我正在尝试编写一个基本的Pester测试,用于检查已解析参数集的“高级”函数:
function Do-Stuff
{
[CmdletBinding(DefaultParameterSetName='Set 1')]
[OutputType([String])]
Param
(
[Parameter(ParameterSetName='Set 1')]
[switch]
$S1,
[Parameter(ParameterSetName='Set 2')]
[switch]
$S2
)
$PSBoundParameters |select -ExpandProperty Keys
}
Describe Do-Stuff {
It 'Returns "S2" when switch "S2" is set' {
$actual = Do-Stuff -S2
$expexted = 'S2'
$actual |Should Be $expexted
}
# How to test the resolved parameter set?
It 'The resolved parameter set is "Set 2" when switch "S2" is set' {
$actual = 'What to do here?' # I'm lost ;(
$expexted = 'Set 2'
$actual |Should Be $expexted
}
}
感谢名单。任何建议都会受到高度赞赏,因为我对Pester完全不熟悉。 ...在豪华和编码方面总体上要好得多:D

您可以使用the Trace-Command
cmdlet。
-Name
参数将设置为ParameterBinderController
。
作为一种入门方式,请尝试这样的事情(在纠缠之外)
Trace-Command -Name ParameterBinderController -Expression { Do-Stuff -S2 } -PSHost
-PSHost
选项将输出发送到主机,以便您可以看到它。
您可能不希望在Pester测试中使用它,并尝试使用其他侦听器选项和捕获输出的方法。

以下内容将测试您是否使用'设置2'对于参数S2:
Describe Do-Stuff {
$Command = Get-Command 'Do-Stuff'
It 'Returns "S2" when switch "S2" is set' {
$actual = Do-Stuff -S2
$expexted = 'S2'
$actual |Should Be $expexted
}
# How to test the resolved parameter set?
It 'The resolved parameter set is "Set 2" when switch "S2" is set' {
$actual = $Command.Parameters["S2"].ParameterSets.Keys
$expexted = 'Set 2'
$actual |Should Be $expexted
# when you use several sets for parameters
$expexted -contains $actual | should Be $true
}
}
跟踪PowerShell是否实际执行'设置2',当你设置它时,不是pester测试的主题...

使用如下:
Function Main{
[CmdletBinding(SupportsShouldProcess=$true,DefaultParameterSetName="ViewOnly")]
Param(
[Parameter(ParameterSetName="ViewOnly")]
[switch]$ViewOnly,
[Parameter(ParameterSetName="NukeAll")]
[switch]$NukeAll
)
Switch ($PSCmdlet.ParameterSetName){
"NukeAll"{
NukeAll
}#end nuke all
"ViewOnly"{
ViewOnly
}#end viewonly
}#end Switch
Function NukeAll {
#Do NukeAll function code here.
}
Function ViewOnly{
#Do ViewOnly function code here.
}
