标记参数Mandatory时，必须为其提供输入值-否则将提示您输入一个值。

从 Get-Help about_Parameters :

 PARAMETER ATTRIBUTE TABLE [...]    Parameter Required?     This setting indicates whether the parameter is mandatory, that     is, whether all commands that use this cmdlet must include this     parameter. When the value is "True" and the parameter is missing     from the command, Windows PowerShell prompts you for a value for     the parameter.

Change your test to:

Describe -Tags "Example" "Palindrome1" {
    It "does something useful" {
        Palindrome1 -param "value goes here" | Should Be $true
    }
}
