我正在尝试在 Powershell 中进行简单的并行操作。我正在使用 PoshRSJobs 进行多线程处理,尽管我也尝试过 Invoke-Parallel 处理同样的问题。我需要在作业的脚本主体中调用我自己的几个函数,但这不允许我模拟这些函数以进行单元测试(它们最终成为原始的非模拟函数)。在这一点上,我只是试图断言它们已被正确调用次数。
这是原始类(导入模块的功能无关紧要 - 实际实现当前正在返回测试字符串)......
Import-Module $PSScriptRoot\Convert-DataTable
Import-Module $PSScriptRoot\Get-History
Import-Module $PSScriptRoot\Get-Assets
Import-Module $PSScriptRoot\Write-DataTable
function MyStuff (
param(
[string]$serverInstance = "localhost\SQLEXPRESS",
[string]$database = "PTLPowerShell",
[string]$tableName = "Test"
)
$assets = Get-Assets
$full_dt = New-Object System.Data.DataTable
$assets | Start-RSJob -ModulesToImport $PSScriptRoot\Convert-FLToDataTable, $PSScriptRoot\Get-FLHistory {
$history = Get-History $asset
$history_dt = Convert-DataTable $history
return $history_dt.Rows
} | Wait-RSJob | Receive-RSJob | ForEach {
$full_dt.Rows.Add($_)
}
Write-DataTable $serverInstance $database $tableName $full_dt
}
这是Pester测试...
$here = Split-Path -Parent $MyInvocation.MyCommand.Path
$sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path) -replace '\.Tests\.', '.'
. "$here\$sut"
Describe "MyStuff" {
BeforeEach {
Mock Get-Assets { return "page1", "page2"}
Mock Get-History { return "history" }
Mock Convert-DataTable {
$historyDT = New-Object System.Data.Datatable;
$historyDT.TableName = 'Test'
return ,$historyDT
}
Mock Write-DataTable {}
}
It "should do something" {
{ MyStuff } | Should -Not -Throw;
}
It "should call Get-FLAssetGrid" {
Assert-MockCalled Get-Assets 1
}
It "should call Get-FLHistory" {
Assert-MockCalled Get-History 2
}
It "should call Convert-DataTable" {
Assert-MockCalled Convert-DataTable 2
}
It "should call Write-DataTable" {
Assert-MockCalled Write-DataTable 1
}
}
这是目前 Pester 测试的输出...
Describing MyStuff
[+] should do something 1.71s
[+] should call Get-Assets 211ms
[-] should call Get-History 61ms
Expected Get-History to be called at least 2 times but was called 0 times
23: Assert-MockCalled Get-History 2
at <ScriptBlock>, myFile.Tests.ps1: line 23
[-] should call Convert-DataTable 110ms
Expected Convert-DataTable to be called at least 2 times but was called 0 times
26: Assert-MockCalled Convert-DataTable 2
at <ScriptBlock>, myFile.Tests.ps1: line 26
[+] should call Write-DataTable 91ms
所以最终,我正在寻找一种在 PowerShell 中进行并行操作的方法,并且仍然能够对它们进行模拟和单元测试。
