorrigible1所说修改了代码。这是最终代码：

Mock Add-ADGroupMember {throw [Microsoft.ActiveDirectory.Management.ADIdentityNotFoundException]::new()} 

            It 'CorrectNamingConventionNotExistingServer' {
                {Add-Patchgroup -ComputerName "<nameOfTheServer>" -ErrorAction Stop} | Should -Throw -ExceptionType "Microsoft.ActiveDirectory.Management.ADIdentityNotFoundException"
            }

            Assert-MockCalled Add-ADGroupMember -Exactly 1

Answer 1

问题在于您的主张。除非您正在使用-Throw，否则它们不应位于脚本块中，但即使如此，也只能使用以下命令：

It 'NotCorrectNamingConvention' {
    Add-Patchgroup -ComputerName "NotExistingServer" | Should -BeLike "WARNING: Could not reach*"
}

It 'CorrectNamingConventionNotExistingServer' {
    { Add-Patchgroup -ComputerName "ATVT1WWFYC050" } | Should -Throw
}

顺便说一句，您是否在代码中包含using namespace语句或添加了类型加速器？ [ADIdentityNotFoundException]应该抛出类型未找到的异常（并且可能被调用两次，因为您两次调用了该函数）。
